<span>The seepage through a permeable soil under hydraulic structure exerts uplift pressure and <span>may carry soil particles there by leads to piping. This paper concerns to study the effect of using <span>intermediate sheet pile under the apron of hydraulic structure besides the upstream and <span>downstream piles rest on non-homogeneous soil layer. This configuration aim to show how it affect <span>the uplift pressure, exit gradient and seepage discharge at toe of hydraulic structure by using <span>computer program SEEP/W Package. <span>From the software test carried out two cases, first case using two sheet pile one at the <span>upstream and the other at the downstream, then compare its results with the second case when the <span>sheet pile at upstream, downstream and intermediate pile introduced Also for each run the quantity <span>of uplift pressure, exit gradient and discharge at toe of hydraulic structure were determined to <span>develop an empirical equations. Also, the results have been verify with artificial neural network <span>(ANN), this verification shown good agreement between them.</span></span></span></span></span></span></span></span></span></span></span></span>
