New research: Geomorphologists map fine sediment in Colorado River to improve sandbar management
Grain by grain, sandbars are ecologically important to the Colorado River system for humans and wildlife, say scientists. How sand, silt and clay move along and become deposited within the river corridor in the Grand Canyon National Park, downstream from Glen Canyon Dam, has become an important question to a number of government agencies as well as to Native American tribes. The answer impacts the entire Colorado River ecosystem and will help scientists better understand how the Colorado River system works.
