Abstract
An erosion and sedimentation study was conducted and the University of Illinois at Urbana-Champaign to evaluate the suitability of using check dams as an erosion control practice on military bases. Military readiness and effectiveness is enhanced by constant training and use of their lands; this training leaves the landscape disturbed and more susceptible to erosion. Check dams are an ideal management practice to study because of their small size versus their relative impact. Five types of check dams were investigated: compost filter berm, compost sock, foam and geotextile berm, plastic dam with a compost blanket, and a riprap berm. The check dams were evaluated in two studies, one on the University of Illinois South Farms and one under a rainfall simulator. Many climactic and soil factors were measured, although the main focus was on runoff and sediment removal. The investigation revealed that all structures effectively reduced the amount of sediment lost; all except the compost sock reduced it by over 50%. Some variability was observed and all products were statistically similar with high confidence. Compost berms were the least expensive form of check dam and would likely be the best all around option for the military to use.
