Abstract

AbstractUpper Mississippi River flow and sediment characteristics downstream of St. Louis are presented in this study. Available and measured data were used to assess a harbor siltation case and dr...

  • Sediment characteristics and loads in the Mississippi River have been the subject of numerous studies in the past decades

  • The analyses showed that harbor siltation correlates with river conditions, and is driven by wash load in the river, which enters the harbor in suspension and deposits along the bottom due to the lack of flow-through velocities high enough to keep the fine sediments in suspension

  • Flow and sediments in the Upper Mississippi River were characterized with information available at the United States Geological Survey (USGS) gaging station in St
