A uniform layer of sand 10 m deep overlays bedrock. The water table is located 2 m below the
surface of the sand which is found to have a voids ratio e = 0.7. Assuming that the soil particles have
a specific gravity Gs = 2.7 calculate the effective stress at a depth of 5 m below the surface.
Answer
(solved), A channel is 2m wide at bottom; the length of each sloping side is 1.95 m; the width at water surface is 5.5 m the flow depth 1.2 m; and bed slope 1 in 5280. What is the discharge per minute? The values of Chezy’s C for this channel for different values of hydraulic radius R are as tabulated below.
Problem 1 solved, effective stress in soil, Calc
(solved), A channel carries a discharge of 5 cumec with a flow depth 1 m. The side slopes are 1 to 1 and bed slope 1 in 3520. Find the bed width and the velocity. The values of Chezy’s C for this channel for different values of hydraulic radius R are as tabulated below
