Vessel traffic and river environment descriptor variables have been listed and the magnitudes of their ranges defined. Target physical variables were selected on the basis of their likelihood of having biological effects. The total number of variables is 34, not including several basic quantities like water density and viscosity, which were introduced in a discussion of dimensional analysis. Dimensional analysis was used as a rational approach to a conceptual model of the physical impacts of navigation on constructed waterways. Eight parameters characterizing the physical effects of tow passages were discussed in detail. Because of its complexity, special attention was given the effects of the propulsion system....
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.
