3. A sand layer with a thickness of 1.5 m has been determine to exist for a 450 m length of a levee .The coefficient of conductivity or permeability of the sand layer is 3m per day. At the left side of the levee is a river whose water surface elevation is 160 m and at the right side of the levee is a ditch whose water surface elevation is 150 m .The length of the sand layer is 120 m,determine the hydraulic gradient of the sand layer A. 0.0789 B. 0.0833 C. 0.0678 D. 0.0587
