For an embankment dam, the longest fetch is equal to 10 km, and is normal to dam axis. Assume that the upstream slope of the dam is 3H:1V, and the average reservoir depth D is 25 m. No upstream berm exists. Calculate the minimum freeboard of the dam. (The upstream slope is protected using ripraps, and the design wind velocity is 80 km/hr).
