Flood as a restoration tool in the Grand Canyon

The U.S. Department of the Interior has periodically been releasing large volumes of water into the Grand Canyon in an attempt to mobilize sediment and rebuild beaches in a river system that has been sediment deprived since the installation of the Glen Canyon Dam in 1963. In November 2013, they planned for a high flow release (>34,000 cubic feet per second) into the Colorado River, which normally flows at 8-9,000 cfs. They maintained high flows for 4 days during a period that the Paria River was releasing large amounts of sediment into the Colorado River.  River managers hoped to entrain the high sediment load of the Paria using high flows in the Colorado River so that they would be carried downstream and deposited further down than they normally would be.  Flooding, flood routing, river restoration and Colorado River water resources are all subjects that I am very interested in being more involved with in my future research endeavors.
