1.Determine the runoff hydrograph that would be generated by a design 3-hr storm that generates excess rainfall at a constant rate of 10 mm/hr. assume baseflow is constant at 1.0 m3/s. (Watershed Area is 17.64 km2
2.A footing under a brick pier has dimensions 300mmx300mmx300mm deep. what is the pressure applied to the soil under the above load. How does this compare with an allowable bearing capacity of 100kPa. Does this allow for a reasonable factor of safety.
3.A simply supported beam (one end has a pin support and the other a roller support) is 10 ft long. The width of the beam is 3.5 in. The beam supports three concentrated loads (2.5 kips 2 ft from A to B, 1 kip 5 ft from A to B, and 2.5 kips 8 ft from A to B). The allowable bending stress in the wood is 1800 psi and the allowable shear stress is 120 psi. Determine the minimum required depth of the beam.
