Description :
The Rio Grande downstream from Cochiti Dam exhibits spatial and temporal variability in lateral movement rates documented since 1918. A tremendous database exists that documents planform, bed material size, channel geometry, and water and sediment regimes. A statistical analysis reveals that migration rates primarily decreased with decreasing flow energy. The addition of a second parameter describing total channel width increased the explained variance to >60%. The findings show that lateral movement increases with increasing flow energy and with degree of braiding.
