A 200-acre catchment area contains 50 acres paved surfaces (C = 0.8), 100 acres buildings (C = 0.7), 40 acres open lawn space (C = 0.15). Determine the peak discharge Qp (cfs) by the Rational Method if the duration of the storm is 50 minutes. Assume 100-year return period storm. Use formulas/graphs from Houston City Manual.

In a given year, a catchment with an area of 200 km2 received 1300 mm of rainfall. The average evaporative energy flux due to evapotranspiration was 45 Watts/m2. Assuming negligible change in soil and groundwater storage, and also negligible interception. Estimate the average rate for that year, for the river draining the catchment (in both mm/year and m3/s).

Suppose that we have a reservoir that has a surface area of 50 acres, with an average depth when full of 15 meters. [Conversion: 1 acre = 4096.86 square meters] If the reservoir were to start out with a depth of 0 meters and eventually be filled to a depth of 15 meters, (1) how much volume of water will have been added in the filling of the reservoir from 0 meters depth to 15 meters depth? (2) What mass...
