Straw Roll/Bale Barrier

Straw Roll/Bale Barrier POLLUTANTS ADDRESSED: Nutrients and Organics, Salinity, Sediments

DESCRIPTION: Straw barriers are semi-permeable barriers that temporarily contain sediments generated by flows across bare or disturbed ground.

LOAD REDUCTION MECHANISM: Nutrients/Organics Management- The barriers traps nutrients that are carried by overland water flows.

Salinity Reduction- They also temporarily impedes the flow of saline waters.

Sediment Reduction – They temporarily trap sediment from overland water flows.

MEDIUM

HIGH Straw bales are temporarily placed perpendicular to surface sheet flow. In small channels velocities are high enough to require anchoring of the bales with steel or wooden stakes. These barriers should be considered temporary and require maintenance.
