This typical <br /> section will be used for the entire channel reach. This will insure that the velocity <br /> will be below the limiting velocity of 5.0 fps, since the peak flow was determined at the <br /> downstream end of the reclaimed drainage channel. The minimum depth of the drainage <br /> channel will be at least 1.5 feet to insure over 1.0 feet of freeboard (dn = 0.28 ft). <br /> The reclaimed drainage channel will be topsoiled and revegetated according to Tabs 21 and <br /> 22, respectively. <br />
