The project final report is available as NCHRP Web-Only Document 177.
The objectives of this research were to (1) critically evaluate the results of research completed since 1990 on fluvial geomorphic processes and predictions related to channel stability in comparison with current practice and (2) develop recommendations for adoption of specific research results by AASHTO and their use by the engineering community in general. This research addressed stability in cohesive soils, cohesionless soils, and rock; NCHRP’s primary interests in this project were long-term degradation and aggradation, and lateral migration.
