Most river bank protection structures are not designed to improve aquatic or riparian habitat and restoration projects often lack sufficient engineering and geomorphic analysis. Recognition of the ecological importance of instream wood debris (WD) has led to its extensive re-introduction in many parts of the United States, but limited understanding of the WD stability hampered these efforts. After appropriate analysis to determine the appropriate size, position, frequency, and type of WD, engineered log jams (ELJs) can restore riverine habitat and in some situations provide effective bank protection.
