Abstract
Spokane Valley-Rathdrum Prairie (SVRP) aquifer is the sole source of drinking water to more than 500,000 residents in Spokane County, Washington, and Bonner and Kootenai Counties, Idaho. A model was developed, by employing MODFLOW 2000, to simulate the flow in the SVRP aquifer so that it can be used by regulators and policy makers in decision making with regard to management of this resource. Among the inflows to the aquifer, the recharge and tributary basin flow estimates can be considered to be most uncertain. The objective of this work has been to evaluate the effect of uncertainty in recharge and tributary basin flow estimates on parameter estimation. The evaluation was accomplished by calibrating the model with variable recharge and tributary basin flow estimates. It was found that the primary parameter of concern, hydraulic conductivity of layer 1, increased, in general, with increasing recharge and tributary basin flows. A quantitative expression was developed to relate these variations to the hydraulic conductivity which allows estimation of the parameter for any variation in inflows between -10% and 10%.
