Science As It Happens - Matched Photographs
Matched photographs of sandbars taken before and after the 2008 high-flow experiment are shown below. All of the sites here are below the confluence of the Paria and Colorado Rivers. The Paria River is a tributary to the Colorado River and is one of the primary sources of new sediment in the postdam era.
