Borehole Erosion Test data, Lower American and Sacramento Rivers, California, 2019 (ver. 4.0, July 2021) Borehole erosion tests were performed to quantify sediment erosion rates as a function of depth below grade and flow speed at locations along the Sacramento and American Rivers in 2019. The dataset consists of: - borehole caliper files describing the initial geometry of the borehole, and its shape after each test flow event, - where available, a digital time series describing discharge into the hole - where available, a digital time series describing water level in the water supply tank - log sheets with details such as test location, date, and personnel - digital log sheets in .pdf format include field-based and laboratory-based soil classification data, see "Drilling log file explanation.txt" for explanation of...
