Abstract No: 11 Earth and Environmental Sciences
Proceedings of the Postgraduate Institute of Science Research Congress, Sri Lanka: 26th - 28th November 2020 Abstract No: 11 Earth and Environmental Sciences PRIORITIZATION OF WATERSHEDS IN UVA PROVINCE, SRI LANKA, BASED ON SOIL EROSION HAZARD I.D.U.H. Piyathilake1*, R.G.I. Sumudumali1, E.P.N. Udayakumara2, L.V. Ranaweera2, J.M.C.K. Jayawardana2 and S.K. Gunatilake2 1Faculty of Graduate Studies, Sabaragamuwa University of Sri Lanka, Belihuloya, Sri Lanka 2Department of Natural Resources, Sabaragamuwa University of Sri Lanka, Belihuloya, Sri Lanka *[email protected] Uva Province in Sri Lanka is most significant in terms of its hydrological contributions since it consists of ten major river basins including source areas of three tributaries of Mahaweli River. The Province is affected by human-induced soil erosion by water. Hence, identification of soil erosion hazards and prioritizing them based on watersheds are crucial for improving soil conservation and water management plans. This study assessed the mean annual soil loss from the Province and watersheds separately using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) Sediment Delivery Ratio (SDR) model introduced by the Stanford University, USA, using ArcGIS 10.4 environment. To cover the spatial extent of the Uva Province, the raster maps of Digital Elevation Model (DEM), rainfall erosivity factor (R), soil erodibility factor (K), and land use land cover (LULC) maps were prepared using ArcGIS 10.4. A biophysical table was formulated as a .csv (Comma Separated Value) table containing crop management (C) and support practice (P) factors corresponding to each land use classes in the LULC raster. -

Fit.* IRRIGATION and MULTI-PURPOSE DEVELOPMENT
fit.* The Historic Jaya Ganga — built by King Dbatustna in tbi <>tb century AD to carry the waters of the Kala Wewa to the ancient city tanks of Anuradbapura, 57 miles away, while feeding a number of village tanks in its course. This channel is also famous for the gentle gradient of 6 ins. per mile for the first I7 miles and an average of 1 //. per mile throughout its length. Both tbeKalawewa andtbefiya Garga were restored in 1885 — 18 8 8 by the British, but not to their fullest capacities. New under the Mabaweli Diversion project, the Kill Wewa his been augmented and the Jaya Gingi improved to carry 1000 cusecs of water. The history of our country dates back to the 6th century B.C. When the legendary Vijaya landed in L->nka, he is believed to have found an island occupied by certain tribes who had already developed a rudimentary sys tem of irrigation. Tradition has it that Kuveni was spinning cotton on the bund of a small lake which was presumably part of this ancient system. The development of an ancient civilization which was entirely depen dent on an irrigation system that grew in size and complexity through the years is described in our written history. Many examples are available which demonstrate this systematic development of water and land re sources throughout the so-called dry zone of our country over very long periods of time. The development of a water supply and irrigation system around the city of Anuradhapuia may be taken as an example. -

An Assessment of the Water Quality in Major Streams of the Madu Ganga Catchment and Pollution Loads Draining Into the Madu Ganga from Its Own Catchment
An assessment of the water quality in major streams of the Madu Ganga catchment and pollution loads draining into the Madu Ganga from its own catchment A.A.D. Amarathunga* and N. Sureshkumar National Aquatic Resources Research and Development Agency (NARA), Crow Island, Colombo 15, Sri Lanka. Abstract The Madu Ganga Lagoon is located in the Southern Coast, Northwest of the city of Galle within the Galle District. The aim of this study was to evaluate the pollution status of the lagoon and the contribution of the land base pollutants from the catchment of the Madu Ganga. Selected water quality parameters were measured at monthly intervals at twelve sampling locations in the catchment. Certain parameters such as salinity (2.2 + 1.7 ppt), oil & grease (8.5 + 6.5 mg/L), total suspended solids (16.1 ± 12.3 mg/L), and turbidity (20.1 ± 12.5 NTU) are found to be elevated levels when compared with water quality standards. The study revealed that the Lenagala Ela brought a high nutrient load (426.7 kg/day) into Madu Ganga and Arawavilla Ela, Magala Ela and Bogaha Ela also contributed significantly. The highest nutrient loads were found with the onset of the Northeast Monsoon during November to January. The increase in nutrient loads is attributed to the fertilizers added to the soil with the commencement of the major paddy cultivation season.

The year under review was eventful and we were able to take many progressive steps that will steer this sector to be more productive to serve the nation in the coming years. The capital investment programme of the Ministry had a workload of approximately Rs 20,000 million. This was a heavy development programme. We were on the path to achieve good progress, in spite of floods occurred in the beginning of the year and other constraints that had to be overcome during implementation. Steps were taken to remedy constraints such as staff shortages that existed, by new recruitments to the certain skilled technical grades but the shortage still prevails by large especially in the grades of Engineers, Engineering Assistants and other technical categories, which is being addressed by way of restructuring institutions, reviewing schemes of recruitments etc. -

A synopsis of a series of national, provincial and local level dialogues on unregulated / illicit river sand mining Compiled by Ranjith Ratnayake Sri Lanka Water Partnership November 2008 River Sand Mining (Manual) Sand Removal from River Bed RIVER SAND BOON OR BANE? Preface Unregulated and illicit River Sand Mining (RSM) and its consequences with the related aspect of corruption, has been an issue that has constantly come up for discussion at forums organized by the Sri Lanka Water Partnership (SLWP) on Integrated Water Resources Management (IWRM) and other water related topics, starting with a Gender and Water dialogue held in Kurunegala in 2005. Two of the Area Water Partnerships (AWP) established for Deduru Oya (Deduru Oya Surakeeme Sanvidhanaya ) and the Maha Oya (Maha Oya Mithuro) have this as the priority issue, whilst three other AWP for Malwatu Oya , Upper Mahaveli and Nilwala highlight sand mining as needing urgent resolution. The SLWP after several local discussions organized a National Dialogue on River Sand and Clay Mining on 24th April 2006 in Colombo in collaboration with the Capacity Development Network (CapNet ) and the Network of Women Water Professionals ( NetWwater). The Hon; Minister of Science and Technology who was Chief Guest at this workshop attended by the relevant agencies and NGO agreed to set up a Ministerial Task Force for technological alternatives to river sand to be considered . -

Blatner, Ph.D., Chair ___________________________________ C. Richard Shumway, Ph.D. ___________________________________ Jill J. McCluskey, Ph.D. ii ACKNOWLEDGMENT Earning a PhD from WSU fulfills a long held aspiration in my life to earn a doctorate from a US university. I thank all those who have contributed to my achieving this goal at Washington State University. Frank Rijsberman, Director General (2001-2007) of the International Water Management Institute (IWWI), was the key person behind meeting my aspiration to earn a PhD. His vision and passion for capacity building of scientific manpower in the South led to the initiation of the IWMI’s program for capacity building that supported my dissertation research. Frank also authorized the initial support for my PhD program. I thank Frank’s successor Colin Chartres, and David Molden, Interim Director General for continued support to me. At WSU, my major professor Keith Blatner was the key person behind fulfilling my goals. In addition to his unmatched knowledge spanning across many disciplines, Keith was a constant source of support and I also appreciate his compassion and empathy. I thank Richard Shumway for helping me fulfill my academic aspirations at a very high level.
