dc.description.abstractThe aquifer formed by the fluvial deposit of the River Storelva at Sauda in Rogaland has been investigated by geophysical measurements, drilling, pumping and groundwater modelling techniques. This aquifer is being considered as a potential water supply source for Sauda municipality. The principal objectives of the study were i) to provide a more accurate assessment of the aquifer's capacity than that provided by previous studies ii) to determine the effect of municipal abstraction borehole owned by a mineral water company and iii) to assess the use of artificial recharge to reduce any such effect. The groundwater flow model MODFLOW and the particle-tracking MODPATH were used to model the aquifer. This modelling indicated that the capacity of the aquifer is approximately 20 l\/s. The modelling also indicated, however, that any significant municipal abstraction will alter the groundwater flow pattern in the aquifer and may lead to increased pumping costs for the mineral water company as a result of increased drawdowns in the aquifer. The modelling results also indicate that although artificial recharge may enable municipal abstraction to be increased without resulting in additional drawdown at the mineral water borehole, the integrity of the mineral water may be compromised.
