Impacts of land cover dynamics and shallow groundwater abstraction on sustainability of Hakwatuna Oya irrigation system
2016
Tropical Agricultural Research
Deforestation, expansion of agriculture and over abstraction of groundwater in watersheds can influence the water yield. Hakwatuna Oya watershed area in Deduru Oya basin also faces a similar situation due to rapid land use/cover changes and associated impacts. This study was conducted to identify the land use change dynamics and their possible impacts on the inflow to the Hakwatuna Oya reservoir. Land use mapping was done using 1:50,000 topographic maps and Landsat TM, ETM+ and OLI satellite
