Chapter-1 River Godavari and its Flood Problem

1.1 Godavari River System

The Godavari basin lies in the Deccan Plateau and is situated between 16o16’ N and 22o43’ N Latitude and 73o26’ E and 83o07’ E Longitude. It is roughly triangular in shape and the main river itself runs practically along the base of the triangle.

The river Godavari, the largest of the peninsular rivers, and the third largest in India, drains about 10% of India’s total geographical area. The catchment area of the river is 3,12,812 sq. km and is spread in the states of Maharashtra (48.6%), Telangana (18.5%), Andhra Pradesh(4.9%), Madhya Pradesh (10%), Chhattisgarh (10.9%), Odisha (5.7%) and Karnataka (1.4%).

The river Godavari rises at an elevation of 1,067 m in the Western Ghats near Triambak hills in the Nasik district of Maharashtra. After flowing for about 1,465 km generally in south-east direction, through Maharashtra, Telangana and Andhra Pradesh, it falls into Bay of Bengal. A line diagram of Godavari River is attached as Annexure-1.

The Godavari receives the waters of the Dharna on it’s right bank at downstream of Nasik town. Further down, river Kadwa joins near NMD Weir from the left. The combined waters of the Pravara and the Mula that rise in the hills of Aravali join the river from its right bank upstream of Jaikwadi Dam. In the Maharashtra state itself the river receives the combined waters from the Purna and Dudhna rivers. After crossing the border of Maharashtra the waters of the river Manjira joins it from right bank in Telangana. At this point, the Godavari flows at an elevation of about 329 m.

The river Pranhita, conveying the combined waters of Penganga, Wardha and Wainganga, which drain the southern slopes of the Satpura range, falls into Godavari at Kaleswaram about 306 km downstream of its confluence with the Manjira. About 48 km downstream from Kaleswaram the waters of the river Indrāvati join Godavari. Both the Pranhita and the Indrāvati are major rivers in their own right. The last major tributary is Sabari from Odisha that falls into Godavari about 100 km upstream of Rajahmundry.

The largest tributary of Godavari is the Pranhita with about 34.9% coverage of drainage area. The Pravara, Manjira and Maner are notable right bank tributaries covering about 16.1%, the Purna, Pranhita, Indrāvati and Sabari are important left bank tributaries, covering nearly 59.7% of the total catchment area of the basin. The

Godavari in the Upper, Middle and Lower reaches make up for the balance of 24.2%. The particulars of tributaries of the river Godavari are given in the following Table.

1.2 Physiography of the Basin

Except for the hills forming the ridge around the basin, the entire drainage basin of the river Godavari comprises rolling and undulating country, a series of ridges and valleys interspersed with low hill ranges. Except the delta area, the characteristics of the Indo-Gangetic plains i.e., large flat areas are scarce throughout the basin.

The western edge of the basin is almost an unbroken line of 129 km. formed by the Sahyadri range of the Western Ghats, forming a barrier of 600 to 2100 m height. It has the heaviest rainfall and the dampest climate in the basin. Hardly 50 to 60 km east of the Ghats lie the sparsely cultivated and undulating plains of the Deccan, with a dry climate.

The interior of the basin is a plateau, the greater part of which is at an elevation of 300 to 600 metre. Its general slope is eastwards, great undulating plains, divided from each other by flat topped ranges of hills, are the characteristics of this plateau.

2 | Page

The hillsides are marked by conspicuous wide terraces except in the southern parts where the hills are frequently crowned with great ‘tors’ or rounded hummocks of bare rock, the result of ages of weathering.

The northern boundary of the basin comprises a series of table-lands varying from 600 to 1200 metre in elevation, which have withstood the effects of ages of denudation better than the terrain to the north and south of them. To the south, lie great stretches of plain at an elevation of more than 300 m, interspersed with and surrounded by hill ranges, some bare and rocky, but generally covered with forests or scrub jungle.

The delta of the Godavari, formed by deposits at the mouth of the river over the ages, consists of a wide belt of river borne alluvium. The process of silting at the mouth of the river is still continuing and the delta is gradually extending into the sea.

1.3 Rainfall Pattern

The Godavari basin receives its maximum rainfall during the south-west monsoon. The monsoon currents strike the West Coast of the peninsula from the west and south-west, meet the Western Ghats or Sahyadri Range which present almost an uninterrupted barrier ranging from 600 m to 2100 m in height. Before surmounting this barrier the currents deposit most of their moisture on its windward side of Konkan and a small portion of Madhya Maharashtra, and then sweep across the interior of the peninsula on a south-westerly course. Rainfall is governed largely by the orography of the area, which leads to variation in the amount of precipitation. In crossing the Western Ghats, the monsoon winds lose a large part of their moisture. The monsoon currents follow the eastward slope of the country from the crest of the Western Ghats that form the watershed. Conditions in the interior are, therefore, somewhat unfavourable for heavy precipitation except in association with the depression from the Bay of Bengal. The north-east part of the Godavari basin also receives some rain in association with monsoon depressions, which move west-north-west across the Odisha coast.

The Western boundary of the Godavari River is about 129 km in length in the high rainfall zone in the Western Ghats. The annual rainfall is around 3,000 mm along this boundary and reduces rapidly to 1000 mm up to a line running approximately from Chitradurga through Sangli and Pune and east of this line it further reduces to less

3 | Page

than 600 mm up to a line connecting Rojapally tharda, Raichur, Vijayapura and Ahmednagar. East of this line the rainfall again gradually increases to about 900 mm towards the coast. There is an area of about 10,360 sq.km, including portions of the Aurangabad and Ahmednagar districts of Maharashtra which is having an annual rainfall of less than 600 mm. The area is lying 100 km East of the Western Ghats and in width varying from about 80 km in the South to about 97 km in the North.

The long-time annual average rainfall of the entire basin is about 1100 mm. January and February are almost entirely dry in the basin, the rainfall during these two months being less than 15 mm. During the next three months, up to end of May, the rainfall varies from 20 mm to about 50 mm, in most parts of the basin. All parts of the basin receive the maximum rainfall in the period from June to September. The entire Godavari basin is divided into twelve sub basins and the normal monsoon rainfall and number of rainy days (from 1st June to 30th September) of these sub basins is as follows:

S. Name of Sub Basin Normal Monson No. of No. Rainfall (mm) Rainy Days 1 Upper Godavari 777.4 40 2 Pravara 487.4 29 3 Purna 706.4 39 4 Manjira 846.1 44 5 Middle Godavari 996.6 49 6 Maneru 875.7 44 7 Penganga 910.8 45 8 Wardha 953.0 46 9 Wainganga 1182.0 52 10 Lower Godavari 1041.0 51 11 Indrāvati 1361.0 62 12 Sabari 1217 62 Average for the Entire Basin 946.3 47 Source: IMD

1.4 Flood problem:

During the monsoon, the Godavari River spills its banks in the Upper & Lower reaches at the confluence of rivers Indrāvati and Sabari with Godavari.

4 | Page

The parts of the basin lying in Odisha have generally no serious flood problem. The flooding of deltaic areas has been prevented by construction of embankments. However the stretch between Bhadrachalam to Rajahmundry are flood affected. The major flood prone areas of Godavari basin are shown in Annexure-2.

1.5 Importance of Flood Forecasting in Godavari Basin

Structural methods of Flood Control such as construction of reservoirs for storage of flood waters, improving the river channel to increase its flood carrying capacity and construction of embankments and levees are not always technically feasible and economically viable to control the floods. It has been recognized that loss of human life and property can be reduced to a great extent by giving reliable advance warning about the incoming floods.

In Godavari basin, embankments have been constructed to prevent the flooding of deltaic areas. However, considerably long reaches of the river upstream of the delta are vulnerable to floods. Scientific flood forecasting and advance warning have been found to be extremely beneficial to reduce the flood damages in these reaches.

Chapter-2 Flood Forecasting Activities in Godavari Basin

2.1 Flood Forecasting Activity

The present year 2018 is the 44th (forty fourth) year of operation of flood forecasting activities in Godavari basin. Flood forecasting activity in the basin started in 1974 with the opening of a Division office of Central Water Commission at Pochampad (Sriramsagar Dam). In 1975 the office was shifted to Hyderabad for better management and communications. Initially, stage forecasts were issued for Dowlaiswaram Anicut (Sir Arthur Cotton Barrage) for the monsoon 1975. Presently, stage forecasts are issued on regular basis for 14 (fourteen) stations located on the main Godavari and its tributaries. Inflow forecasts are also issued for the 4 (four) reservoirs viz., Jaikwadi and Sriramsagar on the main Godavari & Singur and Nizamsagar on river Manjira. In addition, 3 level forecast and 3 inflow forecast stations are taken up in the XII plan scheme. Further, 15 inflow forecast stations are proposed to be taken up by 2020. The list of flood forecasting stations and the flood forecasting network are given in the Statement-1 and in Annexure-3 respectively.

River stage forecasts and advance warnings enable the concerned authorities to take up appropriate precautionary measures to minimize the loss of life and property. Reservoir inflow forecasts help in better reservoir regulation.

2.2 Present Organisational Setup

To facilitate the forecasting of floods, the Central Water Commission has established a network of river gauge, discharge and rainfall stations in Godavari basin. The administrative management of these stations is divided among three divisions, namely Lower Godavari Division, Upper Godavari Division and Wainganga Division. The Lower Godavari Division and Upper Godavari Division with the headquarters at Hyderabad function under the control of Superintending Engineer, Godavari Circle, Hyderabad within the organizational jurisdiction of Chief Engineer, Krishna & Godavari Basin, Hyderabad. The Wainganga Division with the headquarters at Nagpur functions under the control of the Superintending Engineer (Co-ordination), Nagpur within the organizational jurisdiction of the Chief Engineer (Monitoring - Central), Nagpur. The present organizational set-up in Godavari basin is shown in Annexure-4.

2.3 Data Collection Network

Central Water Commission is having a vast network of Hydrological Observation sites (Gauge, Discharge and Rainfall stations) throughout the Godavari basin. The

6 | Page

network of these stations transmit the data collected on real-time basis to the flood forecasting centre at the Lower Godavari Division, Hyderabad using high frequency (HF) wireless sets. The list of hydrological observation stations connected by wireless network and the schematic diagram of data communication network in the basin are given in the Statement-2 and in Annexure-5 respectively.

The river gauge is observed at every hour on all days in monsoon from 1st June to 31st October whereas the discharge is observed once in a day. The river gauges at the gauging stations are connected to GTS benchmark.

Rainfall is observed normally twice in a day during the flood season at all the rain gauges maintained by Central Water Commission. In addition, Flood Meteorological Office of the India Meteorological Department, Hyderabad supplies rainfall data, the daily weather situation, the Quantitative Precipitation Forecast (QPF) and the outlook for subsequent two days.

As part of modernisation Central Water Commission has established a network of telemetry stations in the basin for collecting real time data of water level and rainfall. The list and map of existing Telemetry stations installed in the basin are shown in Statement-3 and Annexure-6 respectively.

2.4 Methodology adopted for Flood Forecast Formulation

The flood forecasts are formulated as per the procedure given in the “Manual on Flood Forecasting” brought out by Central Water Commission for both stage and inflow forecasts. They are formulated using conventional method as well as the advanced rainfall run-off conceptual modelling techniques. The conventional method uses the past data of river stages to draw a correlation diagram between the levels at the base station and the levels at the forecasting station. Correlation diagrams are of two types, viz., simple correlation and multiple correlation.

2.4.1 Simple Correlation

This is the simplest of all types of correlations in which a correlation between Nth hour stage of base station and (N+T)th hour stage of forecasting station (where T is the travel time) is developed using historical data. This type of correlation gives a rough estimate of the peak level likely to be attained. For simple correlation, a linear equation is normally adopted which of the form:

7 | Page

y= mx + C where y is the (N+T)th hour stage at forecasting station x is the Nth hour stage at base station m and C are constants.

This type of correlation graph can be developed and used for such type of reaches of the river where:

i. No major tributary with considerable discharge joining the main river in the intervening catchment, ii. The intervening catchment area is comparatively less i.e., the effect of intermediate rainfall is negligible, iii. The travel time from the base station to the forecasting station is fairly constant for various stages.

The following graph shows a simple correlation between the levels at base station at Nth hour and at forecast station at (N+T)th hour.

When this correlation curve is not adequate in giving an accurate flood forecast, more factors are to be considered by using multiple correlation curves.

8 | Page

2.4.2 Multiple Correlation

The relationship obtained from simple correlation can be improved by considering the following additional factors and adopting multiple correlation techniques.

i. Varying conditions during rising and falling stage of the flood, ii. Intermediate rainfall in the catchment and iii. Downstream boundary condition.

In the following figure, the first quadrant represents the rising and falling stages of base station. The second quadrant represents the intermediate rainfall in the catchment whereas the third quadrant represents the intermediate catchment contributions.

Fig. 2 Multiple Correlation Diagram for Flood Forecast Formulation at Bhadrachalam

Varying Condition during Rising and Falling Stages In the first quadrant of correlation diagram, the variation of the gauge at base station during the preceding time interval equal to travel time from base station to forecast station is correlated with the variation of the gauge in the forecasting station. For drawing this curve hourly data of base station and the forecasting station for various number of peaks have to be taken and based on the travel time during these levels, the variations at base station have to be found out. Similarly the variations at

9 | Page forecasting station are also to be found out. A set of lines for various gauge differences in the base and the corresponding variation in the forecasting station have to be drawn in the best fit method. Two different sets of lines, one for the rising limb and another for the falling limb can be plotted for various gauge differences. This is the first quadrant correlation curve which basically considers the gauge level only at the base and forecasting stations and gives an approximately good forecast if other effects such as intermediate rainfall or contribution from major tributary are negligible.

Intermediate Rainfall in the Catchment

In order to account for rainfall in the intermediate catchment, the first quadrant correlation curve has to be updated with the likely rise due to the rainfall in the intermediate catchment. The rainfall observations in and around the basin at various points provide the ‘point rainfall’ at respective points. For all practical purposes the Mean Areal rainfall falling over the entire intervening catchment of the basin is required.

The mean areal rainfall in the catchment area is used in the second quadrant of the correlation curve by finding out the increase in water level at the forecasting station for various mean areal rainfall over the catchment. From the second quadrant the contribution from rainfall adds to the forecast already formulated from the first quadrant. This is a qualitative improvement to the forecast. When there is no tributary between the base and forecasting station, the second quadrant correlation curve almost gives an accurate forecast.

Effect of Major Tributary on the Main River

If a tributary joins the main river in between the base and forecasting station, then the contribution from that tributary will be taken into account in the third quadrant of the correlation curve. If a gauge station is existing on the tributary, the travel time from the station to the forecasting station is found out and the variation in the gauge at the gauge station and forecast station during the travel time is correlated and sets of lines for both rising and falling limbs are drawn. If a reservoir also located in the tributary and if it releases water then that contribution has also to be found out by using the Stage Vs Discharge curve of the station. Thus a multiple correlation curve takes into effect all the probable variations in the parameters for issuing an accurate forecast.

10 | Page

Additional parameters are also used to cover uncertainties in local conditions as well as for local rainfall pattern and intensities and a final forecasted stage can be obtained for various conditions. The travel time from base station to forecast station is to be obtained from the travel time curve.

2.4.3 Travel Time Curve

The time taken by a flood peak to travel from the base station to the forecasting station is called as the Travel Time of the flood wave. It varies depending on the river stage. During high stages travel time from base station to forecast station may reduce/ increase substantially depending on the flood water whether the river is within the river section or spilling into the flood plains. In order to account for these variations a travel time curve has to be drawn with the peak value of water level in Y- axis and the time taken to reach the forecast station in X-axis. For various peaks different points have to be marked and a curve ‘best fit’ has to be drawn based on these points. From this curve the travel time for various stages in base station can be found out.

The forecasts are formulated and issued in the morning and evening hours every day as long as the water level remains above warning level. The forecasts are issued by giving a warning time of about 12 to 24 hours depending on the Travel Time available. Revisions are made, whenever necessary, at any later time depending on the changes in the pattern of the parameters.

2.5 Dissemination of Forecasts

Flood forecasts are formulated whenever the water level in the river touches or crosses the Warning Level fixed for that particular flood forecasting station. These forecasts are transmitted by wireless, telephone, special messenger or by a combination of above modes promptly to the flood control room set up by State Government, District authorities and other user agencies. The Danger and the Warning Levels are fixed by the user agencies considering aspects of flood loss. In case of Inflow forecasts for the reservoirs, forecasts are issued once in 24 hours in advance uniformly and whenever the inflows into the reservoir exceeds 1000 cumecs.

Since forecast stations near the East coast sometimes get affected by floods on account of the depressions and cyclones, originating in the Bay of Bengal, especially

11 | Page in the months of May and November, the staff are kept alert and special forecast bulletins are issued on such occasions whenever situation warrants.

In addition to the District Collectors concerned, local officials of the district administration are also directly informed about the flood for enabling them to take up appropriate measures to mitigate the flood losses. The information is conveyed to the State flood control room at Hyderabad for further communication to the Chief Secretary, Commissioner of Relief, Engineer-in-Chief of Irrigation Department and other officers of the State Government. The information is also passed on to the nearest A.I.R. stations, Television and local press for reaching out to large populace who are directly affected by the floods. The list of user agencies to whom the forecast messages are issued are given in Statement-4.

Chapter-3 Southwest Monsoon 2018

3.1 Advancement of Southwest Monsoon 2018

In Godavari basin, the flood occurs mainly due to southwest monsoon which is spread from June to October of every year. In this year, the southwest monsoon sets in Kerala on 29th May 2018 and covered the entire Godavari basin by 14th June 2018. The progress of southwest monsoon-2018 is shown in Fig.3 (Source: IMD).

Fig. 3 Progress of Southwest Monsoon 2018 (Source: IMD)

3.2 Rainfall in Monsoon 2018

Low pressure areas created in Bay of Bengal turned into Depression and moved north-westwards along the monsoon-trough and helped to maintain the monsoon activity over the region. In this year, normal to heavy rainfall were observed throughout the basin. Flood waves were not observed in upper reaches of Godavari. Heavy flood occurred in Indrāvati Basin and lower reaches of the basin.

From the network of Hydrological Observation sites (Gauge, Discharge and Rainfall stations) throughout the Godavari basin the meteorological data has been

13 | Page

received from all the existing sites under the basin. The list of daily rainfall occurrences greater than 50 mm at all stations under Godavari basin given in Statement-5.

In addition, India Meteorological Department, Hyderabad provides meteorological inputs such as rainfall data, Quantitative Precipitation Forecast (QPF) and synoptic situation to this division through email every day through its Flood Meteorological Office (FMO) wing. IMD provides QPF to 12 sub-basins viz., Upper Godavari, Pravara, Purna, Manjira, Maneru, Middle Godavari, Wainganga, Wardha, Penganga Indrāvati, Lower Godavari and Sabari of Godavari Basin. The deviation in the actual rainfall during monsoon 2018 w.r.t normal monsoon rainfall is shown in the following table.

Normal RF Actual RF % S.No. Name of Sub Basin in mm in mm Deviation 1 Upper Godavari 777.4 499.9 -35.7 2 Pravara 487.4 326.1 -33.1 3 Purna 706.4 583.5 -17.4 4 Manjira 846.1 573.7 -32.2 5 Middle Godavari 996.6 951.8 -4.5 6 Maneru 875.7 765.4 -12.6 7 Penganga 910.8 938.1 3 8 Wardha 953.0 882.5 -7.4 9 Wainganga 1182.0 1135.9 -3.9 10 Lower Godavari 1041.0 1006.6 -3.3 11 Indrāvati 1361.0 1439.9 5.8 12 Sabari 1217.0 1448.2 19 Average for the Entire Basin 946.3 879.3 -10.2 Source: IMD, Hyderabad

From the above table it is inferred that, during this year least amount of rainfall occurred in upper reaches of Godavari, near normal rainfall occurred in middle Godavari and near above normal rainfall occurred in Sabari and Indrāvati basins.

3.3 Flood events during the flood season 2018

In the year 2018, floods occurred in Godavari basin at two inflow forecasting stations viz., Jaikwadi Dam, Sriramsagar Dam and at six level forecasting stations viz., Jagdalpur, Eturunagaram, Dummugudem, Bhadrachalam, Kunavaram and Dowlaiswaram. The basin wise floods occurred in 2018 are discussed separately in the coming chapters where the peak level attained and the period in which the stage remained above Warning / Danger Level, within + 0.5 m of Highest Flood Level (HFL) and above previous HFL in each of the flood forecast station are given.

Chapter-5 Forecast Performance in 2018 and its Improvements and Modernisation

5.1 Forecast Performance

Forecasts will be issued regularly for the water level of river at all the forecast stations whenever the water level is likely to cross the warning level. Advisory forecasts will be issued whenever the water level is likely to reach the warning level. This year a total of 68 forecasts were issued for eight forecasting stations, out of which 62 forecasts were within the acceptable limits (±15 cm for level forecasting and ±20% for the inflow forecasting), resulting a 91% accuracy. Bar diagram of forecasts issued and number of forecasts within the acceptable limits for each forecast station during the year 2018 is given in Fig. 9. Bar graph showing the year wise forecast performance from 1975 to 2018 is given in Fig. 10.

5.2 Improvements to Flood Forecasting

Flood forecasting techniques are constantly reviewed and updated to make the forecasts more reliable. The correlation curves of forecast stations are updated at the end of every year taking the data of the present year also into consideration.

5.3 Modernisation of Flood Forecasting System

Under the X Plan scheme “Establishment and Modernisation of flood forecasting including inflow forecasting”, 63 telemetry stations were installed under Godavari basin. Subsequently another 35 stations are also established to strengthen the real time data collection network. However, the data is to be streamlined for using the same in forecasting which is under process. Further, there is a proposal to extend the telemetry network to cater for the proposed forecasting stations in Godavari basin.

31 | Page

5.4 Use of Internet in Flood Forecasting

Internet is being used in the flood forecasting of Godavari basin since 2014. The Hydro-metrological data (Water Level, Discharge & Rainfall is updating continuously in the e-SWIS portal (online web site of CWC) and the same can be seen by the users. Data received from the three Divisions i.e., Lower Godavari Division, Upper Godavari Division & Wainganga Division are entering in the e-SWIS. The daily flood bulletins and the forecasts if required are prepared and sent to all the concerned by SMS / e-mail on real time basis. The weather situation, rainfall and the QPF etc., of IMD which are utilized extensively in flood forecasting are receiving daily through emails only.

5.5 Three day’s Advance Forecast online model

CWC (HQs), New Delhi has developed basin wise mathematical models for all 19 river basins of India for providing 3 days flood forecasts. The satellite real-time rainfall data as well as QPF issued by IMD is being used to generate flood forecasting at 240 stations all over India. The input and output of the model can be seen at 120.57.32.251. Efforts are being made to fine-tune the model and improve the accuracy of the model generated forecast also.

5.6 Difficulties and Bottlenecks in flood forecasting

The flood forecasting is not going to be an easy task in basins such as Godavari having vast tributaries along its course and where the rainfall in the intervening catchment area between the base station and the forecast station can itself generate a huge flood which can rise the stages beyond the warning level rapidly. There should be a more number of real-time reporting rain gauges. For this purpose, the State Government authorities which are looking after the relief and rescue operations, should make arrangements to pass on the real - time rainfall data at least twice in a day to the nearest CWC control rooms so that effective forecasting can be done.

5.7 Hourly Gauge Variation above Warning Level during Flood Waves

The Performance Criteria of within ± 15 cm is not realistic for Godavari basin. The rise and fall per hour is as high as 50 cm at some of the stations under the basin. Even the average rise and fall per hour is around 8-10 cm at many of the forecasting

32 | Page

stations. Therefore, there is a need to revise the criteria for the performance of forecasting in Godavari basin. It is felt that the criteria may be in comparison with its maximum rise/fall during flood waves.

5.8 Suggestions for improvement

The following suggestions may be considered for improvement of flood forecasting network and its usefulness to the general public as well as to the user agencies.

1. Central Water Commission issues flood forecast for level as well as inflow at specified locations in the river Godavari and its tributaries. It was seen that the information of sudden releases from several projects in Madhya Pradesh, Maharashtra, Telangana and Andhra Pradesh due to very heavy point rainfall, breaches in tanks were not informed immediately to the nearest CWC offices / Control Rooms by the concerned State Governments making it difficult for the revision / modification of a forecast issued already.

2. During monsoon season, the State Governments should share all the related hydro-meteorological data available with them on real time basis with CWC.

5.9 Future Proposals

At present level forecast at 14 stations and inflow forecast at 4 reservoirs are being issued in Godavari basin. Necessary data collection and development of mathematical model are under progress for issuing forecast at additional 6 stations (viz., Chinturu, Atreyapuram, Sirpur, Kaddam, Indirasagar Polavaram and P V Narsimha Rao Kanthanapally) in the basin. CWC is also planning to extend the telemetry network in Godavari basin to strengthen the real time data collection and initiate flood forecasting activities at 14 stations by 2020.
