Case Western Reserve University project ties soil conservation and river management together
Date:10/1/2008

CLEVELAND Sediment in rivers comes from erosion of the landscape as well as the erosion and collapse of the banks themselves. Just how much each source contributes to a river and how it affects the flow and path of that river is the subject of research by Peter Whiting, professor of geological sciences at Case Western Reserve University.

Taking measure of certain radionuclides found in the soil, including beryllium and lead, at various points along a 423-km-long section of the Yellowstone River, Whiting has determined how much of the sediment in the Yellowstone came from runoff and how much came from the streambanks. For example, streambank erosion contributes approximately 50 percent of the sediment at measurement sites up-river, increasing to 89 percent at Billings, Mont. In river basins where significant portions of the surrounding landscape are used for agriculture or forestry, the percentage of sediment coming from streambank erosion drops below 50%.

Whiting will present his findings on Monday, October 6, at the 2008 Joint Meeting of the Geological Society of America, Soil Science Society of America, American Society of Agronomy, Crop Science Society of America, and Gulf Coast Association of Geological Societies in Houston..

Radionuclides occur in soil both from natural processes and as fallout from nuclear testing. Beryllium and lead are found in greater concentrations at the surface of the soil. All the beryllium will be found in the top two centimeters of the surface soil but lead will be found to greater depth.

Beryllium and lead have markedly different half-lives. Lead has a 20-year half life, while that of Beryllium is only 53 days. Comparing the activities of both elements in the river's suspended sediment to the surrounding landscape and streambanks helps provide a detailed profile of where the sediment originates.
