Use Figure 22.2 along with Figure 22.1 to determine the gage height of these flood frequencies. (Use the flood frequency curve in Figure 22.2 to obtain the discharge, and then use that discharge on the rating curve to determine the associated gage height.)







20-year flood: ________________

300-year flood: ________________

400-year flood: ________________


20-year flood: 14 m
300-year flood: 16.6 m
400-year flood:16.7 m
