The purpose of this Public Works Technical Bulletin (PWTB) is to transmit information and provide guidance for the selection and use of check dam structures for erosion control. The information is based on data collected from field and laboratory evaluations done by the Engineer Research and Development Center – Construction Engineering Research Laboratory (ERDC-CERL) and the University of Illinois. Since many land managers commonly use a variety of check dam systems in conjunction with other best management practices (BMP) for comprehensive erosion control programs, there is a need for independent evaluation. Current data on check dam system performance is lacking. This PWTB will help land managers select suitable check dam structures for certain conditions. This information will help reduce product failure due to misapplication and provide results based on side-by-side comparisons of commonly used check dam systems found on military lands.
