Hydrological maps as a tool for the exploration of historical water systems at Badami, Karnataka, India

The present study uses Remote Sensing imagery to identify water features and digital elevation model to generate hydrology maps (catchment and stream maps) and demonstrates the role of historical water harvesting systems in this landscape. The use of hydrology maps has enabled recognising the significance of the seemingly mundane looking, lesser-known small water harvesting structures that dot the landscape, which have sustained the millennium-old reservoir.
