Gust Erosion Chamber Data, Yolo Bypass, CA (2015-16)

A Gust erosion chamber was used to apply horizontal shear stress to sediment cores obtained at selected locations within the Yolo Bypass near Sacramento, California. The locations correspond to different land uses; two cores were taken at each site. The shear stress was increased in stepwise fashion, and turbidity of the effluent monitored. From this, two quantities are calculated: 1) critical shear stress required to initiate erosion, and 2) soil mass eroded per square meter at an applied shear stress of 0.4 Pa. So for each core we have a date, land use or site, core number, latitude, longitude, critical shear stress, and tau_0.4.
