- Problem-1 A watershed is divided into sections as shown below. Runoff from each section will contribute to flow at gauge G as indicated in the table. For an excess rainfall intensity of 0.5 in/hr falling uniformly for 5 hrs, determine the resulting direct runoff hydrograph (DRO). D A C D Area [ac] 150 250 350 200 Time to G [hr] 2 4 GAfter a 2-hour storm, a station downstream from a 40 square mile drainage basin measures 9300 cfs as a peak discharge and 3400 acre-feet as total runoff. Find the 2-hour unit hydrograph peak discharge.What is the peak flow from a watershed with 5 acres and runoff coefficient of 0.7, for a 10-year return storm over 2 hours period using the Rational Method? (Use the IDF for Washington, DC)

Your team developed the unit hydrograph below for a 1 hour storm duration. Calculate the watershed response to the hyetograph provided and provide the total peak flow (cfs). Table 1.

- 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).

If the total runoff at the outlet from the catchment was 15 cm, the value of the -index (in mm/hour) is (a) 0.0 (b) 1.04 (c) 1.53 (d) Sufficient information not availableRunoff data have been collected for a 4-hour storm over a 120 acre watershed as indicated in the table. If the total volume of water infiltrated during the storm was 3.0 Ac-ft and the Phi Index is 0.1 in/hr, sketch the rainfall hyetograph with EVERYTHING labeled appropriately. Also, report the depth and volume of precipitation (in inches and Ac-ft, respectively) for each 1-hour period.
