How is wave size related to fetch length

WebIn protected water the fetch length where the wind can blow will limit the ability of the wind to create waves. The fetch length can be read from a chart and is the length of the free water surface. If the fetch where the wind is blowing is narrow, as in a fjord, the wind effect will be less because of the friction against land on both sides ... http://www.geography-site.co.uk/pages/physical/coastal/fetch.html
