A masonry dam of trapezoidal cross section, with one face vertical, has a thickness of 2 ft at the top and 10 ft at the bottom. It is 22 ft high and has a horizontal base. The inclined face is subjected to water pressure, the water standing to a depth of 15 ft above the base. The weight of the masonry is 150 1b per cu ft. If there is no hydrostatic uplift, where will the resultant pressure intersect the base? Is this a good design?

1.) Situation 11. A rectangular vertical gate, 0.60 m wide and 2.45 m high and weighing 1.78 kN, is hinged at the bottom. There is water on both sides of the gate, 4.9 m on one side and 1.80 m on the other. The gate, however, is held in place by a horizontal force F applied at the top of the gate. Under the above conditions, determine the horizontal force F and the amount and direction of the reaction at the hinge. Assume weight of water to be 9.81 kN/cu.m. W.S. 2.45 m 0.60 m B 1.78 kN 2.45 m 1.80 m P.- P: hinge

Tank is rigidly bolted to a foundation at grade. The weight of the tank when full is 444,820 N. It is located at seismic zone 4. Assume sufficient free board exists at this tank. The proximity of the tank to seismic source type B is estimated to be 10 km. Assume the fundamental period of tank is 0.05 sec. Based on NSCP 2015 Requirements, determine the lateral force on tank II.

The viscous of water which flow through the interconnected pore spaces insoil can be effectively used to obtain the safety against heave on thedownstream side of a hydraulic structure. Based on the statement, use thesketch to explain the force due no seepage, upward seepage and downwardseepage on a volume of soil.
A dam includes a sheet pile "cut off" wall near the toe, installed to 7 ft below the groundline. Water seepage is assumed to be at steady state at this time step shown. At this time, the depth of the upstream pond (headwater) is 5 feet. The groundwater is at the same level as the ground on the downstream/tailwater side. The sand stratum thickness, where water is flowing, is 9 ft thick. The permeability of the sand, in the zone of the flow net, is k=42ft/day, the length of the dam (into the page) is 150 ft, and the unit weight of the sand is γsat=128 lb/ft3 (saturated unit weight of the soil). Use γw=62.4 pcf (unit weight of water) for your calculations, where necessary.What is the factor of safety against a quick condition? (use the dimensions given in the problem state to help estimate lengths, where needed)
