Climate change scientists have noted changes in Pacific Northwest hydrology, including reductions in the size of glaciers, less snowpack, and earlier peak stream flow in many rivers. These trends are expected to continue, along with increasing flood size, and decreasing summer low flows. Typically, the size of water-crossing structures like culverts and bridges is based on stream width. As the size of floods increases, so will stream width. WDFW’s web application can help you understand how the stream width at your project site may change in the future -- the 2040s and 2080s. With this information, you can make an informed decision about the design of your new culvert, bridge, or habitat restoration project. Culverts...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
