The net precipitation (runoff) in a three-hour period was 0.6 inches. The direct runoff hydrograph that resulted from this precipitation was in the form of a triangle with a time base of 21 hours and with a peak flow of 200 cfs that occurred 9 hours from the beginning of the runoff. (a) Sketch the direct runoff hydrograph. Be sure to label axes. (b) Determine the runoff volume (ft3) (c) Determine the drainage area (acres) (d) Sketch the unit hydrograph...

Using the soil-cover-complex (SCS) method, determine the total volume of runoff, in acre-ft, to be expected from a 50-yr, 24-hr rainfall event occurring at the southwest corner of Wyoming. Surveys indicate the soil is a clay loam, the land has been used as rangeland, recent conditions have been wet, and the land has been heavily grazed for a long time. The drainage area is 200 mi^2.

Consider a drainage basin having 60 percent soil group B and 40 percent soil group C. Five years ago, the watershed land use pattern was ½ wooded area with good cover and ½ pasture with good condition. Now, the land use has been changes to 1/2 pasture land, and 1/2 residential area (1/4-acre lot). Estimate the volume (In inches) of increased runoff due to the land use change over the past 5-year period for a storm with 6 in of...

Rain fell over a 1490-acre watershed at a constant rate of 2.75 inches/hour from 9 to 11 AM. Stream flow data recorded each hour are reported below. Note that the stream flow declines in dry periods to a relatively constant lower limit of 100 cfs (ft3/s). (a) Separate the base flow from the hydrograph. (b) When did direct (i.e., storm) runoff begin and end? (c) Find Pe,, the depth of excess precipitation, in inches. (d) Derive the 2-hour unit hydrograph....

Part I. Indicate whether true or false (T or F). ____ Storm water detention ponds typically are designed to regulate the outflow peak rate at or below a single target value, such as the pre-development (pre-land use change) peak runoff rate for a specified return period event. Detention storage alters the peak but not the volume of the outflow hydrograph. _____ Typical rating curves for weirs are concave upward. Typical rating curves for orifices are concave downward. ____ A sediment...

Consider a catchment that has a total area of 2.1 acres. Runoff from the entire catchment flows into one pipe inlet. Part of the catchment is a softball field (1.5 ac) and the other part is a set of paved tennis courts (0.6 ac). The softball field has a C value of 0.3 and a time of concentration of 7 minutes, and the paved area has a C value of 0.95 and a time of concentration of 2 minutes. The...

A piston pump having a barrel of effective volume 100 cm^3 is used to exhaust a vessel of volume 2.5x10^3 cm. If the initial pressure of the air in the vessel is 1 atm, estimate the reduction in pressure produced by two strokes of the pump, assuming that all processes are reversible and isothermal and that air behaves as an ideal gas. Further, estimate the number of strokes needed to reduce the pressure in the vessel from 1 atm to...

1. A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.4137 g sample of bianthracene (C28H18) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.361×103 g of water. During the combustion the temperature increases from 24.82 to 27.25 °C. The heat capacity of water is 4.184 J g-1°C-1. The heat capacity of the calorimeter...
