Sediment delivery in a changing climate

Documents and Media Posted on: January 23, 2015
The delivery and transport of sediment through mountain rivers affects aquatic habitat and water resource infrastructure. While climate change is widely expected to produce significant changes in hydrology and stream temperature, the effects of climate change on sediment yield have received less attention.Document Type: Briefing Papers

Enhanced sediment delivery in a changing climate in semi-arid mountain basins: Implications for water resource management and aquatic habitat in the northern Rocky Mountains

Publications Posted on: March 08, 2012
The delivery and transport of sediment through mountain rivers affects aquatic habitat and water resource infrastructure. While climate change is widely expected to produce significant changes in hydrology and stream temperature, the effects of climate change on sediment yield have received less attention.

An annotated bibliography of the hydrology and fishery studies of the South Fork Salmon River

Publications Posted on: October 22, 2008
A brief summary of the land management history of the South Fork Salmon River (Idaho) watershed includes citations and annotations of published and unpublished reports of fishery and hydrology studies conducted in the South Fork drainage for 1960 to 1986.

Mountain erosion over 10 yr, 10 k.y., and 10 m.y. time scales

Publications Posted on: July 24, 2006
We used cosmogenic 10Be to measure erosion rates over 10 k.y. time scales at 32 Idaho mountain catchments, ranging from small experimental watersheds (0.2 km2) to large river basins (35 000 km2). These long-term sediment yields are, on average, 17 times higher than stream sediment fluxes measured over 10–84 yr, but are consistent with 10 m.y. erosion rates measured by apatite fission tracks.
