Abstract

This paper shows the possibility of tapping artesian water of an ignimbrite aquifer for generating addional power during low streamflow seasons. After the hydrogeological factors are considered which determine the feasibility of releasing artesian groundwater at optimal times to supplement hydro-electric generation, aquifer parameters are determined in a hydrogeological field study and used used to set up a steady state groundwater model of the catchment area. The calibrated model indicates low values for the aquifer recharge, which in addition to the rather small values of the estimated transmissivities
