Question 2 (30 points): The hydrologic flow path of the watershed is about 2,000 feet in length with a total elevation change of about 20 feet. This flow path may be divided into the following three segments as described below. The site has overland flow, shallow channel flow, and main channel flow The 2 year 24-hour rain event is 3.5 inches. The main channel is rectangular.Compute the water shed's total time of concentration.

A: Determine the overland flow travel time : Determine the shallow channel travel time. Part C: Determine the Main Channel travel time. Assume the channel is rectangular and with a width of 15 feet and a depth of 2 feet. Part D: Determine the time of concentration.
