Erosion Control and Water Harvesting
The RPMC uses a variety of low-tech methods to stabilize eroding streamlets and small gullies. These low-tech structures use readily available materials, such as rocks, logs, and slash materials, to both prevent further erosion and harvest water. The simple structures spread out surface flows, encourage the precipitation of suspended sediment, and increase the area that is wetted by runoff. Restoring wet soil conditions to areas that were previously dry due to quick surface runoff encourages vegetation, which in turn captures additional fine sediment particles.
