The United States contains nearly 3.5 million miles of rivers, creeks, and other such streams. Erosion is occurring on over half a million miles of bank lines along these streams. The resulting total annual damages of about $270 million are a serious economic loss to both private and public interests located along these streambanks. The U.S. Congress has recognized this problem and the potential benefits to be derived by controlling bank erosion. Legislation has been enacted to develop low-cost-effective bank protection guidelines for both public works and private citizens. A developmental program is being conducted by the U.S. Army Corps of Engineers for execution. An interim status report on the program is presented herein. (Author).
