A two-step method of incorporating uncertainty and risk in stream restoration design has been developed. The Design Failure Modes and Effects Analysis (DFMEA) method and risk quantification is applied to a stream relocation project in Pennsylvania. Both sediment transport capacity and supply analysis and alluvial channel modeling design methods were shown to reduce uncertainty and risk by detecting design deficiencies that the initial design using incipient motion tests overlooked.
