Weir: Function, Common types & Issues

A weir /wɪər/, or low-head dam is a barrier across the width of a body of water that alters the flow characteristics of water and usually results in a change in the height of the water level. Weirs are used to control the flow of water in rivers, outlets of lakes, ponds, and reservoirs, industrial discharge, and drainage control structures. There are…
