This model application data release contains a 3D hydrodynamic model of the San Francisco Bay and Sacramento-San Joaquin Delta constructed using the D-Flow Flexible Mesh hydrodynamic model code (D-Flow FM; Kernkamp and others, 2011). This model simulates water currents, surface elevations, salinity, and water temperatures throughout the San Francisco Bay and Delta (SFBD) in response to...

Two industry seismic-reflection profiles in Chuckwalla Valley (southeastern California) were donated by Buckhorn Petroleum to the CALCRUST program in ~1987. USGS personnel Jeff Wilson, Eric Geist, and Jill McCarthy reprocessed the seismic reflection data, concentrating on imaging reflections below the Cenozoic basin fill using pre-stack techniques. This data release describes the...

This data release contains traditional and portable optically stimulated luminescence (OSL) data collected from the Stinking Water Creek Basin near Rangely, Colorado, to constrain the timing of alluvial deposition and channel evolution in landscapes underlain by the Late Cretaceous Mancos Shale. The dataset includes OSL measurements from fluvial terraces, modern stream channels, and...

In July 2025, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected single-beam bathymetry (SBES) data and sediment vibracores at Lake Maggiore, St. Petersburg, Florida. These data were collected during USGS field activity number (FAN) 2025-309-FA. The SBES data were collected using USGS research vessel (R/V) MAKO. The...

These hazard data accompany revisions to the 2023 50-state National Seismic Hazard Model (NSHM; Petersen and others, 2024; Petersen and others, 2022 for Hawaii; Powers and others, 2024 for Alaska) as documented in Powers and others (2026). In these revisions, we: adjust the representation of ground motion model (GMM) epistemic uncertainty where the central and eastern U.S. (CEUS) stable

This data set includes vegetation response data from two salt marshes in Buzzards Bay, Massachusetts, which received hydrologic restoration to address interior ponding using runnels. These data are from a replicated BACI (before-after-control-impact) designed study. Data were collected using point-intercept method for percent cover, stem counts, stem height measurements, among other...

These data were collected as a part of a replicated BACI (before-after-control-impact) designed study to test the efficacy of restoration using runnels, at two marshes with differing hydrology and geomorphology. Data are from Buzzards Bay, Massachusetts. This data set includes field collected elevation data combined with tidal local tidal datums. These data were averaged over several...

This data set includes water level response data from two salt marshes in Buzzards Bay, Massachusetts, which received hydrologic restoration to address interior ponding using runnels. These data are from a replicated BACI (before-after-control-impact) designed study, at two marshes with differing hydrology and geomorphology. Data were collected using HOBO Water Level Data Loggers (U20L...

This single-band float32 GeoTIFF raster represents a spatially smoothed vulnerability index for sagebrush (Artemisia spp.) ecosystems at the northern extent of the sagebrush biome, spanning the US–Canada border region from north-central Montana into southeastern Alberta and southwestern Saskatchewan, with smaller portions of Wyoming, North Dakota, and South Dakota (approximately 46.0°N...

Coastal managers need robust projections of how sea-level rise (SLR), sediment availability, and management actions may alter estuarine habitats. We developed and calibrated WARMER-Coast, an intermediate-complexity modeling framework, to simulate tidal wetland evolution, assess potential upslope migration pathways, and evaluate management scenarios developed in consultation with local...

As part of the Clean Water Act, Section 319 authorizes funding that is distributed to Mississippi Department of Environmental Protection Agency to address nonpoint sources of pollution in the state of Mississippi. For this project, Weighted Regressions on Time, Discharge, and Season (WRTDS) models (Hirsch and others, 2010) were used to perform a trend analysis on nitrogen and phosphorus

Inventory description This data release consists of an inventory of runoff-generated postfire debris-flow observations compiled from burned areas across the western United States. The included table, “USGS_RG_PFDF_Inventory_v1.csv”, contains observations of postfire debris-flow response indicating whether a debris flow did occur (1) or did not occur (0) in a burned watershed in response...
