1. Referring to the detention basin shown in Figure 15-22, compute a chart of storage volume values for elevations 100, 101, 102, 102.5, 104, and 106.

2. Compute the outflow rating for the detention basin shown in Figure 15-22. Use the same elevations listed in problem 1. Ignore the constriction caused by the outflow pipe.
