TRB's National Cooperative Highway Research Program (NCHRP) Research Report 853: Guidance for Design Hydrology for Stream Restoration and Channel Stability provides written guidance and interactive tools to help hydraulic engineers assess the current conditions adjacent to a stream crossing and in the upstream watershed. Specifically, the guidance and tools provide support in assessing the current conditions adjacent to a stream crossing and in the upstream watershed to determine design effort, performing the appropriate hydrological and geomorphic analysis using a set of analytical and analog tools, and designing the channel through the stream crossing for stability and sediment balance.
In addition to the report, users can download the contractor’s final report; the spreadsheet-based Capacity Supply Ratio Stable Channel Design Tool (CSR Tool) for computing analytical channel designs that account for the full spectrum of sediment transporting events; an example of the CSR Tool being used on a sand bed stream (Big Raccoon); and an example of the CSR Tool being used on a gravel/cobble bed stream (Red River).
