A 250-k column load is to be supported on a 9 ft square footing embedded 2 ft below the ground surface. The underlying soil is a silty sand with an average N60 of 32 and a unit weight of 129 lb/ft3. The groundwater table is at a depth of 35 ft. Estimate the undrained settlement of the footing using the generalized elastic method with Christian and Carrier’s (1978) influence factors.

- 6. A lake with no outlet is fed by a river with a constant flow of 1200 ft3/s. Water evaporates from the surface at a constant rate of 13 ft3/s per square mile of surface area. The surface area varies with the depth h (in feet) as A (square miles) = 4.5 + 5.5h. What is the equilibrium depth of the lake? Below what river discharge (volume flow rate) will the lake dry up?arrow_forwardProblem 5 (A, B, C and D are fixed).

A sketch displaying length of stream and elevation Q.F1.3. Catchment's IFD obtained from the Buro of Metheorology for specified ARI Q.F1.4.Calculation of the time of concentration-this must include a detailed determination of the equivalent slope. Q.F1.5.Use must be made of the Bransby-Williams method for the determination of the equivalent slope.
