    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.

The author assumes that the old ridges in Stage I at Sembulailarna, Kiriyanl(ailiya, Pambala, Wiraliena, Uluambalarna and Kadrana areas have been fonned precedng the Holocene transgression. Low hMs and ridges in the area were coated mainly by wind blown sand, fonowing the lower sea levels during the Late Pleistocene and Earty Holocene Epochs. Radiocarbon datings en the west and seuth coast$ reveal that the sea level remained 1rn or more above the present sea level between 6170± 70 and 535e± 80 yr B. P. During this transgression, the forTner drainage basins were submerged and headland bay beaches were ereated. Many wetlands aiid beach ridges, particularly in Stages ll, III, and IV were gradualy formed owing to rninor oscMations of sea levet after mid-Holocene. Most of these landiorTns haveaclose relationship with main climatic zenes of the country. 1987; Katupotha, 1988) also help to deterrnine their I. Introduction evolution.

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.

  • Sovereignty Vs. Trans-Boundary Environmental Harm: the Evolving International Law Obligations and the Sethusamuduram Ship Channel Project
    Sovereignty vs. trans-boundary environmental harm: The evolving International law obligations and the Sethusamuduram Ship Channel Project Chinthaka Mendis - United Nations / Nippon Foundation Fellow 2006 1 Acknowledgements The present paper address a topic, which has recently experienced an explosion of new developments and gained enormous importance to small developing nations like Sri Lanka. It has enabled States that may be affected by environmentally degrading activities of other States to take safeguard actions in a successful manner. Furthermore this evolving new law of international responsibility attempts to strike a careful balance between international environmental protection and the principle of territorial sovereignty. This is a very interesting and thought provoking area of research and to my humble delight my supervisors Professor Betsy Baker of Harvard Law School and Dr. Francois Bailet of UN Division for Ocean Affairs and the Law of the Sea responded with great enthusiasm. I sincerely say that I am deeply indebted to both of them for their valuable review of my work and the great support extended to me in performing my task. In fact my interesting tenure at the Harvard Law School and DOALOS, as a United Nations/Nippon Fellow allowed me to refine my knowledge of international law and become better acquainted with this evolving international system. Thus, the Division for Ocean Affairs and the Law of the Sea, Office of Legal Affairs, United Nations and the Nippon Foundation of Japan richly deserve my most appreciative thanks for their cooperation in the establishment of this rewarding fellowship programme.

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 .

Water bodies present in Urban Contexts has been a primary determinant force in the urban formation and settlement patterns. With the evolutionary patterns governing the cities, the presence of water bodies has been a primary generator bias, thus being a primary contributor to the character of the city and the urban morphology. Urban form can be perceived as the pattern in which the city is formed where the street patterns and nodes are created, and the 03 dimensional built forms, which holistically forms the urban landscape. The perception of urban form has also been a key factor in the human response to the built massing, and fabric whereby the activity pattern is derived, with the sociological implications.
