Salt River Channelization Project: Model Study

Abstract

TWO models were tested in order to determine the adequacy of a channelization scheme for Salt River near Sky Harbor International Airport, Phoenix, Arizona. One fixed‐bed model was used to study velocity patterns, flow stages, bank freeboards and bank protection requirements. One distorted movable‐bed model was utilized to study erosion and deposition patterns and bank stability in the proposed scheme. Incipient motion of bed particles and tractive force theory for stability of banks were utilized for modeling the various complicated parts of the movable‐bed model. Results were compared with mathematical model results, and good agreement was observed. Recommendations for improving the channelization scheme were given.
