Abstract: The River Errakalava, one of the major hydrological systems experiences perennial flooding in the lower part of Lower Errakalava watershed, damaging vast extents of Kharif crop and submerging several villages in the area of W.G. district, Andhra Pradesh during monsoon season. The flooding menace has continued despite the regulation of heavy flows in the river and its tributary systems by construction of Water Harvesting Structures. Watershed is a natural geographical area in which all running water drains to a single common outlet and making it as striking unit for methodological efforts to supervise land and water resources development and conservation. Moreover, man-made interventions to the flow patterns, the flooding is mainly attributed to the physiographical set-up, geological and geomorphological processes, and various other terrain elements that have direct bearing on the geometry of the watershed particularly in the lower part. A geo-scientific attempt which includes geo-spatial technologies has been made in the present study to assess various natural resource parameters in the Lower Errakalava watershed and ascertain the scientific reasoning of flooding. The study also provided suitable and lasting solutions to avert the perennial flooding in this area and the work conducted by watershed projects on protecting and developing non-arable lands, recharging ground water, improving the management of agricultural land and raising agricultural production.
Keywords: Watershed, Flooding Menace, Water Harvesting Structures.
