| Abstract | The role of groundwater is very important in the management of water resources with increasing demand. A comprehensive research for the safe yield of the groundwater is much needed as full use of the available surface water has already been reached in the Kathmandu Valley.
The natural recharge of the groundwater basin has been estimated by the Water Balance Model with the mean monthly computations for the period of 1976 to 1988. The safe yield has been predicted through the simulation of the groundwater flow starting from 1975 to year 2000 by a two-dimensional model which is calibrated to the initial condition.
The long-term average groundwater recharge has been estimated as 45690 m3/day which is 3 percent of the precipitation over the basin. The safe yield has been estimated based on total pumpage from the aquifer in Kathmandu Valley. The safe yield in long term basis has been estimated 45504 m3/d. The safe yield of the groundwater basin has also been estimated in conjunctive with the planned future surface water supply schemes. Various scenarios of water demands have also been considered. |
