Model Archive Summary for Acoustic Derived Suspended Fines Concentration at 14246900 Columbia River at Port Westward NR Quincy, OR

This model archive summary documents the suspended fines (grain sizes < 0.0625mm) concentration model developed to compute 5-minute suspended fines concentration data of the Columbia River at Port Westward, near Quincy, OR, U.S. Geological Survey (USGS) site number 14246900. The methods used follow USGS guidance as referenced in USGS Techniques and Methods, Book 3, Chap. C2 (Edwards and others, 1999); Office of Surface Water Technical Memorandum (TM) 2016.07 (USGS, 2016); Office of Water Quality TM 2016.10; USGS Techniques and Methods, book 3, chap. C5 (Landers and others, 2016); and USGS Techniques and Methods, book 3, chap. C4 (Rasmussen and others, 2009). The time series suspended sediment data will help determine the suspended sediment concentration at the site in real-time enabling science entities, managers, and others, track the movement of sediment in the Columbia River.
