Insufficient water supply is one of the most important factor governing agricultural productions. In addition to rainfall, a thorough knowledge of seasonal values of evaporation and crop transpiration, runoff, deep drainage and soil water storage is required to estimate the water need of crop. Water management is crucial to rightly offer and economize on water use in improvement of rice productivity. This paper aims to estimate Rice water requirement and irrigation water requirement in Dehradun district, based on the New Loc-Clim projected meteorological data. Rice water requirements are estimated by using crop coefficient approach. Reference evapotranspiration are calculated by FAO Penman-Monteith method. Moreover, the irrigation water requirements are simulated by calibrated CROPWAT-8.0 model using the meteorological parameters.
