Wind fetch

A long fetch creates a high energy wave.

l erosion and flooding. It also plays a large part in longshore drift as well.

Fetch length, along with the wind speed (wind strength), determines the size (sea state) of waves produced. The wind direction is considered constant. The longer the fetch and the faster the wind speed, the more wind energy is imparted to the water surface and the larger the resulting sea state will be.
