With reference to Case Study $14\mathrm{.}2,$ consider flood routing based on the reservoir curve in Fig. CS$-14\mathrm{.}2$a$.$ If the runoff coefficient is $C=0\mathrm{.}8,$ what is the rainfall depth on a $24\mathrm{.}5-k{m}^2$ watershed that can be contained in a reservoir with a capacity of $1\mathrm{.}23{10}^6{m}^3?$

With reference to Case Study $14\mathrm{.}2,$ consider flood routing based on the culvert performance curve in Fig. CS$-14\mathrm{.}2$a$.$ If the runoff coefficient is $C=0\mathrm{.}64,$ what is the rainfall intensity on this $25-k{m}^2$ watershed that corresponds to the maximum culvert capacity of $4\mathrm{.}25\frac{m^3}{s}?$
