Rainfall intensity on a plane is 3.5 cm/hr for a duration of 8 min. The plane of 60 m x 60 m has a slope of 0.005. Draw the complete hydrograph. n=0.03. Check whether the kinematic wave theory can be applied to Problem 9.15 for formulat- ing the hydrograph. Determine whether the kinematic wave theory is valid for Problem 9.16 to formulate the hydrograph. Use the Muskingum-Cunge method to route the following hydrograph: Time (hr) Flow (cfs) 12 24 36 48 60 72 84 96 300 450 750 825 740 600 400 270 The flood channel characteristics are: peak flow = 825 cfs, area of channel cross section= 120 ft, width = 30 ft, channel slope = 0.00015, reach length = 50 mi. ==
