Upper Brown's Bar

The purpose of the Upper Brown’s Bar model study was to perform a comprehensive analysis of river engineering measures that would reduce or eliminate repetitive dredging between River Miles 25.00 to 23.75 and produce a report that communicates the results of the HSR model study.

The goals of this study were to: 

  • Investigate and provide analysis on the existing flow mechanics causing the sedimentation problems.
  • Evaluate a variety of remedial measures utilizing an HSR model with the objective of identifying the most effective and economical plan to reduce or eliminate sedimentation from RM 25.00 to RM 23.50. In order to determine the best alternative, 3 criteria were used to evaluate each alternative.
    • The alternative should reduce or eliminate sedimentation between RM 25.00 and RM 23.50.
    • The alternative should maintain the navigation channel requirements of at least 9 foot of depth and 300 foot of width.
    • The alternative should not significantly impact existing environmental features within the reach.
  • Communicate to other engineers, river industry personnel, and environmental agency personnel the results of the HSR model tests and the plans for improvements.
