Streambed Stability and Scour Potential at Selected Bridge Sites in Michigan
This report describes (1) the historical variability in streambed elevations on the basis of data collected in connection with routine streamflow measurements at 13 sites, (2) trends in aggradation and degradation of streambed elevations as indicated by the 40 or more historical streamflow measurements at each site, and (3) the relation between streamflow and streambed elevations as in as indicated by historical streamflow measurement data. The report summarizes results of geophysical surveys near four selected bridge sites to conditions. Finally, the report presents scour potentials associated with 100-yr floods computed from semi-theoretical equations and procedures recommended for nationwide use by Federal Highway Administration (FHWA), and compares empirical measures of streambed stability in Michigan with scour-potential estimates computed by use of equations and procedures recommended by FHWA.
