Closed depression density in karst regions of the conterminous United States: features and grid data

Most methods for the assessment of sinkhole hazard susceptibility are predicated upon knowledge of pre-existing closed depressions in karst areas. In the United States (U.S.), inventories of existing karst depressions are piecemeal, and are often obtained through inconsistent methodologies applied at the state or county level and at various scales. Here, we present a first attempt at defining a ka

Community Exposure in California to Coastal Groundwater Hazards Enhanced by Climate Change, reference year 2020

The data set contains information on potential population, economic, land cover, and infrastructure groundwater inundation exposure for San Francisco Bay and coastal communities of the state of California, USA. The type of information includes U.S. Census data on the number and types of residents, Data Axle data on numbers and types of employees, county parcel values, HAZUS building replacement va

Selected sediment data and results from regression models, modified Einstein Prodecure, and loads estimation for the Nemadji River, 1973-2016

This data set includes new and historical sediment data collected at the U.S. Geological Survey (USGS) streamgage on the Nemadji River near South Superior, Wisconsin (station number 04024430) from 1973 through 2016. The data were used in a comparison study of stream sediment collection and laboratory techniques for characterizing suspended sediment, bedload, and total sediment loads. Data results

Integrated modeling of climate and land change impacts on future dynamic wetland habitat – a case study from California’s Central Valley

This dataset consists of raster geotiff and tabular outputs of annual map projections of land use and land cover for the California Central Valley for the period 2011-2101 across 5 future scenarios. Four of the scenarios were developed as part of the Central Valley Landscape Conservation Project. The 4 original scenarios include a Bad-Business-As-Usual (BBAU; high water, poor management), Californ

Short Term Vegetation Response Study at Watershed Restoration Structures in Southeastern Arizona, 2015 - 2019

This dataset contains vegetation data collected at a variety of watershed restoration sites across southeastern Arizona over 5 years. The semiarid habitats in the Madrean Archipelago Ecoregion, which extends from southern Arizona into northern Mexico, are facing many challenges from climate change to land use change which threaten the ecological and cultural values of the region. Watershed restora

DSWEmod surface water map composites generated from daily MODIS images - California

USGS researchers with the Patterns in the Landscape ? Analyses of Cause and Effect (PLACE) project are releasing a collection of high-frequency surface water map composites derived from daily Moderate Resolution Imaging Spectroradiometer (MODIS) imagery. Using Google Earth Engine, the team developed customized image processing steps and adapted the Dynamic Surface Water Extent (DSWE) to generate s

Community Exposure in California to Coastal Flooding Hazards Enhanced by Climate Change, reference year 2010

The data set contains information on potential population, economic, land cover, and infrastructure flooding exposure for San Francisco Bay and coastal communities of the state of California, USA. The type of information includes U.S. Census data on the number and types of residents, InfoGroup USA data on numbers and types of employees, county parcel values, HAZUS building replacement values, NLC

Sediment mobility and river corridor assessment for a 140-km segment of the mainstem Klamath River below Iron Gate Dam, CA - vegetation mapping

This report documents river response to hydrologic disturbance along a 140-km segment of the mainstem Klamath River below Iron Gate Dam, CA by assessing fundamental indicators of active sediment transport and dynamic changes in riparian vegetation. A combination of field and remote sensing methods were used to document river response to natural rainfall-runoff events (e.g., 2006 and 2017) and mana

Influence of demand and capacity in transportation simulations of short-notice, distant-tsunami evacuations

Distant tsunamis require short-notice evacuations in coastal communities to minimize threats to life safety. Given the available time to evacuate and potential distances out of hazard zones, coastal transportation planners and emergency managers can expect large proportions of populations to evacuate using vehicles. A community-wide, short-notice, distant-tsunami evacuation is challenging because

Pedestrian tsunami evacuation results for three California probabilistic tsunami hazard zones and four travel speeds (shapefiles) and impaired walk travel times for all zones by parcel land-use and flow depth class (tables)

These datasets supports the conclusions in the journal article entitled "Variations in community evacuation potential related to average return periods in probabilistic tsunami hazard analysis" as described in the abstract below: Tsunami risk management requires strategies that can address multiple sources with different recurrence intervals, wave-arrival times, and inundation extents. Probabilis

Data release associated with the journal article "Solar and sensor geometry, not vegetation response, drive satellite NDVI phenology in widespread ecosystems of the western United States"

This dataset supports the following publication: "Solar and sensor geometry, not vegetation response, drive satellite NDVI phenology in widespread ecosystems of the western United States" (DOI:10.1016/j.rse.2020.112013). The data release allows users to replicate, test, or further explore results. The dataset consists of 4 separate items based on the analysis approach used in the original publicat

Mapped fire perimeters from the Sky Island Mountains of US and Mexico: 1985-2017

Polygon locations of fire perimeters in the Sky Island mountain ranges in the Madrean Archipelago Ecoregion of the southwestern United States and northern Mexico. These fires occurred from 1985 to 2017 and were mapped using Landsat satellite imagery.
