Abstract

Human civilization has been colonizing land areas with an ample amount of water supply, good living conditions, accessibility, etc. since historical times. The proliferation of human activities since the industrial revolution has led to rapid urbanization and shrinkage of water bodies surrounding the cities. This is because of the siltation and blockade of major and minor recharge structures. One of the ways to assess the impact of colonization on the landscape is by using remotely sensed data. Manipal town in Udupi, Karnataka, India is one such landscape and Manipal lake is a reservoir present in Manipal affected by this. This study focusses on the assessment of land use and land cover (LULC) changes between the years 1995 and 2015, and its effects on lake surface area. We found out a significant decline in the surface area of Manipal lake. This study also includes reconstructing the natural landscape of the Manipal terrain by using a digital elevation model (DEM). DEM has delineated the hydrological features in the study area and extracted the natural drainage features of the terrain.
