International Journal of Water (IJW), Vol. 5, No. 3, 2010

Abstract: Spatial assessment of groundwater demand has been carried out as a part of sustainable water resources management in Northwest Bangladesh. ASTER images are synthesised for extracting the extent of irrigated land. The Penman–Monteith method is used for the calculation of reference evapotranspiration from climate data. Soil information is used for the estimation of water requirement for land preparation and seepage loss. The domestic water demand is calculated from population census data. The study shows that the irrigation water demand in the study area varies between 839 mm and 1212 mm, which amounts to about 96.5% of total groundwater demand.
