Calculate peak runoff using the NRCS Method for the watershed shown in Figure 11-16 for a 100-year storm. The watershed is located in San Diego, California. For an average stream cross section, use that in problem 4. Assume that the entire watershed is wooded, hydrologic soil group B. Two-year rainfall, P₂, is 1.8 inches.
