This data release contains inputs for and outputs from hydrologic simulations of the upper Chattahoochee River Basin in northeast Georgia using the Precipitation Runoff Modeling System (PRMS). These simulations were developed to provide example applications of enhancements to the PRMS for the following topics: two new time-series input options (dynamic parameter module and water-use module), two new output options (Hydrologic Response Unit (HRU) summary output module and basin variables summary output module), and three updates of existing capabilities (stream and lake flow routing module, surface-depression storage and flow simulation, and the initial-conditions specification). These PRMS model input and output...

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitoring has been conducted on streams and rivers throughout the Nation. Outside of the NAWQA project, the USGS also has collected long-term water-quality data to support additional assessments of changing water-quality conditions. These data have been combined to provide insight into how natural features and human activities have contributed...

In August 2015, water velocities around a fully-loaded commercial barge tow were measured as the barge tow traveled upstream through the Chicago Sanitary and Ship Canal from a starting position in Lockport Pool, and passed through the Electric Dispersal Barrier System at river mile (RM) 296 near Romeoville, IL. Velocity measurements were made in and alongside the gap formed by the junction between the boxed stern of a rake hopper barge and the raked bow of a rake tanker barge (herein referred to as the rake-to-box junction gap) using two SonTek Argonaut SW 3kHz acoustic Doppler velocity meters (ADVM). One ADVM was mounted 0.091 meters below the water surface, facing downward in the center of the rake-to-box junction...
This data set archives all inputs, outputs and scripts needed to reproduce the findings of W.H. Farmer and R.M. Vogel in the 2016 Water Resources Research article entitled "On the Deterministic and Stochastic Use of Hydrologic Model". Input data includes observed streamflow values, in cubic feet per second, for 1225 streamgages over the period from 01 October 1980 through 30 September 2011. Estiamted streamflows, for the same streamgages and periods, is provided from a general calibration of the Precipitation Runoff Modeling System. Output data includes the same with alternate realizations of streamflow generated following the descriptions in the associated report. These results can be regenerated by using the included...

This USGS data release represents the input data used to identify trends in New Jersey streams, water years 1971-2011 and the results of Weighted Regression on Time, Discharge, and Season (WRTDS) models and seasonal rank-sum tests. The data set consists of CSV tables and Excel workbooks of: • trends_InputData_NJ_1971_2011: Reviewed water-quality values and qualifiers at selected stream stations in New Jersey over water years 1971-2011 • trends_WRTDS_AnnualValues_NJ_1971_2011: Annual concentrations and fluxes for each water-quality characteristic at each station from WRTDS models • trends_WRTDS_Changes_NJ_1971_2011: Changes and trends in flow-normalized concentrations and fluxes determined from WRTDS models •...
