IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Identification of rainwater harvesting structure for yerala river using remote sensing and gis
Author : ABHIJIT M. ZENDE1, KAMALKISHOR R. ATAL2
Abstract
Remote sensing (RS) and Geographical Information System (GIS) were employed to identify rainwater harvesting
structures like percolation tanks, gully plugs, KT weirs, MI Tank and check dams in the Yerala River of Satara and Sangli
districts, Maharashtra, India. The thematic layers used were landuse/landcover, slope, soil, drainage and runoff from
derived from Landsat and collateral data. The runoff derived from SCS-CN using Arc-CN runoff extension of ArcGIS 9.3.
The aforesaid method portrayed as a function of runoff potential, which was categorized into three classes, viz., high (>
425 mm), moderate (200 425 mm) and low (< 200 mm). Parameters such hydrogeomorphology, geology for rock
porosity were considered as per Integrated Mission for Sustainable Development (IMSD) specifications for rainwater
harvesting structures. Applying the decision rules prepared from IMSD in GIS, potential rainwater harvesting sites
identified. Derived sites were investigated for suitability and implementation. The study yielded good result as could be
seen from the analysis.
