DATA USED AND METHOD INVOLVED
In order to understand the land use dynamics, Landsat and IRS series of data during 1973 to 2012 were analysed along with field data (collected using GPS) and other collateral information from the Survey of India topographic maps [37] (1: 250000, 1: 50000), revenue cadastral maps, French institute vegetation maps [38], India biodiversity portal [39], Google earth [40], Bhuvan [41] respectively. Land use analysis was carried out using the maximum likelihood classifier [42, 43, 44, 45, 46, 47, 48] Well water depths were monitored and stream flow (discharge measurements) was quantified using the area velocity method [31, 32, 49] in the select catchments to understand the water availability status in Sagara Taluk.
