CASE STUDY- West Fork Beaver River, West Point, OH. Constructed Sept
CASE STUDY- West Fork Beaver River, West Point, OH. Constructed Sept Minimal height Bendway Weirs in a gravel-cobble-sand-silt bed stream

Functions of Bendway Weirs on the West Fork Beaver River:
Main function is realignment of the thalweg through the bend and also center the thalweg within the channel immediately downstream of the bend where a pipeline was exposed by erosion. The pipeline cover was protected with Articulated Concrete Mattress (ACM). Secondary function was to provide some bank stabilization within the bend.
