Sediment Routing Model of the Middle Rio Grande
The approximately 65-km reach of the predominantly sand-bed Middle Rio Grande between the Angostura and Isleta Diversion Dams has been significantly modified by human activities, and the reach continues to respond to these and other factors. Construction of Cochiti Dam reduced the magnitude and frequency of flood peaks and the downstream sediment supply, causing 0.6 to 2.4 m of degradation in the reaches below the dam. Ongoing efforts to improve the efficiency of downstream water delivery and instream habitat will cause additional modifications to both the physical system and the quantity and timing of flows through the reach. To help understand the factors that control the behavior of the river and provide a tool to evaluate potential impacts of future changes, a one-dimensional (1-D) sediment routing model of the reach was developed and calibrated using the HEC-6T computer program.
