Question J. (2010 ) A 2-hour unit hydrograph for a drainage area is given below. a) Derive the streamflow hydrograph for a storm that produces 0.5 in. and 1.0 in. of excess precipitation over two consecutive 2-hour periods. Assume the baseflow is negligible. b) What is the peak rate of the streamflow and time to peak? Present all steps of your calculations. UH Time (hr) (cfs) 0 12 26 12 8 0 14
The 4-hr unit hydrograph for a watershed is given as below. Time (hr) 2 4 6 8 10 12 14 Unit hydrograph (m3/s/10 mm) A design storm has 1.5 cm/hr in first 2 hr and 1.0 cm/hr in the second 2 hr. The abstraction rate is 0.5 cm/hr. Base flow is 10 m/s. Calculate the total runofi hydrograph.
