21-Hydrological status of a few tanks in Mysore - A study using GIS & remote sensing

Abstract

Urbanisation is both a boon and a bane to the tanks. Hence, if managed well, urban tanks can be made to serve the purposes they are intended to better than they do under the normal conditions. Six tanks in Mysore have been studied in the present study, to understand ways to manage them better. The land use and the urbanization pattern in the catchment of these tanks have been determined through image processing. Availability of runoff and sewage in the area is determined. The present status of the quality of water in the tanks is analysed. The quantity of sewage needed to be diverted into the tanks is estimated and the treatment needed to be given is suggested.
