Data Used to Characterize Peak Streamflows and Flood Inundation Resulting from Hurricane Harvey

In the immediate aftermath of Hurricane Harvey, the USGS and FEMA worked together to document the storm event in southeastern Texas and southwestern Louisiana.  This data release contains the flood inundation polygons, flood-depth rasters, mapped boundaries, and high-water mark (HWM) locations for the selected river basins...

Water-Quality Monitoring on Lake Houston

In cooperation with the City of Houston, USGS collects, processes, and interprets water-quality, streamflow, and reservoir water elevation and capacity data. These data are collected to better understand the effects of urbanization in Lake Houston...

Coastal Change Hazards Portal

Interactive access to coastal change science and data for our Nation’s coasts. Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Each data item represents an individual research product, with some items grouped together as aggregates to show the breadth of the topic and make it easy to explore.

Key Findings for Scenario-Based Assessment for Hurricanes

Percentage of sandy beaches very likely (probability > 0.9) to experience erosion associated with collision, overwash, and inundation during category 1-5 hurricane landfall.

Oblique Aerial Photography Viewer

Obique photos offer a unique perspective of the coast. Features such as beach erosion or accretion, dune erosion and overwash can all be clearly characterized in this imagery. It also documents coastal infrastructure, as well as the damage that infrastructure may incur as the result of an impacting hurricane.

Total Water Level and Coastal Change Forecast Viewer

Total water level (TWL) at the shoreline is the combination of tides, surge, and wave runup. A forecast of TWL is an estimate of the elevation where the ocean will meet the coast and can provide guidance on potential coastal erosion and flooding hazards.

USGS Flood Inundation Mapper

USGS Flood Inundation Maps , along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.

StreamStats Batch Processor Tool

This tool produces shapefiles that contain the delineated basins, basin characteristics, and flow statistics for multiple sites requested at once by users. Before this tool can be used, the the points of interest will likely need to be edited in GIS so that they are coincident with the stream grid used by StreamStats for delineations and saved to a shapefile.
