WebFetch- and Depth-Limited Waves This Javascript app implements Eqns. 3-39 and 3-40 from the Shore Protection Manual. Input is the wind speed u10 measured 10 m above the sea surface, the fetch f, and the water depth h. The calculations adjust wind speed to adjusted wind speed Ua according to Eqn. 3-28a before being used. WebWaves are formed by the interaction of the wind over the water surface; they can develop as well in deep ocean, right at the coast of marine and lake basins, within estuaries, or even in very small ponds. Depending on the wind velocity, main direction, and fetch, waves attain specific heights (H) and periods ( T).

Webfetch, area of ocean or lake surface over which the wind blows in an essentially constant direction, thus generating waves. The term also is used as a synonym for fetch length, which is the horizontal distance over which wave-generating winds blow. In an … WebIf the field of the wave generating wind travels in the same direction, the amount of wave energy per unit of time moving into the wind-free area will be smaller than that produced … WebThe fetch: The distance that wind can travel (uninterrupted) over the water The strength of the wind The amount of time that the wind has been blowing over the water Now, we know from our definition of waves that waves are formed because of wind blowing over the water so these 3 factors may not come as a surprise. rotary antony
