For a watershed comprising of 5000+Your Class No, hectares in area, the rainfall and runoff data are summarized below in the table. The maximum runoff rate was recorded as 4.82 m/s at hour 9 on the second day. Compute: a) 6-hr unit hydrograph, b) 12-hr unit hydrograph, c) A runoff hydrograph for the complex rain sequence as: 6-hr rainfall with rainfall intensity of 2mm/hr, followed by 6-hr rainfall with rainfall intensity of 7mmhr, and the last 6-hr rainfall with rainfall intensity of 11 mm/hr, and d) Determine the maximum runoff rate for the complex rain storm described in part c.
