This paper is intended to study the effect of using incline intermediate sheet pile and finding the effect of change for its angle, besides the upstream and downstream piles rest in homogeneous soil layer on the seepage, uplift pressure exit gradient at toe of hydraulic structure using computer program SEEP/W software. From the software test carried out many cases, in beginning, finding the best distance between the three sheet piles then finding the best depth of three sheet piles finally using the angle for incline intermediate sheet pile ( θ =30,45,60,90,120,135,150) degree in three cases for first and last sheet piles when the angle of them ( θ =30,60,90)degree. Also for each run the quantity of uplift pressure, exit gradient and discharge at toe of hydraulic structure were determined to develop an empirical equations. Depended on the software program tests were carried out with three different value of each following parameter: upstream sheet pile depth, downstream sheet pile depth, intermediate sheet pile depth, upstream sheet pile angle, downstream sheet pile angle and four different value of distance between the sheet piles, then it carried out with seven different value of intermediate sheet pile angle, all of them with using constant upstream head and permeability for soil layer.
