Abstract

The sustainable water availability in a semi-arid region is achieved by construction of permanent/temporary water storage systems and distributory networks. Their functional status is crucial for regional development. The objective of this study is to develop methods in evaluating the functional status of water storage supply infrastructures. In addition to the thematic map, orbital satellite (IRS) images and ground based information were used in assessing the storage capacity and physical conditions of Yerala River basin, part of Krishna River basin in India. Assessment of Water infrastructure condition (WIC) was carried out based on Reservoir Storage Efficiency (RSE) and canal conditions (CC) were developed. The storage and distribution systems are functioning at 38 to 68% of their capacity. Keywords: Yerala River, Krishna River, semi-arid region, water storage capacity, sustainability of water, water infrastructure condition (WIC) reservoir storage efficiency (RSE), canal conditions (CC), multi-criterion analysis, supply and demand analysis.
