Consider a watershed with a drainage area of 10 square miles and a mainstream length of 7.5 miles. The main channel extends from the watershed outlet to the point opposite the centre of gravity of the watershed over a distance of 3.5 miles. Given a time of concentration (Ct) of 1.5 hours and a dimensionless slope of the watershed (Cp) of 0.5, determine the standard synthetic unit hydrograph for this basin. What is the duration? Using Snyder’s method, calculate the 45-minute unit hydrograph parameter
