In present study, potential sites for construction of rainwater harvesting structures in Morna river catchment of Satara District, Maharashtra, India have been identified by using remote sensing and GIS techniques. Various thematic maps such as Land use/Land cover, stream order, slope etc. are prepared using remote sensing application. In the present paper, Cartosat 1 data has been used to identify the groundwater potential zones by integrating various thematic maps generated on 1:50,000 scale. These maps are integrated after assigning weight factors to the identified features in each thematic map. Suitable zones for the construction of different water conservation measures inthe study area were identified. Suitability criteria are developed according to field situations for slope, soil, drainage network and rainfall. The final map showing different categories of suitability sites for water harvesting structures such as Check dams, percolation ponds, farm ponds, Contour bunding, and Contour trenching have been suggested.
