Study of Gandorinala Catchment Area by using Geographic Information System (GIS) and Remote Sensing (RS)

The catchment area requires a host of inter-related information to be generated and studied in relation to each other. GIS (geographical information system) and RS (Remote sensing) is used in this study. ArcGIS 10.1 and ERDAS 8.7 has been applied to analyze terrain characters, to determine potential of water capacity and computing the geographical references data, which add new dimensions to environmental management for a part of Gandorinala catchment area in Gulbarga district, Karnataka and is located between longitude 17°35'51�North and 76°54'52"East. The Gandorinala is a medium irrigation project located near Belkota village in Gulbarga district in Karnataka State across river Gandorinala, a tributary to river Bennithora which in turn joins Bhima river of Krishna Basin. The study area covers 371 sq.km in Karnataka region. The thematic maps of catchment area have been generated. The check dams and percolation tanks are proposed at catchment area.
