Abstract
Seepage impedance caused by clogging which appears in surface water drainage and ground water recharge facilities reduces the operation efficiency. In the mathematical model of the clogging, the filter cake was introduced as the main mechanism. Obtaining the model parameters through a series of experiments, we carried out short term recharge simulations and compared the results with model experiment results. Conducting a shrinking factor and a cracking factor of the cake, we carried out long term recharge simulations and compared the results with the those of an actual recharge basin. These comparisons show good agreements.
