One-dimensional water flow through the sandy soil is shown in the following setup; a 1) Calculate and draw the elevation head, pressure head, and total head; from point a to point e. 2) Calculate and draw the discharge velocity and seepage velocity; from point b to point e. Note that the void ratio (e) for sand I and sand II is 0.25 and 0.17, respectively. Assume the coefficient of permeability k in cm/sec for sand I and for sand II. 3) Calculate the quantity of seepage, if the area of the sand I and sand II is 0.42 m and 0.31 m, respectively.
