Abstract

Water is essential element for human beings as well as echo system development. Population is increasing at rapid rate in developing countries, and climate change, Requirements of water resources is ever increasing. Due to this loss of life and water stress like drought, floods and climate changes in catchment areas, Because of this progress of the country economy and growth rate is reduces in and around the world. To overcome the above effects, water resources planning and management places a major role. For water resources allocation such as domestic supply, agriculture activity, industries, and power supply generations. Remote sensing techniques provided valuable information to water resources Engineer, Hydrologists and decision makers. ArcGis and HEC-HMS software tools plays a major role in data collection and analysis of data, calibration and validation of models ,simulation of models gives useful solution to water resources engineers. The present paper provides useful information of previous studies in Hec-Hms and ArcGis model studies of rainfall -runoff and surface water availability in catchments.
