A catchment with a cement rubble surface has an average slope of 1%. The distance from the catchment boundary to the outlet is 500 ft. For a 60-min storm with an intensity of 1.5 in/hr, estimate the time of concentration using the kinetic wave and Kirpich equations.
Homework Answers
Solution:
Given:
average slope (s)= 1%
overland flow length (L) = 500 ft
intensity of Storm (i)= 1.5 in/hr
For cement rubble surface, Manning's roughness coefficient (N) = 0.024
Find: Time of Concentration (tc )
1) Using Kinematic Wave Equation
2) Using Kirpich equation

Time of concentration Determine the time of concentration (te) for an overland flow length of 200 ft on an area in Colorado Springs, CO, with a Manning's roughness coefficient of 0.10, for a design frequency of 25 years. The rainfall intensity-duration relationship for a 25-year frequency is as given in Table 1. Take the average slope of the area as 0.005 ft/ft. Recall that the time of concentration for inlets is given by: where time of concentration (in seconds) 1-overland...

A shallow reservoir has a one-square-kilometer water surface and an average water depth of 4 meters. Initially it is filled with fresh water, but at time t 0 water contaminated with a liquid pollutant begins flowing into the reservoir at the rate of 500 thousand cubic meters per month. The well-mixed water in the 60 80- reservoir flows out at the same rate. Your first task is to find the amount x(t) of 40- pollutant (in millions of liters) in...
