This point data set contains streamflow-measurement sites in the Elkhorn and Loup River basins and selected streamflow-measurement sites in the Niobrara and Platte River basins in north-central Nebraska. At these 531 sites, flows ranging from no flow to 2,600 cubic feet per second were measured or observed during November 8 to 21, 2006. Measurements were made by several different methods, including current meters, flumes, and acoustic...

The U.S. Geological Survey, in cooperation with the North Platte Natural Resources District, used two surface geophysical techniques, capacitively coupled and direct-current continuous resistivity profiling, to map near-surface lithologies beneath the Interstate and Tri-State Canals in the spring and summer of 2004. This coverage represents the average electrical resistivity of sediments within the upper 8 meters below selected parts...

This digital data set defines the altitudes of the tops of 16 model layers simulated in the Death Valley regional ground-water flow system (DVRFS) transient flow model. The area simulated by the DVRFS transient ground-water flow model is an approximately 45,000 square-kilometer region of southern Nevada and California. The thickness of model layers is derived by sequentially subtracting the altitudes of the uppermost to the lowermost...

A numerical groundwater flow model using MODFLOW-2005 was developed to examine predevelopment groundwater flow in eastern Abu Dhabi Emirate, United Arab Emirates. The model was calibrated to conditions before the 1960s, the period before modern pumping began. The model was used to evaluate the regional water budget and 4 potential recharge scenarios. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (https://doi.org/10.3133/sir20185158). This data release also includes input and output data files for sensitivity and scenarios simulations, and MODFLOW-2015 source code.
