Considering Problems 14 and 15, determine the return period for the dike system that maximizes annual expected

Question:

Considering Problems 14 and 15, determine the return period for the dike system that maximizes annual expected benefit.

Data from problem 14 The frequency–discharge–storage–damage data for existing conditions at a particular area along a river is given in Table 13. 17. The storage–discharge data make up the rating curve, the discharge–frequency data compose the frequency curve, and the storage–damage data make up the storage–damage curve. Plot these three relationships.
