A study was undertaken to evaluate the future performance of various flood control alternatives on the Arkansas river near La Junta, CO. The Major study component was the application of HEC-6 "Scour and Deposition of rivers and reservoirs" to simulate long-term (100 years) changes in the stream profile. A complicating factor was the existence of 11 major irrigation diversions and 4 tributaries in the 100 mile long study reach. This paper describes the development of representative data for the long-term analysis, operation of the model, calibration and simulation strategies employed, interpretation of model results, and computational aspects of this applications.
