The grass swale will be made of Bermuda grass (n = 0.030) and the existing soils are clayey. The slope of the swale is 4%. The permanent swale is in a residential neighborhood (Table GS-1) with 2 acre lots with "C" soils in Tuscaloosa AL. The watershed area draining to the swale is 32 acres in area and the time of concentration is 1 hour. Determine the Q peak for the 100-year 24-hour storm. Your design must provide a minimum of 0.5 feet of freeboard when flowing at normal depth and must not exceed permissible velocity requirements (Table GS-3). In addition to design calculations you must provide a standard detail for each section (Figure GS-1)
