I need help on this problem Manning equation problem for parts a, especially rearranging the equation. Thank YOU They constructed 20-feet-high levees along the river channel. The channel constrained by the levees is 250 feet wide. For this exercise, assume that the channel cross-section can be approximated by a rectangle, with width, w, and the water depth, d. The Hydraulic radius is 17.24ft. assume that the channel slope is 0.0003 (a)Since late 1970s there was a push to restore river ecology and let vegetation grow back in the channel. Assuming that vegetation in the channel will increase the Manning’s coefficient by 0.01, how much higher would the levees have to be to contain a flood with a maximum flow rate of 25,000 cubic feet per second?
