This data release contains monthly 270-meter resolution Basin Characterization Model (BCMv8) climate and hydrologic variables for Localized Constructed Analog (LOCA; Pierce et al., 2014)-downscaled Global Climate Models (GCMs) for Representative Concentration Pathway (RCP) 4.5 (medium-low emissions) and 8.5 (high emissions) for hydrologic California. The 20 future climate scenarios consist of ten GCMs with RCP 4.5 and 8.5 each: ACCESS 1.0, CanESM2, CCSM4, CESM1-BGC, CMCC-CMS, CNRM-CM5, GFDL-CM3, HadGEM2-CC, HadGEM2-ES, and MIROC5. The LOCA climate scenarios span water years 1950 to 2099 with greenhouse-gas forcings beginning in 2006. The LOCA downscaling method has been shown to produce better estimates of extreme...

The U.S. Geological Survey (USGS) developed one-dimensional U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models for selected stream crossing sites in the Squannacook River Basin, north-central Massachusetts. A Geographic Information System (GIS) was developed to derive model input data from Light Detection and Ranging (lidar) Digital Elevation Models (DEM) at each stream crossing location. Hydraulic models were built for existing culvert designs as well as preliminary culvert designs for a 3-sided box, 3-sided arch, and a pipe culvert using field survey and GIS data. The preliminary culvert models were designed to convey the 10- and 4-percent annual...

A groundwater Nitrate Decision Support Tool (GW-NDST) for wells in Wisconsin was developed to assist resource managers with assessing how legacy and possible future nitrate leaching rates, combined with groundwater lag times and potential denitrification, influence nitrate concentrations in wells (Juckem et al. 2024). The GW-NDST relies on an ensemble of calibrated parameters to make nitrate predictions and to estimate the uncertainty of those predictions. This data release contains all of the calibrated parameter files required to run the tool. The files are packaged in a single ZIP file. To run the tool, the ZIP package needs to be downloaded and extracted within the pest/ies_parameter_ensembles/ subdirectory...
The U.S. Geological Survey (USGS) National Extent Hydrogeologic Framework for National Water Census (NEHF) project is a multi-year effort (2022 through 2025) that will compile existing assets (approaches, data, software, etc.), develop a strategic plan, and implement an operational framework that is dynamic and multi-scale. Within the USGS, numerical groundwater-flow and solute- and heat-transport models have been created for a variety of purposes that include water-resource assessments, contaminant-transport evaluations, and water-management planning. These models are often supported by hydrogeologic-framework studies that describe the surface and subsurface distribution of geologic materials and their hydrologic...

The Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST Warner and others, 2019; Warner and others, 2010) model was used to simulate three-dimensional hydrodynamics and waves to study salinity intrusion in the Delaware Bay estuary for 2019. Salinity intrusion in coastal systems is due in part to extreme events like drought or low-pressure storms and longer-term sea level rise, threatening economic infrastructure and ecological health. Along the eastern seaboard of the United States, approximately 13 million people rely on the water resources of the Delaware River basin, which is actively managed to suppress the salt front (or ~0.52 daily averaged psu line) through river discharge targets. However, river discharge...

This data release includes output data from the transit-loss accounting program for the Fountain and Monument Creek watersheds in El Paso and Pueblo Counties, Colorado. The output data distinguish between native and reusable streamflow. Native streamflow is that which originates naturally within the watershed. Reusable streamflow originates as water imported from outside the watershed, water derived from pumping of certain groundwaters, or as other water with rights that allow it to be reused. The program accounts for reusable water throughout the watershed, as well as the total inflow and outflow of water to each subreach division within the watershed. The accounting program is based upon stream-aquifer models...

This page contains results from 304 Fluvial Egg Drift Simulator (FluEgg; version 4.1.1) simulations of invasive carp eggs and larvae in the Maumee River, Ohio, under unsteady flow conditions. FluEgg models the drift and dispersion of eggs and larvae in fluvial environments. The eggs develop, changing in size and density, and eventually hatch into larvae. The simulations end when the larvae reach the gas bladder inflation stage or when the set duration of the simulation is exceeded (whichever comes first). FluEgg requires the user to provide hydraulic data to drive the drift model. The hydraulic inputs for these FluEgg simulations were generated using a one-dimensional unsteady hydraulic model of the Maumee River...

The U.S. Geological Survey simulated the drift and dispersal of invasive carp eggs and larvae in the Maumee River, Ohio, using the Fluvial Egg Drift Simulator (FluEgg) (Garcia and others, 2013; Domanski, 2020). The hydraulic inputs used in the FluEgg simulations were generated using a one-dimensional Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.7 model of the Maumee River (HEC-RAS, 2020). HEC-RAS simulations and FluEgg simulations were run for both steady and unsteady flow conditions. This data release contains an archive of the relevant files to document and run the HEC-RAS and FluEgg simulations of the Maumee River as well as the simulation outputs.

Spatial data layers of stream crossing point locations, cross-section polyline, centerline polyline, and bank polyline shapefiles have been developed for selected stream crossings in the Squannacook River basin, Massachusetts. The spatial data and calculated attribute values are model input data for U.S. Army Corps of Engineer’s Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models. The stream crossing point locations were derived from the North Atlantic Aquatic Connectivity Collaboration (NAACC) database. The stream channel cross-sections, centerlines, and bank polylines were derived using automated methods in a Geographic Information System (GIS) using ArcGIS Pro and Python programming...
