Estimation of Reference Evapotranspiration using Cropwat For Kadam Watershed

Abstract

Due to the overuse of available water resources, it has become very important to define appropriate strategies for planning and management of watershed. The objective for the study is determination of reference evapotranspiration using CROPWAT 8.0 software in GIS environment, which includes a simple water balance model and one of the main component part of the hydrologic cycle, which allows the simulation of crop water stress conditions and estimation of yield reductions based on well-established methodologies. This paper focused on the estimation of reference evapotranspiration using Cowpat 8.0 .
