What happens to Mississippi River flows when coastal storm surge moves upstream?
DynamicSolutions | DCCM, in cooperation with Gaurav Savant at the U.S. Army Engineer Research and Development Center (ERDC), recently published a study in the ASCE Journal of Waterway, Port, Coastal, and Ocean Engineering examining the interaction between storm surge and flows on the Mississippi River.
Using a fully coupled Adaptive Hydraulics Model (AdH), the study found that local discharge decreases as water levels rise with the passage of storm surge due to a shift in net momentum flux. Researchers also found that the river’s discharge response following the surge depends on the availability of lateral relief to discharge stored mass.
The findings provide additional insight into the complex interaction between coastal and riverine processes and demonstrate the value of fully coupled hydrodynamic modeling for understanding these dynamic systems.
DynamicSolutions | DCCM combines applied research, advanced hydrodynamic modeling, and water resources engineering to help public agencies and project partners better understand complex riverine and coastal systems.
