Andhra Pradesh like many other states of India is a riverine state with two major rivers – the Godavari and the Krishna – and, three medium size rivers – Penner, Nagavali, Vamsadhara – along with many other minor streams, flowing through it, and it is the ‘rice bowl’ of India. With average annual rainfall at 940mm, Andhra Pradesh yields good amount of surface waters. The Central Water Commission has worked out the potential of surface water (78.9 km3) of Andhra Pradesh, and in the present study an attempt has been made to map various surfaces – lithology, geomorphology, land use and soils – on which runoff coefficients depend and to calculate the surface water potential rainfall zone-wise. Run-off coefficients of various units under the listed themes are averaged through overlay analysis in ArcGIS and the surface water potentialis calculated and the potential stands at 100.24 km3. Implications of lithology, geomorphology, soils and land use on various aspects to rejuvenate river systems are also discussed in detail.
