Furrow infiltration and erosion data 1998 to 2016

The data are derived from the field monitoring of irrigated furrows from 1998 to 2016 at the research farm of the USDA/ARS-NorthWest Irrigation and Soil Research Laboratory in Kimberly, Idaho, U.S. For each monitored furrow, irrigation inflow rates, outflow rates, and sediment concentrations were recorded periodically during the irrigation. The field data for each study or year were analyzed using the WASHOUT program (Lentz and Sojka, 1995). The WASHOUT program produces an output file (filename.out), which become components of this Ag Data Commons data set. Data from many years and irrigations, furrows were measured at one or more locations along the furrow, as well as at the end (bottom) of the furrow. For each furrow position the data represent the flow, infiltration, and runoff information for the length of furrow, which begins at its inflow end (top of the field) and ends at the defined furrow position. This length is listed in the field data file for each furrow and irrigation. An ‘Irrigation Data Summary’ is included as a tab in the data set spreadsheet. This is a summary list of the studies and irrigations that are included in the data set. Also included is a PAM-Application-Codes tab that lists description of the polyacrylamide (PAM) treatments that were employed in some of the included studies.
