Hydrograph for a watershed having a drainage area/ Civil Engineering
For the data given below, derive the 2-hr unit hydrograph for a watershed having a drainagearea of 216 km^2, assuming a constant baseflow of 20 m^3/s.
Calculate and plot the S-curve and unit hydrographs for 4-hr and 8-hr.
Calculate and plot the direct runoff and streamflow if the following excess precipitation was found: 2 cm at 2 hr; 3.0 at 4 hr; and 1.0 cm at 6 hr.
