Write an essay consisting of at least 500 words addressing ALL of the following topics (a. through g.): Explain the rational formula, Q=CiA. If the rainfall intensity is 4.0 inch/hour, watershed area is 10 acres, and rational runoff coefficient is 0.7, determine the peak runoff rate in ft3/s. Use the rational formula. Describe the differences in computing peak rate of runoff using the rational formula versus the SCS TR 55 graphical method. Which method is simpler? What are the differences between the following storm water inlets: curb inlet, gutter inlet, and combined inlet? Why does land development typically increase the peak runoff rate? What are some methods used to mitigate the increased runoff rate? Describe at least three methods of stormwater quality control? Explain the differences between a main channel, floodway, and floodplain. What activities can occur in each?
