Trenchfill


The Corps uses trenchfill revetments to stabilize the existing channel and prevent the channel from changing course and developing a new chute channel that is less navigable. Trenchfill revetments are used when the channel is poorly aligned, and the standard articulated concrete mattress revetments can not be used.

Trenchfill revetments achieve the desired channel alignment by using the river as a dredge to remove the silt and sand in front of the trench. Once the the sand and silt has eroded away, the stone launches into the river and paves a new riverbank.
