A rainfall hyetograph is provided for a 6-hour storm event, which occurred over a watershed with an area of 2100-acres (Ac). If the Phi-index is 0.71 in/hr, calculate the volume of runoff (VRO) from the storm (in Ac-ft). Report your answer to the nearest tenths (0.1) place. HINT...the answer should be around the 500-1,500 Ac-ft range (yes, it is a big range if you need to guess). Intensity (in/hr) 2.5 2.0 1.5 1.0 0.5 0.0 0 1 2 3 4 Time (hr) 5 6 7 2

The ordinates of a 6h-UH of a watershed having a drainage area of 393 km^2 are given below. For a storm over the watershed having excess rainfall of 5 cm for the first six hours and 15 cm for the second six hours, compute the direct runoff hydrograph ordinates and plot the hydrograph. Compute the depth of direct runoff in cm. Assuming constant baseflow of 100 m^3/s, compute the storm hydrograph ordinates and plot the hydrograph. (List all the DRH ordinates in order, separated by a single space.)
You are designing a drainage system for a residential site in Atlanta using a 10-year return period. The site has an area of 1 ha, a flow length of 100 m, an average slop of 1%, a Manning's number of 0.25 and Type B soil. Drainage regulations require that the kinematic wave equation be used to calculate the time of concentration. You are allowed to use either the rational method or TR-55 to calculate the peak runoff rate. It is suggested you used a runoff coefficient of 0.4, which is typical for residential sites. What curve number would be required for both the rational method and the TR-55 method to provide the same peak runoff rate?
