On condition that the seepage coefficients of sediment and stratum are nar- rowly or widely different, seepage stratum is homogeneous or layer. The muddy water seepage integral and differential equations based on Darcy’s law are established, and then their difference formula of the differential equations are derived. The method pre- sented was used in the deep recharge test in Shizuishan, where power plant cooling tail- ing water was used to recharge and mine deep underground water. This is firstly used in China. The law of sediment accumulation on the earth surface, and the rule of infiltration capacity changing with time are studied. The pattern of water table changing with time affected by the recharge irrigation is predicted.
