Exception: Upstream < Downstream downstream < St. Louis, MO
Sudden Increase of Sediment Concentration Near St. Louis, MO St. Louis Missouri River, major sediment supplier for MS Mississippi River
Missouri River: Results St. Louis Upstream has much larger concentration to discharge ratio;
Missouri River: Results St. Louis Upstream has much larger concentration to discharge ratio; The ratio increases near Sioux, IA and Omaha, NE.
Conclusions Sediment concentration to discharge ratio decreases downstream; Missouri River contributes a significant amount of sediment into the Mississippi River upstream of St. Louis, MO; Rivers are not at their full transport capacity most of the time.
Future Work Understand the physics of the observed trends; Study more rivers to verify those findings.
