  • Anthropogenic Impacts on Urban Coastal Lagoons in the Western and North-Western Coastal Zones of Sri Lanka
    1 2 Anthropogenic Impacts on Urban Coastal Lagoons in the Western and North-western Coastal Zones of Sri Lanka Jinadasa Katupotha Department of Geography, University of Sri Jayewardenepura Gangodawila, Nugegoda 10250, Sri Lanka [email protected] Abstract Six lagoons from Negombo to Puttalam, along the Western and North Western coast of Sri Lanka, show signs of some change due to urbanization-related anthropological activities. Identified activities have direct implications on morphological features of lagoons, elimination of wetlands (mangrove swamps and marshy lands) and pasture lands, land degradation due to encroachment for shrimp farms, shrinking of lagoons, and production of higher nutrient and heavy metal loads, decline in bird and fish populations and degradation of the scenic beauty. As a result, the lagoon ecosystems have suffered to such a degree that numerous faunal and floral species have disappeared or have diminished considerably over the last few years. All these anthropogenic impacts were identified by the author during 1992, 2002, and 2006 as well as in a study on “Lagoons in Sri Lanka” conducted by IWMI between 2011 and 2012. Key words: Anthropogenic Impacts, Urban Coastal Lagoons, Garbage accumulation, Awareness program Introduction The island of Sri Lanka has 82 coastal lagoons that support a variety of plants and animals, and the economy [1]. Anthropogenic impacts, particularly lagoon fishing, human occupation of the land and water contamination have considerably reduced the faunal and floral population to a point that some of them are in danger of extinction. Such danger of extinction has been accelerated in urban lagoons of the western and northwestern coastal zones, e.g.

  • 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.

  • Evolutionof Coastallaridformsinthe Western Part of Srilanka
    HiroshimaHiroshimaGeographicalAssociation Geographical Association Geographical Sciences vol, 43 no.1 pp, 18-36, 1988 Evolution of Coastal Laridforms inthe Western Part of Sri Lanka JINADASA KATUPOTHA* Key Words:evolution of coastal landforms, SriLanka, late Pleistocene, Holocene, landfOmi classMcation Abstract Geomorphic and geologic evidence shows four different stages {Stage I-IV} in the evolution of coastal landforrns on the west coast of Sri Lanka during the Iate Pleistocene and Holocene Epochs. 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.

  • Precipitation Trends in the Kalu Ganga Basin in Sri Lanka
    January 2009 PRECIPITATION TRENDS IN THE KALU GANGA BASIN IN SRI LANKA A.D.Ampitiyawatta1, Shenglian Guo2 ABSTRACT Kalu Ganga basin is one of the most important river basins in Sri Lanka which receives very high rainfalls and has higher discharges. Due to its hydrological and topographical characteristics, the lower flood plain suffers from frequent floods and it affects socio- economic profile greatly. During the past several years, many researchers have investigated climatic changes of main river basins of the country, but no studies have been done on climatic changes in Kalu Ganga basin. Therefore, the objective of this study was to investigate precipitation trends in Kalu Ganga basin. Annual and monthly precipitation trends were detected with Mann-Kendall statistical test. Negative trends of annual precipitation were found in all the analyzed rainfall gauging stations. As an average, -0.98 trend with the annual rainfall reduction of 12.03 mm/year was found. April and August were observed to have strong decreasing trends. July and November displayed strong increasing trends. In conclusion, whole the Kalu Ganga basin has a decreasing trend of annual precipitation and it is clear that slight climatic changes may have affected the magnitude and timing of the precipitation within the study area Key words: Kalu Ganga basin, precipitation, trend, Mann-Kendall statistical test. INTRODUCTION since the lower flood plain of Kalu Ganga is densely populated and it is a potential Kalu Ganga basin is the second largest area for rice production. During the past river basin in Sri Lanka covering 2766 km2 several years, attention has been paid to and much of the catchment is located in study on precipitation changes of main the highest rainfall area of the country, river basins of Sri Lanka.

  • Development of a Flood Forecasting Model for Kalu River and Kelani River Basins in Sri Lanka Using Radial Basis Function Neural Networks
    Development of a Flood Forecasting Model For Kalu River and Kelani River Basins in Sri Lanka using Radial Basis Function Neural Networks Seenipellage Chaminda Sugeeswara Supervisor: Prof. A. W. Jayawardena MEE09208 Abstract This research is intended to investigate a kind of river stage/discharge forecasting model suitable for Sri Lankan flood prone rivers as an essential component of an effective early flood warning system. This work was carried out on a belief, that data driven river stage/discharge model would be more suitable for Sri Lankan rivers as there are considerable amount of past records of data while other physical information that are required to develop physically based models are rare. Artificial neural networks (ANN) have recently become popular in many fields including river stage/discharge forecasting in hydrology. Among various types of ANNs, radial basis function networks (RBFN) are popular over the more widely used multilayer perceptrone for its faster convergence, smaller extrapolation errors and higher reliability. In this study, generalized radial basis function network (GRBFN) with fully supervised algorithm (trained using daily data) was applied to two most flood prone river basins for forecasting one day ahead discharge at two respective river gauging stations. Upper Kalu River basin with smaller catchment area and smaller catchment response time did not show good forecasting results, but Kelani River catchment with comparatively large catchment area, with a response time of almost a day, showed good forecasting results. It was concluded that the GRBFN could be successfully applied to daily river stage/discharge forecasting for comparatively lager catchments with larger response time (close to a day).
