Fetch
Water
The straight line distance across a body of water subject to wind forces. The distance which wind passes over water. The fetch is one of the factors used in calculating wave heights in a reservoir. The area in which waves are generated by a wind having a fairly constant direction and speed.
An area of the sea surface over which a wind with constant direction and velocity is blowing.

1. The area in which ocean waves are generated by the wind. Also refers to the length of the fetch area, measured in the direction of the wind.
2. In hydrologic terms,
- The effective distance which waves have traversed in open water, from their point of origin to the point where they break.
- 2. The distance of the water or the homogenous type surface over which the wind blows without appreciable change in direction.
