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 the Federal Highway Administration, Hydraulic Engineering Circular No. 23, Bridge Scour and Stream Instability Countermeasures. To that end, the U.S. Geological Survey, in cooperation with the Federal Highway Administration, obtained bathymetric, topographical, and other data at 20 of the surveyed sites across the United States...

The US Fish and Wildlife Service has been petitioned to list the regal fritillary butterfly under the Endangered Species Act (ESA) with decision due in FY 2022. Population and species viability are directly related to genetic diversity, yet direct measures of genetic diversity are rare for any species, let alone a species of conservation concern. Previous research revealed regal fritillary populations show a reduction in genetic diversity from west to east, as potential habitat patches become smaller and more isolated. Genetic information will inform the species status assessment and the 12-month finding for this species.PI: Sara Oyler-McCance, sara_oyler-mccance@usgs.govPI/Funding recipients organization: US Geological...
