摘要
Dulapally watershed in granitic terrain covers about 34 sq. km lying north of Hyderabad City in semi-arid tropics. Groundwater recharge has been estimated considering the soil- plant and agroclimatological conditions from daily rainfall and pan evoporation data during 1974 to 1990. The average annual recharge over 16 years worked out to be 124 mm. The temporal variation of the recharge estimates have been validated through simulation of well hydrographs in a nested squares finite difference aquifer model by feeding them as temporal input during transient condition.
