Wind fetch
Inoceanographywind fetch,also known asfetch lengthor simplyfetch,is the length of water over which a givenwindhas blown without obstruction.[2][3]Fetch is used ingeographyandmeteorologyand its effects are usually associated withsea stateand when it reaches shore it is the main factor that createsstorm surgewhich leads to coastalerosionandflooding.[citation needed]It also plays a large part inlongshore drift.[citation needed][clarification needed]
Fetch length, along with thewind speed(wind strength), and duration, determines the size (sea state) ofwavesproduced. If thewind directionis constant, the longer the fetch and the greater the wind speed, the more wind energy is transferred to the water surface and the larger the resulting sea state will be.[4]Sea state will increase over time until local energy dissipation balances energy transfer to the water from the wind and a fully developed sea results.[citation needed]
