The Middle Rio Grande located in Central New Mexico is one of the most historically documented rivers in the United States. Since the early 20th century regulatory agencies have been interested and concerned with its management. A Hydraulic Modeling Analysis (HMA) of the Corrales reach, located 34 miles downstream of Cochiti Dam, was conducted. An extensive collection of data was used to determine the temporal and spatial changes in the channel. General trends for the Corrales Reach include a decrease in width, width to depth ratio, energy grade line slope and wetted perimeter, and an increase in mean velocity and depth during the 1962-2001 time period. The reach degraded as much as 3 feet in some areas during this same time period while the sinuosity remained the same. Since 1918 the width of the reach decreased from 1275 feet to 474 ft in 2001. Bed material coarsened from Cochiti Dam to just upstream of Albuquerque and the bed is expected to armor in the near future due to the lack of incoming sediment.
