Channel Treatments

Dams made of rocks, logs, straw bales or straw wattles are placed in small drainages to collect sediments and slow the velocity of water traveling down slope.

Uses of Channel Treatments

Channel treatments are used to modify sediment and water movement in stream channels, preventing flooding and debris torrents that threaten downstream communities and resources. These treatments often serve to slow water flow, allowing sediment to settle out, and then release sediments gradually through decay.

Dams made of rocks, logs, straw bales or straw wattles are placed in small drainages to collect sediments and slow the velocity of water traveling down slope. Straw bales are the cheapest and easiest options, but can be short-lived.
