This article needs more links to other articles to help integrate it into the encyclopedia. This is because the moving water lose proportionatley less energy in ovrcoming friction than when the ratio between cross-sectional area and the wetted perimeter is low.
There will be more water flowing over a wider; deeper channel, because it has greater surface area.
This is because less lateral erosion will occur, in-order to deepen the channel. Do you come here. Questionnaire to geography exam will be. Proudly powered by Weebly.

The wetted perimeter is the total length of the river bed and banks in cross section that are in contact with the water in the channel.
