Impacts of Dam Removal on the Macrobenthos of the Elwha River Delta
For almost a century, the Elwha River has been constrained by the Elwha and Glines Canyon dams, which have severely restricted the transport of fine sediment downriver. The dams are currently undergoing removal; it is the largest such project ever attempted in the United States. The purposes of this experiment were to ...
Nutrient Concentrations and Distributions within the Lower Elwha River during Dam Removal
The objective of this research was to characterize nutrient concentrations and distributions throughout the Elwha River watershed, focusing on dissolved inorganic nitrogen (DIN), phosphorus and silicic acid. Previous research has indicated that the Elwha River is oligotrophic, however with the removal of the dams comes the ...
The distribution of particulate organic carbon and sediment in the Elwha River dispersal system during the dam removal process
The delivery and deposition of particulate organic carbon (POC) into the marine environment via rivers impacts local biological and geological processes as well as the global carbon cycle. This is especially the case in small mountainous rivers, such as the Elwha River, Washington, which delivers a significant fraction of ...
Using 7Be and textual characteristics to trace the source of sediment in the Elwha Delta
The removal of the two dams on the Elwha River provides a large-scale backdrop for sediment transport research. The demolition will stimulate sediment-laden flows downstream, directly impacting the Elwha delta and the marine environment. This study uses two different tracers to track sediment movement along the Elwha River ...
