Sand in the Grand Canyon: Two U.S. Geological Survey Studies
Information about how "a controlled flood was held during late March and early April of 1996 to help researchers determine if periodic large releases of water from Glen Canyon Dam can rebuild sandbars and restore other habitats [along the Grand Canyon of the Colorado River] that have deteriorated since the dam's completion in 1963." Includes discussion of the studies of sandbar formation and sand distribution. From the U.S. Geological Survey (USGS).
