# Question: 232 the precipitation and streamflow for the storm of may...

###### Question details

2.3.2 The Precipitation and streamflow for the storm of May 12, 1980, on Shoal Creek at Northwest Park in Austin, Texas, are shown below. Calculate the time distribution of storage on the watershed assuming that the initial storage is 0. Compute the total depth of precipitation and the equivalent depth of streamflow which occurred during the 8-hour period. How much storage remained in the watershed at the end of the period? What percent of the precipitation appeared as streamflow during this period? What was the maximum storage? Plot the time distribution of incremental precipitation, streamflow, change in storage, and cumulative storage. The watershed area is 7.03mi2.
