In 2012, the U.S. Geological Survey (USGS) in cooperation with Colorado Springs Utilities selected 10 study areas along Fountain Creek between Colorado Springs, Colorado and the confluence of Fountain Creek with the Arkansas River for annual geomorphic monitoring. The purpose of this data release is to present topographic survey data, rasters , and sediment size data collected in 2019 as part of that monitoring effort. Topographic survey points were collected using real-time kinematic Global Navigation Satellite Systems (RTK-GNSS). These point data were interpolated to generate digital elevation maps (2015 and 2019) and elevation-change maps (from 2015 to 2019) at each study area . In 2019, two types of Unmanned...
In 2012, the U.S. Geological Survey (USGS) in cooperation with Colorado Springs Utilities selected 10 study reaches along Fountain Creek between Colorado Springs, Colorado and the confluence of Fountain Creek with the Arkansas River for annual bed and bank characterization and topographic surveys. The 10 study reaches are approximately 5 to 20 bank-full channel widths in length. Data were collected in 2018 that are similar in method and scope as data collected from 2012 to 2017.Topographic survey points were collected using real-time kinematic Global Navigation Satellite Systems (RTK-GNSS). Pebble-count data were collected at all 10 study reaches and included 4 measurements of grain size at each of 25 equally spaced...

The domain of the model is as follows: Row River from Dorena dam to the confluence with the Coast Fork; Coast Fork from Cottage Grove dam to the confluence with the Middle Fork; Silk Creek from River Mile 1.7 to the confluence with the Coast Fork. The basis for these features is the Willamette Flood Insurance Study – Phase One (2013). The hydraulics and hydrology for the FIS were reused in the production of these polygons; the reports and information associated with the FIS are applicable to this product. The Digital Elevation Model (DEM) utilized for the Willamette FIS submittal was produced by combining multiple overlapping topographic surveys for the Middle Fork and Coast Fork of the Willamette River. This DEM...
Digital flood-inundation maps for a 10.2-mile reach of the Wabash River at Memorial Bridge at Vincennes, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Office of Community and Rural Affairs. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage on the Wabash River at Memorial Bridge at Vincennes, Indiana (station number 03343010). Near-real-time stages at this streamgage may be obtained from the USGS National Water Information System at http://waterdata.usgs.gov/...

In this report, we evaluate potential tsunami hazards for southeastern Alaska communities of Elfin Cove, Gustavus, and Hoonah and numerically model the extent of inundation from tsunami waves generated by tectonic and landslide sources. We perform numerical modeling of historic tsunami events, such as the tsunami triggered by the 1964 Great Alaska Earthquake, and the tsunami waves generated by the recent 2011 Tohoku and 2012 Haida Gwaii earthquakes. Hypothetical tsunami scenarios include variations of the extended 1964 rupture, megathrust earthquakes in the Prince William Sound and Alaska Peninsula regions, and a Cascadia megathrust earthquake. Local underwater landslide events in Taylor Bay and Port Frederick,...
7 aerial photographs were taken along the Little Missouri River in 1949. All images were geo-referenced to the 1995 digital orthophoto quarter quadrangles as described by Miller and Friedman (2009). Both the flood plain and active channel of the river were delineated on the 1995 digital orthophoto quadrangles and overlaid on rectified photos. ArcGIS was used to draw the polygons that delineate the flood plain and active channel; the delineation was saved as a SHP file. The separate images (geoTIFFs) can be viewed as a composite along with that year's channel delineation (SHP file) using a geographic information system (GIS) application.

The mapped area boundary, flood inundation extents, and depth rasters were created to provide an estimated extent of flood inundation along the Gauley River within the community of Camden-on-Gauley, West Virginia. These geospatial data include the following items: 1. gauley_bnd; shapefile containing the polygon showing the mapped area boundary for the Gauley River flood maps, 2. gauley_hwm; shapefile containing high-water mark points, 3. polygon_gauley_hwm; shapefile containing mapped extent of flood inundation, derived from the water-surface elevation surveyed at high-water marks, 4. depth_hwm; raster file for the flood depths derived from the water-surface elevation surveyed at high-water marks, 5. polygon_gauley_dem;...
This table contains information about the amount of each threat analysis attribute, indicator and metric quantified for the 6th level Hydrological Unit (HUC12). These attributes were calculated for the entire HUC 12, the streams within the HUC 12, or the riparian corridor within the HUC 12. The attributes were calculated using ArcMap Tools. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. The User is encouraged to carefully consider the content of the metadata file associated with these data.

Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). This "Child item" page includes videos of debris flows captured by one of the high-definition cameras at the monitoring site in Chalk Cliffs, CO. This camera (Bridge Camera) is located at Station 1 which is at the bridge cross section at the channel. The attached figure "station_and_camera_locations.png" provides an overview figure with the location of the two cameras and three stations along the channel. Video recording for all cameras is triggered using a rainfall threshold, derived from rainfall measurements from a rain gauge (Michel et al., 2019). The complete...

This data release consists of tables with the thickness and particle-size characteristics of overbank sediment deposited in May 1978 along the valley of Powder River in southeastern Montana. About 900 sediment samples were collected at regularly-spaced distances from 20 valley transects along a 90-kilometer reach of Powder River between Moorhead and Broadus, Montana. The decrease in sediment thickness and particle size with distance from the main channel showed weak trends, which were caused by the variability introduced by vegetation sediment traps and subsidiary channels.

Chalk Cliffs, located 8 miles southwest of Buena Vista, CO, is one of the most active debris-flow areas in the state (U.S. Geological Survey, 2020). This "Child item" page includes videos of floods captured by one of the high-definition cameras at Chalk Cliffs. This camera was placed at the Firehose Station which is located on the perimeter of the study area at the base of the cliffs and was used to monitor the impacts of cascading water runoff during rainstorms on loose sediment at the cliff base. The Firehose station was also used to constrain the sediment concentration of flows impacting sediment at the base of the cliff. It was equipped with a rain gage and video camera to record flow characteristics. See figure...
Digital flood-inundation maps for a 9.3-mile reach of the Iowa River along the Meskwaki Settlement, Iowa, were created by the U.S. Geological Survey (USGS) in cooperation with the Sac and Fox Tribe of the Mississippi River in Iowa. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science web site at https://water.usgs.gov/osw/flood_inundation/ depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage 05451770 on the Iowa River at County Highway E49 near Tama, Iowa. Near-real-time stages at this streamgage may be obtained on the internet from the USGS National Water Information System at https://waterdata.usgs.gov/...
