Title: SEDIMENT CONTROL BASIN
Caption: A sediment control basin can mitigate the effects of increased erosion and sedimentation after a wildfire. (a) Cross section of a sediment control basin. Sediment carried by storm water settles out in the basin, while the water filters through loose gravel into a riser, where it then drains through a pipe to an outlet. Accumulated sediment is periodically removed mechanically. Black arrows indicate direction of water flow. (After Soil Conservation Service. 1974. Erosion and sediment control) (b) A sediment basin constructed to trap sediment that eroded after a wildfire in southern California. (Edward A. Keller)
