Geospatial Data for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016–18

Scouring of streambed material surrounding bridge structures is a leading cause of bridge failure in the United States. Damages resulting from bridge failure oftentimes lead to financial burdens and loss of life. To date, there has been no comprehensive evaluation of the current (2016) effectiveness of the guidance or overall long-term performance of bridge-scour countermeasures provided in...

Point-Source Nutrient Loads to Streams of the Conterminous United States, 2012

The U.S. Geological Survey (USGS) developed a spatial water-quality model called SPAtially Referenced Regressions On Watershed attributes (SPARROW) to estimate the major sources and environmental factors that affect the long-term supply, transport, and fate of contaminants in the Nation’s streams. The SPARROW model relates in-stream water-quality data to spatially referenced c

Particle Size Analysis for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2014-18

These data are supplemental rip-rap gradation data (Wolman Pebble Count) in text (.txt) format, collected during 2014-2018 field seasons for select bridges in the United States. These data were collected using a measuring tape to determine riprap gradation (D15, D50, D85, and D100) on in-place riprap at bridge piers and/or abutments at various locations in each study reach.

Flume Conditions During a Laboratory Assessment of Alternative Stream Velocity Measurement Methods

The USGS Idaho Water Science Center (IDWSC) recently completed a report (citation TBD) documenting methods for alternative stream velocity measurement methods. The methods developed can be used to provide low-cost estimates of stream velocity as a component to estimate total streamflow at remote sites. This data release presents data from a laboratory assessment of alternative stream velo

Site Information for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016-18

These data are supplemental site information in portable document format (.pdf) collected during 2016-2018 field seasons for select bridges in the United States (Dudunake and others, 2018). These files describe building plans for countermeasures, a field from to describe conditions during site assessment, and a photo summary of the study area.

American Falls Reservoir Bathymetry (Elevation Vectors) near River Mile 713 to 714, Power County, Idaho, 2019

The USGS, in cooperation with the U.S. Bureau of Reclamation, surveyed the bathymetry within an area of about 500 acres of American Falls Reservoir between River Miles 713 and 714 during the week of August 6-8, 2019. The bathymetric survey provided high resolution detail of a proposed treatment area for an aeration system that is being developed to support water quality during the American

Bathymetry of Blackfoot Reservoir, Caribou County, Idaho, 2011

The USGS, in cooperation with the Shoshone-Bannock Tribes, surveyed the bathymetry of Blackfoot Reservoir in 2011 to determine temporal changes due to sedimentation and other factors, and to improve the overall accuracy of the stage-capacity table. Bathymetric surveys of high accuracy and resolution are possible through advances in instrumentation, notably a multibeam echosounder (MBES%
