Evaluating Hydraulic Characteristics of the River/Aquifer System and Predicting Yield
Characterizing the hydraulic properties of the aquifer (transmissivity, storage coefficient and boundary conditions) and the river/aquifer interface (leakance) is essential in providing the information needed to evaluate the yield potential of riverbank filtration systems. Carefully designed and executed pumping tests can provide the data needed to quantify the hydraulic characteristics of the hydrogeologic regime. Once the relevant hydraulic parameters have been determined, they can support calculation of system yield estimates by careful application of analytical equations and/or groundwater flow models.
