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...

2. For the drainage system as shown in figure below, determine the design flow and determine the pipe size for each of the sewer section by rational method. The rainfall intensity (in/hr) is given by the IDF curve in second figure. The design frequency storm is 10-year storm. Flow from each area is shown by an arrow. The flow velocity in each pipe can be calculated by Manning's equation or Hazen-William equation by assuming a full...
