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...

USGS Science Data Catalog (SDC),
This data release consists of information from published tables in Connecticut Water Resources Bulletins (WRBs) transcribed into tabular digital format. Information about wells and test holes in the WRBs used in this data release consists of geographic location, depth to consolidated rock (bedrock depth), and depth of the well or test hole. The WRBs, published between 1966 and 1980 by the U.S. Geological Survey (USGS) in cooperation with either the Connecticut Water Resources Commission or the Connecticut Department of Environmental Protection, provided the foundational datasets for companion interpretive USGS Water-Resources Investigation Reports. NOTE: Version 2.0 adds 196 records but is otherwise identical to...
