Abstract/Description: | Anantapur district has drought history date back to thirteen century and it is poorly developed district of Andhra Pradesh. In the present study an attempt has been to study physical characteristics viz., slope, drainage, geology, geomorphology, soils and water balance characteristics of Anantapur district, Andhra Pradesh using remote sensed data (IRS-IA LISS-I and Landsat TM), collateral data and selected field checks. Macro-watersheds have been delineated and sediment yield index (SYI) has been worked out using Flaxman model. The study indicates that out of fifty macro-watersheds delineated, thirteen are having SYI above 1300 and are prone to very high erosional hazard. Fourteen macro-watersheds are under high erosion prone condition. Only three macro-watersheds are very low erosion prone condition. Twenty seven macro-watersheds, which covers nearly 56 per cent of the total area of the district are under very high erosion prone condition needs immediate soil and water conservation measures to restore geo-ecological balance and obtain maximum productivity from land and water resources of the drought-prone Anantapur district. |
