Online published on 8 April, 2020. Abstract This study employed field measurements and established techniques to estimate various water budget components in Ur river basin. The spatial information pertaining to the topography, land use and soil type were extracted using the Arc 9.3 GIS software which helped to quantify many of the water balance components. The water budgeting of the Ur river basin was done on a seasonal time scale for two seasons namely i.e. monsoon season (June to October) and non-monsoon season (November-May). The result showed the accuracy of un-accounted water during the estimation of the water budget components, and seemed to be satisfactory as it was limited to 6.94% of the seasonal rainfall, considering the complexities in estimation of all the major water balance components. The water budgeting study indicates that about 69.85 MCM of water flows down the stream (storage in tanks included in this value) in monsoon season. This study will help to gain a better understanding of the hydrologic processes occurring in the river basin for contingent planning of available water resources to different sectors.
