Sammendrag:

Hydrologien i de sentrale deler av Bohol-provinsen på Filippinene er vurdert på grunnlag av feltbefaring og analyse av allerede publiserte nedbør- og avløpsdata.

Datagrunnlaget for estimering av hydrologiske parametre til bruk ved forprosjektstudie av vannkraftverk i provinsen er relativt spinkelt. Middelavløp, flomstørrelser og lavvannsverdier er overført til prosjektområdene ved hjelp aven antatt sammenheng med nedbørfeltenes størrelse og beliggenhet. Varighetskurven fra den antatt beste måle• stasjonen er foreløpig valgt som representativ for de sentrale deler av Bohol.

En vesentlig kompliserende faktor er de karst-hydrologiske problemene i området. Eksistensen av drenering i undergrunnen er åpenbar enkelte steder. Det topografiske og hydrologiske vannskillet stemmer ikke overens for nedslagsfeltet til Bilar River. En reduksjon til effektivt drenering sa real er antydet.

En forsvarlig analyse av hydrologien i området krever at supplerende målestasjoner opprettes så snart som mulig. Enkelte eksisterende måle• stasjoner kan dessuten forbedres. Flere alternativer for plassering av nye målestasjoner er foreslått. MAP OF THE PHILIPPINES

I forbindelse med en forprosjektstudie av muligheten for småkraftverk på Filippinene, "Rural Hydropower Development for Bohol, Antique (Panay) and Mindoro", ble Hydrologisk Avdeling anmodet av NORCONSULT A.S. om å vurdere datagrunnlaget samt å estimere de nødvendige hydrologiske parametre for provinsen Bohol.

En feltbefaring ble foretatt i februar 1980. Beregningsarbeidet bygger for en stor del på avløpsdata pUblisert i Filippinske årbøker. Dessuten er det innhentet supplerende opplysninger ved direkte kontakt med de lokale hydrometeorologiske myndigheter.

Rapporten inneholder en kort geografisk beskrivelse av området og oversikt over det eksisterende stasjonsnett for måling av nedbør og avløp. Analysen er i alt vesentlig foretatt ved hjelp av Hydrologisk Avdelings standard EDB-program og kjørt på NVE's CYBER 171. Data­ grunnlaget er gjengitt i Appendix.

DESCRIPTION OF CATCHMENTS

The geography of Bohol is dominated by three major river systems, the Loboc River, the Abatan-Sinigan River and the Wahig River (see Drawing 101).

Central Bohol is heavily cultivated, and is the major producer of crops in the province, as rainfall occurs throughout the year. Though extensive rainfall occurs mostly during April to October caused by the SW monsoen, most rivers are perennial. The farmers are able to harvest rice three times a year.

The Loboc River system rises in the range of mountains along the eastern and southern outskirts of the Central Bohol plateau. The Cantimok River runs northwest and Bilar River runs first southwest then northwest before they join to form the Loboc River. The Lobayog River and the Sampelangon River drain the northern parts of the catchment. By the time Loboc River enters the sea it drains 650 km 2 • The topographical boundaries were drawn on a 1:50,000 scale map (see Drawing 121). The catchment consists mainly of karst limestone and sandstones (5). Evidence of natural springs appearing in the hillsides along the southern coast indicates a disagreement between the hydro1ogical and topographical catchment boundaries in the mountain range. Numerous sinkholes in the areas north of Bilar probably 1ead to resurgence further downstream, as observed in the Loboc River near Janopol.

The major part of the catchment is dominated by a p1ateau with scattered hills in between flat or gently sloping cultivated areas where the river gradient is low. Thereafter a canyon is formed where the river gradually loses altitude until sea level is reached some 5-6 km from the southern coast.

Agricultural activities including gravity irrigation are common all over BOhol, especially within the Carmen, Dagohoy and Pilar munici­ palities where pumped irrigation is utilized as well (7). Still the actual irrigated area is mostly less than 10% of total cultivated area within a municipality, mainly due to the persistence of rain­ fall throughout the year.

The Wahig River emerges from the highest, eastern parts of the Sagungan Mountains and runs mainly northwest. When the river reaches the coast it drains about 600 km 2, mainly areas northeast of the Loboc River catchment. The boundaries were drawn on a 1:50,000 scale map (see Drawing 122). After having passed through heavily cultivated areas, the river cuts through the hills downstream of Tipolo. In this canyon-like valley are the main falls and rapids and a 30 meter loss of altitude along 5 km occurs. The 10 meter contour is reached already some 20-25 km from the coast. Though limestone appears along the southern boundaries, underground drainage is not considered to be a problem within the Wahig catchment.

The Abatan-Sinigan River system drains 365 km 2 to the west of the Loboc River system, emerging from the western outskirts of the Central Bohol plateau. Three main tributaries combine to form Sinigan River near Baunos, two of them with a relatively steep 6

gradient entering from the north while the Sinigayanan River drains the gently sloping cultivated areas in the north-eastern part of the catehment. A 50 m drop through the canyon over the next 5-6 km leads down to the 10 m contour where the steep Camugan River runs in from the east some 15-20 km from the coast. Apart from the limited sand­ stone formations to the west of , the Abatan-Sinigan catch­ ment is dominated by the limestone. The catchment has no significant differences in altitude between adjacent catchments, such as occur in the Bilar/Loboc configuration. Therefore major loss of water by underground drainage is not considered a major problem, though minor local seepage from one subcatchment to another may occur. The catchment boundaries were drawn on a 1:50,000 scale map (see Drawing 123).

RAINFALL

The number of long term rainfall stations in Bohol with relatively unbroken records is very limited. Table l shows available stations. Records of monthly and annual summaries are listed in Appendix A as copied from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) (2).

The first station in the province was started at in 1902 as a synoptic station. Unfortunately, a gap of 20 years from 1940 to 1960 disturbs a valuable long term record. Otherwise records date back only to the 1960s or later.

Standard 125 mm diameter rain gauges are used, set about 1/2 m above ground level. Gauges are usually kept in enc10sures. Except for the Pamacsalan station which has a somewhat bad exposure to northerly winds, all stations are satisfactorily located. The reliability of the records is considered adequate. Monthly and annual summaries are displayed on Drawing 101.

Average annual rainfall over the plateau is 2000-2100 mm. The western and southern areas, from Loboc towards the Abatan-Sinigan River, probably receive less rain, being at lower elevation, but there are no rainfall records to support this assumption and there is no way to allow for differences in exposure to the southwest winds.

RUNOFF

Streamflow data have traditionally been collected by the Bureau of Public Works, Water Resources Survey Division (BPW-WRSD). In recent years there has been a decline of financial support for the operation and maintenance of streamflow gauging stations by the BPW (3), thus the quality of data has deteriorated. No calibration of rating curves has been carried out since 1972.

National Power Corporation (NPC) and National Irrigation Administration (NIA) and some regional development agencies have been erecting stations in cooperation with BPW during the last few years. Nevertheless the length of these records is inadequate for this study.

Longterm records have been published by BPW in Water Supply Bulletins (WSB) (l). Relevant stations are listed in Table 2. Locations are indicated on Drawing 101.

The stations were commenced by reading a staff gauge two or three times a day. Later, water stage recorders were installed at all but the Pamacsalan station. Equipment and procedures have usually been according to u.s. Geological Survey standards.

Data processing and publication was initiated in 1952-53 by a U.S.G.S. mission. Published data are copied in Appendix B, containing daily ave rage flow as well as monthly and annual summaries. Background material for the calculation of published run­ off records is difficult to recover as most of it has been lost or damaged due to various reorganisations and change of office 10cations of the BPW-WRSD. The possibilities of performing a thorough check on previous processing are very limited indeed. One has to accept the calculated runoff together with the indication of quality as given in the comments to each station. A limited number of discharge measure­ ments show shifting controls at most stations.

Recent field trips indicate that stations have not been maintained properly or have been neglected completely due to the financial constraints. This applies to the period 1972 and onwards. There­ fore, by utilizing records up to 1971 only, the pub1ished data and comments are considered adequate. Inspections in the field did revea1 possible sources of error due to diversions of water for irrigation upstream of gauging stations (4). 8

RIVER GAUGING STATIONS

Loboc River at Tigbao, 618 km 2

The station, which gauges 95% of the total Loboc catchment, was erected as early as 1922. During the second world war the bulk of the early records were destroyed. Available records date from the period 1955-1971, with a short break during November and December 1968. A water stage recorder operated from May 30, 1962, to December 2, 1964. Readings have been made twice a day.

The site is located about 2 km upstream of the Lotonan falls, where the present NPC Hydro Power Station has been operating since 1957. Prior to 1968 flood levels at Tigbao were controlled by the rock bar at the tap of the falls. The existence of a 10w/medium flow control further upstream is somewhat difficult to judge. Since 1968 a spill­ way constructed on the rock bar raising its level by 1.70 m has given variable backwater at all levels depending on the spillway operation and the rate of water intake for power production. The records after 1968 may not be as reliable as those before 1968 therefore. A Bailey bridge near the site should give reasonable conditions for taking discharge measurements at medium and 10w flows. Floods will cause turbulence around the brigde footing situated in the middle of the river. A staff gauge is attached to the bridge pier and includes a crest level recorder.

Discharge measurements and the corresponding water levels at Tigbao are listed in Table 3 and plottet on Figure 3. The highest flow recorded is 52 m3/sec. Records are judged to be good up to 60 m3/sec representing 95% of the total volume of water. By estimating average monthly flow for November and December 1968, the average discharge at Tigbao amounts to 19 m3/sec or 30.7 l/sec/km2 based on the topographical catchment area. A correction has to be made, for the probable loss of water due to the karst conditions in the Bilar subcatchment.

Monthly runoff statistics for Loboc River are shown on Figure l. 9

Bilar River at Owac, 67 km 2

The Bi1ar River drains topographically 226 km 2, equivalent to about 50% of the total catchment at the point of confluence with the Loboc River near Janopol. A re-examination of the topographic boundaries on the 1:50,000 scale map, demonstrated the WRB published catchment area at the gauging station to be wrong, and the figure had to be reduced from 92 km 2 to 67 km 2

The Owac station represents 30% of the total Bilar catchment. The gauge has been read twice a day since July 1959. A stage recorder was installed in July 1961. Records from a previous gauge 200 m further downstream cannot be traced.

The control consists partly of loose medium-sized stones. High flow is affected by backwater from a diversion dam 400 m downstream. The existence of karst features at the gauge site is evident.

17 discharge measurements taken between 1965 and 1970 (Table 4) demonstrate continual shifting of datum. Great reliance cannot be placed on these records therefore.

The very low recorded yield 7 1/sec/km2 is most probably far from representative for the size and exposure of the catchment only. It is assumed that the area is heavily affected by the karst limestone causing a major loss of water through underground drainage, especial1y towards the southwest. The steep descent of the duration curve below medium flow probably reflects the same effect (Figure 5). Numerous natural springs can be observed in the hill­ sides along the southern coast, indicating great disagreement between the hydrological and topographical catchment boundaries in 10

the mountain range. On the other hand any leakage through limestone formations downstream to the north of the Owac station will probably lead to resurgence before reaching Tigbao gauging station.

Monthly runoff statisties are shown on Figure l.

Wahig River at Bugsoc, 38 km 2

In the catchment area several hills reach to more than 800 m altitude. The gauging station is located near Bugsoc . The description given in Water Resources Bulletin is partlya confusion with the Pamacsalan station. The river changed its course during a flood in 1956 to join a tributary upstream of Bugsoc. Thereafter the station was relocated 1.5 km further downstream to its present site, increasing the catchment from 25 km 2 to 38 km 2. The location of the new station and the size of the new catchment area has not been corrected accordingly in the Bulletins.

The gauge was originally read 3 times a day. A stage recorder has been operating since February 1957. At the time of relocation the new station was equipped with a cableway.

The present control is not well defined. The gauge is situated in the middle of a gradually falling river bed covered with loose stones and gravel liable to changes during floods.

The 22 discharge measurements taken, (Table 5) during the 1963-70 period indicate substantial changes of the control, especially concerning low levels during 1968-69. 11

Records are available from 1955 to 1971. A few days missing during 1960-63 affect slightly the overall picture. Flow below 75 l/sec during Jan 1957 to Dec 1959 published in Vo1ume l of the Bulletin was revised in later volumes. From 1969 the published data are classified as "poor".

There are several diversion dams upstream, periodically diverting at least 80% of the f10w for rice irrigation purposes. These con­ structions are re-erected by the local inhabitants when destroyed by floods. In periods of no irrigation the dams are still active, but the diverted water bypasses the ricefields, as well as the gauging station.

These records are not very reliable therefore, due to poor rating as well as the diversion of water outside flooding seasons. The average measured flow of 31 1/sec/km2 is probably too low.

Monthly flow statistics are shown on Figure 2.

Wahig River at Pamacsalan, 28 km 2

Pamacsalan River is a tributary joining the Wahig River 4 km down­ stream of . The catchment comprises one southern and one eastern branch. The southern one is gauged near Pamacsalan barangay. 12

The catchment size given in WSB was found to be wrong. Re-exami­ nation of the topographic boundaries on the 1:50,000 scale map reduced the area from 71 km 2 to 28 km 2. The highest mountain reaches 780 m above sea level.

The records date back to August 1956, mostly based on readings taken twice a day. Low flow control is fairly stable. The 16 discharge measurements taken from 1965 to 1970 indicate two distinct periods of stage-discharge relationship (Table 6). The change has taken place during November and December 1968, where a break appears in the dailY averages. By using the Bugsoc runoff station and the Dagohoy rainfal1 station to calculate the missing records, it is possible to estimate annual and overall average runoff from the Pamacsalan station.

No active diversions could be traced upstream of the station except a dry riverbed taking out water for irrigation during floods. Therefore the station is considered to be areliable gauging site. The yield 44 1/sec/km2 is accepted as a representative ave rage figure for runoff from a small mountainous catchment in Central Bohol.

In connection with a planned irrigation project nearby Pamacsalan, the NIA has constructed a recording runoff station l km upstream of the WRB station. So far the observation period is very short and the station gives no valuable further information to this study. The station construetion itself is excellent.

Monthly flow statisties are shown in Figure 2.

LOW FLOW ANALYSIS

Reliability of recorded low flow very much depends on the local condition of flow control at each station, the quality of the rating, the ability of the hydrometrist to detect any changes of datum, and to be aware of the existence of any water-diverting structures upstream. The geology in Bohol, especially within the Bilar catchment causes the rivers to go dryearlier than expected, due to underground drainage.

The Tigbao and the Pamacsalan gauging stations are both considered acceptable concerning low flow records. The Bugsoc station suffers from diversions upstream, while Bilar at Owac occasionally ap­ proaches zero flow. Immediately upstream of the confluenee of Bilar and Loboc Rivers, the Bilar River is frequently observed dry. The absenee of grass in the riverbed indicates that water occasionally passes down the river.

Frequency analysis has been applied to annual minimum flows for all four gauging stations (Table 7). Flow duration curves has been drawn (Figures 4-7). 90% firm flow is taken from the duration curves. The result is displayed on Fig 8, where the Bugsoc station plots considerably lower than might be expected. The Owac station is dis­ regarded as not being representative of general conditions in Bohol.

One might interpret the curves as illustrating the incapability of a small mountainous catchment to retain water compared with the larger catchment. Loboc at Tigbao has a larger contribution from ground­ water during low flow conditions. The diagram shown on Figure 8 is an attempt to achieve a re1ationship for Central Bohol.

It should be stressed that the relationship is considered to re­ present catchrnents with ave rage extraction of water for irrigation as well as relatively little loss due to karst conditions. The number and location of gauging stations are far from satisfactory for the estimation of low flow at ungauged sites. The 10cal demand for irrigation water is not possible to prediet and depends very much on the distribution of rainfall in time and space during the low flow season. Therefore the value of the diagram is limited. To be able to estimate the miniurnum flow at various hydropower sites in Bohol, there is a pressing need for new gauging stations to be erected. Proposed new gauging stations are shown on Drawing 101, 121-123, 141-145.

Table 8 shows a few observations made at the end of a four week dry spell in Boho1. Disregarding the Bilar tributary of 226 km 2, the Janopo1 observation confirms the diagram. Wahig at Tipo10 carried far less water than expected. The reason is probably heavy use of water for irrigation in the area as indicated in information given by the Provincial Irrigation Engineer. The Abatan-Sinigan at Camugau still had a relative1y high runoff whi1e very little water appeared at Causwagan. No general conclusion regarding hydrological parameters can be drawn from these figures. Estimates made of low flow at various project sites are rather based upon spot observations than the general curve of Figure 8, for the upper central part of the province. 14

MEAN ANNUA L FLOW

Tigbao gauging station on Loboc River represents the hydrology typical for a cultivated region, while the Bugsoc and Pamacsalan stations in upper Wahig River demonstrate the high runoff from small mountainous catchments. Duration curves deduced are given in Figures 4 to 7.

The runoff at the Owac gauging station in Bi1ar River is heavily affected by the limestone formations. The recorded runoff from this catchment is substantia11y 10wer than shou1d be expected, c1early demonstrated by an occasiona11y dry river bed upstream of the conf1uence with the Loboc River. No human activities or vegetation within the Owac catchment can possib1y exp1ain such a low runoff. An expected yield of say 40 1/sec/km2 wou1d reduce the topographie catchment upstream by about 80%, leaving on1y 13 km 2 effective1y draining to Owac and 564 km 2 at Tigbao. Such a consideration would 15

raise the runoff at Tigbao from 31 1/sec/km2 to 34 1/sec/km2 • Pending the erection of runoff stations in the Janopol/Rizal area, 34 1/sec/km2 is adopted as representative for Loboc River at Tigbao.

A straight line log-log relationship between catchment area (km 2) and runoff (1/sec/km2) is established for the estimation of ave rage runoff at various sites in Central Bohol (Figure 8). The difference in runoff between Loboc and Upper Wahig is natural as ave rage rain­ fall is higher in the mountain range than over the plateau. Due to lack of more adequate gauging stations, the curve has to be considered indicative only. As demonstrated at Bugsoe, loeal conditions may cause the ave rage runoff to differ substantially from the curve estimation, especially in small catchments.

Another possibility is to consider a water balance, but this is not satisfactoryas the relationship between rainfall and runoff is too complex. Correlations between rainfall and runoff stations are very poor, both on monthly and annual basis, probably due to the sparse distribution of raingauges as well as the lack of more long term rainfall records. Judging from the Tigbao records, the existing rainfall records indicate an ave rage evapotranspiration of 900-1000 mm a year.

FLOOD STUDIES

Annual maximum of floods are published in the Water Resources Bulletins (l), and are summarised in Table 9. The figures are of varying quality, as they originate from different reeording procedures. Full details of the floods are not available, except for date, time, maximum water level and the corresponding flow. Judging from the time of observation, the bulk of "peak floods" recorded at Tigbao and Pamacsalan are taken from daily readings while highest floods published for the Bugsoc and Owac stations are events from different hours during daytime. No specific comments indicate whether the figures are based on water stage recorder, crest re­ corder, flood lines etc.

Large extrapolations were evidently made on the rating curves deri ved from the maximum measured discharges to arrive at rated peak flows (Table 10). Hence, taking into account the Bulletin remarks made on published reeords, the confidence in estimates of floods is very limi ted indeed.

The values in Table 9 were ranked in order of magnitude and plotted on Gumbel distribution paper using the Gringorton formula for the return period (Figure 9). Curves were fitted by eye from which the l/IDO-year peak floods as listed in Table 10 were derived. A logaritmic relationship between peak flood and catchment area is indicated in Figure 10. Considering the many possible sources of error already mentioned, an envelope curve has been drawn rather than the line of best fit. The Owac station plots well below the curve, which may be eaused by a shorter period of reeord. The overall use of the relationship should allow for considerable error of estimation, say ~ 50%. 16

AVAILABILITY OF WATER AT POSSIBLE PROJECT SITES

As outlined in previous sections, the number of good quality gauging stations is toe limited to allow the use of detailed hydrological methods for the estimation of hydrological parameters. The only possibility of estimating flows at ungauged sites at present the re­ fore is by using a simple relationship between flow and catchment size, thereby introducing a certain inaccuracy, especially concerning extreme flows. Design floods should allow for 50% error of estimation.

Pending records from adenser network of gauging stations, it is considered that the most representative duration curve is the one deduced from the Tigbao records, which is adopted for general use in this study. Some comments are necessary on individual projects. The need for additional gauging stations, particularly at proposed project sites can not be stressed too strongly (see Drawing 101, 121-123, 141-145).

Loboc River at Janopol

The major loss of water through underground drainage is assumed to take place in the Bilar catchment. It is not possible to pin-point the exact figure for the hydrological catchment area for the whole Bilar tributary. The previously mentioned 80 % correction of the Owac catchment corresponds to 24% correction of the total Bilar. Omitting Bilar completely is clearly not correct as water occasionally passes down the riverbed. The following table shows two extreme alternatives:

Correction Eff.catchm. Eff.catchm. Estimated Runoff of Bilar Bilar Janopol Janopol Janopol % km 2 km 2 1/sec/km2 m3/sec

24 171 411 33 13.6 80 45 284 35 9.9

The average annual runoff at Janopol therefore will be somewhere between 10 and 14 m3/sec.

The contribution of water during low flow is assumed to arrive from the northern 240 km 2 only. Using Figure 8 minimum flow (1/20 year return period) is estimated as 1.2 m3/sec, which is of the same order of magnitude as was observed after a 4 week dry spell in BahaI during May 1980. Firm flow is estimated as 2.4 m3/sec.

Floods are assumed to pass down all tributaries with relatively little loss of water due to karst drainage. Figure 10 indicates about 700 m3/sec for the 100 year flood. 18

Loboc River at Rizal

Despite the existence of extensive limestone formations within the 230 km 2 Rizal catchment, the adjacent gentle topography would allow only minor loss of water to take place along the catchment boundaries. Due to the intense irrigation activities in the Carmen area, the indicated minimum flows could prove somewhat optimistic during pronounced dry spelis. Considering the dry spell observation at Tipolo the minimum estimate has been reduced accordingly.

Wahig River at Tipolo

No karst problems are anticipated. Minimum flow can be estimated according to the spot observation.

Abatan-Sinigan River

It is expected that the river system is exposed to the same type of climate as the Loboc River.

As mentioned in previous sections, there is a trend of ave rage rainfall reducing from east to west with elevation. The fact that the established relationships between flow and catchment size represent eastern catchments mainly, demonstrates the ne ed for a gauging station to be erected in the Abatan-Sinigan River system.

Flow estimations using the relationship directly may lead to somewhat optimistic figures, as they would be biased by the Pamacsalan runoff where the average altitude is considerably higher. It is considered prudent, therefore, to adopt ave rage runoff comparable with the Tigbao catchment, i.e. 30-35 1/sec/km2 , approaching the lowest estimate towards south or extreme west.

Minimum flows are indications only, somewhat influenced by spot observations. Firm flows are estimated from the Tigbao dimention­ less duration curve.

Wahig River

See Drawing Nos. 101, 122 and 143.

National Irrigation Administration (NIA) has recently erected a new recording gauging station upstream of Pamacsalan. If the existing plans for a dam and diversion tunnel in this area is accomplished, the present gauging station near Pamacsalan will be recording only a fraction of the total catchment runoff. The Bugsoc gauging station is already affected by upstream channels diverting the water for irrigation purposes. This should altogether demonstrate the need for a gauging stat ion near the Tipolo project area.

An existing gauging station immediately upstream of the proposed in­ take site should be upgraded by a relocation of the station. The gauge needs a better flow control and more firm support of the gauge staff.

A suitable site is found about 100 m upstream of the proposed tunnel outlet. A crest recorder should be installed.

Abatan-Sinigan River

See Drawing Nos. 101, 123, 144 and 145.

There are today no runoff gauging station operating within the Abatan-Sinigan River catchment. Considering the assumptions already made in this report, conserning the catchment yield near the proposed Causwagan and Baunos project sites, the establishment of new gauging stations in the river system is of utmost importance.

Two sites are considered adequate. Site one is located near the proposed Causwagan weir site. A footbridge about 100 m upstream of the weir site would serve as a good support for a low flow gauge plate and a crest recorder.

Site two is located immediately downstream of a bridge about l.S km upstream of the proposed Baunos weir site. The bridge is partly broken down. As parts of the low flow control might be liable to scouring effects during floods, the rating should be checked by frequently taking discharges measurements.

Of the two sites, the first one has got a better flow control, as it is formed by rock bars in the river. Considering differences in catchments size and possible local underground drainage, both gauging stations should be established.

PROPOSED RIVER GAUGING STATIONS

See Drawing Nes. 101, 121-123, 141-145.

General

As stated previeusly, the numbers, quality and lecatien ef gauging statiens in Bohel teday is far frem satisfactery. An upgrading ef the existing gauging statiens wo.uld be useful but net sufficient. There is a pressing need fer new statiens te be erected in the near preximity ef the prepesed preject sites.

The Hydrelogical Field Recennaissance revealed the existence ef several acceptable sites fer new gauging statiens.

Lebec River at Janepel

See Drawing Nes. 101, 121 and 141.

The karst geelegy and pessible undergreund drainage in the area, requires the gauging statien te be lecated relatively clese te the actual preject site. A suitable centrel is feund abeut 200 m dewn­ stream ef the prepesed weir site. This part of the river censists ef rapids fellewed by a deep peel and a drep ef 2-3 m. The tep of the waterfall weuld serve as a good water level centrol during beth high and low flew conditiens.

The tepography ef the river banks seems faveurable fer a proper re­ cerder heusing te be censtructed. Still, an ordinary gauge plate read twice a day and supperted by crest recerder ebservatiens, weuld give adequate infermatien.

Lebec River at Rizal

See Drawing Nes. 101, 121 and 142.

Near the Rizal project the enly faveurable site fer a gauging statien is lecated 300-400 m upstream ef the prepesed weir site where a suit­ able lew flew centrol exists upstream of several censecutive rapids. During fleed perieds the water level at the gauge site is prebably controlled by hydraulic ebstructiens further dewnstream. There are ne suitable rocks nearby for recorder heusing suppert. The statien should therefore be designed as a multiple gauge plate statien, read twice a day. A crest recorder sheuld be installed.

Together with the propesed Janepol gauging statien the Rizal gauging statien weuld allew for a cleser study ef the contribution ef water frem the Bilar tributary, as well as more reliable recerds regarding the Lebec River catchment upstream of the junetion. 100 r-, 100 I I I I I I I I I I I I il Max.
