  Quantifying suspended-sediment load and transport characteristics in the Calawah and Upper Bogachiel Rivers, Washington

  The issue: Salmonid fisheries are an important cultural and economic activity and efforts to support a thriving fisheries industry remain a major priority for the Quileute Tribe on the Olympic Peninsula, Washington. Land use changes can have a profound influence on basin sediment production with direct effects on fisheries (Madej and Ozaki, 2009). Studies are needed to improve estimates of the...

  Suspended-Sediment Data for the Bogachiel and Calawah Rivers, WA for Water Years 2019-2021

  This data release summarizes suspended sediment monitoring results on the Bogachiel (USGS 12042800) and Calawah (USGS 12043000) Rivers between water years 2019 and 2021, based on a combination of continuous turbidity monitoring and discrete suspended-sediment concentration (SSC) measurements. Data and results for each monitoring station were combined into zip files. Each zip file contains:   Summ

  Supporting Spatial Data for Sediment Studies in the Bogachiel and Calawah River Watersheds, Washington

  This Data Release provides spatial data to support analysis of land cover change and channel width change in the Bogachiel and Calawah River basins, Washington. This supports a larger analysis that quantifies suspended-sediment yields for the two basins for water years 1977-1978 and more recently, for water years 2019-2021. Collectively the study evaluates influences of hydrology, geology, fire, a

  Changes in suspended-sediment yields under divergent land-cover disturbance histories: A comparison of two large watersheds, Olympic Mountains, USA

  Improvements in timber harvest practices and reductions in harvest volumes over the past half century are commonly presumed to have reduced sediment loads in many western US rivers. However, direct assessments in larger watersheds are relatively sparse. Here, we compare 2019–21 sediment concentrations against those of the late 1970s in the Bogachiel and Calawah  River watersheds, adjacent and simi
