For a certain location, the following precipitation data is known: 2 year storm: 5 min duration = 0.324 in, 15 min duration = 0.637 in, 60 min duration = 1.08 in 100 year storm: 5 min duration = 0.625 in, 15 min duration = 1.22 in, 60 min duration = 2.47 in Use this given precipitation data, along with the approach contained in equations 7.2.1, 7.2.2, and Table 7.2.1, to calculate the precipitation depth for each storm in the table below. (Note: do not write on this paper-conduct your calculations separately.) Duration 2 yr 5 y Return Period 10 yr 25 yr 50 yr 100 yr 5 min 10 min 15 min 30 min 60 min Question 2 The 100 year, 24 hour storm in Richwood, WV is estimated to have a precipitation depth of 5.30 inches. Use the 24 hour SCS Rainfall Distribution (Table 7.2.2) to develop a plot of precipitation depth (y-axis) vs time (x-axis) for the 24 hour storm. Be sure to include axis titles, with units, in your figure. (Note: all of WV is in the "Type II" zone.)
