A generic, three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00) and MODPATH-6 (version 6.0.01), was created to better understand the amount of vertical flow and cross-contamination of trichloroethene (TCE) that may be occurring in discontinued extraction wells under current (2018-19) ambient-flow conditions at site 25 of the Edwards Air Force Base, California. The wells are long-screened (100-ft long), contain a surrounding sandpack, and have not been pumped for approximately 10 years. The groundwater flow model utilized multiple observations made from the field measurements of flow and transport to conceptualize, calculate, and simulate in-well flow, and flow in the sand pack. The model was...
The Southern Nevada volcanic-rock aquifers reside in southern-central Nevada. This group of aquifers can be categorized into welded tuff, bedded tuff, and lava flow aquifers. Each of these categories possess different physical characteristics and have varying degrees of welding and number of interconnected joints. The lithology of these aquifers is primarily dependent on mode of eruption and cooling and are highly variable. Because the lithology is so variable, so is groundwater transmission, storage, and yield (HA 730-B). This product provides source data for the Southern Nevada volcanic-rock aquifers framework, including: Extent shapefiles: 1. p_57SRNVDV.shp: Polygon shapefile containing the areal extent...

The Bank Stability and Toe Erosion Model (BSTEM) version 3.3.1 (Ursic and Langendoen, 2021) was used to predict bank retreat at five locations along Caulks Creek, Wildwood, Missouri, for a selection of design storm scenarios. BSTEM is a macro-enabled Excel spreadsheet (.xlsm file) that simulates the retreat of a bank profile due to a combination of fluvial and geotechnical processes. These BSTEM simulations build on hydrologic and hydraulic modeling of Caulks Creek for a wide variety of design storm scenarios that represent both current and future climate conditions (Heimann and others, 2024). The six design storm scenarios selected for BSTEM simulations include storms of 6-hour duration with 2-year (2yr), 10-year...

Hurricane Maria caused widespread landsliding throughout Puerto Rico during September 2017. Previous detailed landslide inventories following the hurricane include Bessette-Kirton et al. (2017, 2019). Here we continue that work with an in-depth look at a portion of northwest Naranjito, which is a municipality in the northeastern part of the main island. To study a characteristic sample of landslides in Naranjito, we mapped all visible individual landslides in an approximately triangular area 2.3 km wide by 1.9 km long. The boundary of our mapping was defined by previous studies (Bessette-Kirton et al., 2019). We used aerial imagery collected between 9-15 October 2017 (Quantum Spatial, Inc., 2017) to map landslide...
The U.S. Geological Survey (USGS), in cooperation with the Washington State Department of Ecology (Ecology), conducted a study to describe the current understanding of the regional groundwater system of the lower Duwamish River valley and groundwater and surface-water interactions in the lower Duwamish Waterway. A nearshore site along the western shoreline of the Duwamish River, about 1.5 mi upstream from the river mouth, was selected for focused groundwater data collection by USGS. Data loggers were deployed in seven groundwater wells and one stilling well in the Duwamish River to measure specific conductance, temperature, and depth at 15-minute intervals for a period of about 2 years.This data release contains...

This digital dataset contains the gridded future climate data used for the Lower Salinas Valley Hydrologic Models. The monthly climate data for Lower Salinas Valley Hydrologic Models are based on the Salinas and Carmel River Basins Study (SCRBS) future climate scenarios [Henson and others, 2024). SCRBS considers one baseline climate scenario that represents recent historical climate conditions and five future climate scenarios: Hot-Wet (HW), Warm-Wet (WW), Hot-Dry (HD), Warm-Dry (WD), and Central Tendency (CT) (Henson and others, 2024). To develop the monthly climate grids, the regional climate data was resampled to a monthly timescale and area weighted to the model grid. The climate data includes spatially distributed...
The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Boone and Roubidoux aquifers in northeastern Oklahoma by using MODFLOW-NWT (version 1.1.4) with the Newton formulation solver to simulate groundwater flow and account for the drying and rewetting of cells within the groundwater-flow model. The numerical groundwater-flow model was discretized into four layers consisting of 354 rows by 261 columns with a 2,000-feet by 2,000-feet cell size. The model layers were used to simulate the Western Interior Plains confining system, the Boone aquifer, the Ozark confining unit, and the Roubidoux aquifer. The...
We created a single map of surface water presence by intersecting water classes from available land cover products (National Wetland Inventory, Gap Analysis Program, National Land Cover Database, and Dynamic Surface Water Extent) across the U.S. state of Arizona. We derived classified samples for four wetland classes from the harmonized map: water, herbaceous wetlands, wooded wetlands, and non-wetland cover. In Google Earth Engine (GEE) we developed a random forest model that combined the training data with spatially explicit predictor variables of vegetation greenness indices, wetness indices, seasonal index variation, topographic variables, and hydrologic parameters. The final product is a wall-to-wall map of...

The Massachusetts Drought Management Plan (DMP, 2023) uses data from select lake and impoundment systems as an index for drought in six of seven regions in the state. The contents of these lakes and impoundments are reported to Massachusetts Department of Conservation and Recreation (DCR) and classified as one of five levels for drought severity ranging from level 0 (Normal; percentile greater than 30) to level 4 (Emergency; percentile less than 2). Lake and impoundment system data are provided at the end of each month to DCR through multiple agencies as lake levels, volumes, or percent-full (reservoir capacity). USGS reviewed data from 14 of the lake or impoundment systems including 28 waterbodies. Diagrams for...
