Morphodynamic Evolution of a Mississippi River Delta Sediment Diversion Channel

posted on 06.30.2016

Brendan Yuill, Author

This study employs a series of numerical modeling experiments to simulate flow and sediment dynamics within the West Bay study area. The objectives of the experiments were to identify [1] how changes in the channel morphology may have modified the flow field passing through the diversion during a range of steady discharges and [2] how those changes in the flow field would affect the diversion function (i.e., in terms of flow and sediment discharge). The experiments employed a time series of bathymetric data to define the diversion channel and receiving basin through time. ADCP velocity measurements and suspended sediment sampling helped guide model calibration. Model results are unlikely to precisely replicate past hydraulic environments; flow and sediment transport in estuarine areas are also significantly affected by waves, winds, and fluctuations in sediment supply – variables that were not considered by this study.

Hydraulic Response and Morphological Evolution at a Lower Mississippi River Channel Bar

posted on 06.30.2016

Brendan Yuill, Author

Brendan Yuill of The Water Institute, presented recent studies related to sand mining in the Lower Mississippi River at the American Geophysical Union Meeting in 2014.  Little is known about the rate at which borrow pits infill; this makes the max sustainable rate of sand mining uncertain. And while reach-scale effects of in-channel mining are well understood, the local effects are not – and these effects influence how and how long the borrow area and pit evolve.

Mississippi River Hydrodynamic and Delta Management Study: Data Collection Program

posted on 03.31.2014

Mead Allison, Author

Mead Allison, Director of Physical Processes and Sediment Systems, presented at State of the Coast 2014 held in New Orleans, November 18-20, 2014. This is a presentation of Mississippi Hydrodynamic and Delta Management Study data collection results done in tandem with the Federal partner (U.S. Army Corps of Engineers ERDC).  Outlines data collection sites, work performed to date, improvements in process understanding, utilization in modeling for formulation and parameterization, and plans for future research.

Integrated Approach to Assess and Formulate Restoration Measures in the Chenier Plain, LA

posted on 11.15.2013

Ben Roth, Author

Ben Roth, Research Associate at The Water Institute of the Gulf, presented at 22nd Biennial Conference of the Coastal and Estuarine Research Federation (CERF) held in San Diego, California November 3-7, 2013.  His presentation titled "Integrated Approach to Assess and Formulate Restoration Measures in the Chenier Plain, Louisiana". This presentation discusses the integrated modeling effort for the Chenier Plain.  Different types of models were utilized to understand different aspects of the system.  Compartment models provide planning-level analyses for multiple projects that influence basin-wide dynamics.  Spatially distributed models provide insight at a refined scale to assess short-term influences of proposed hydrologic and salinity control projects.  Together these models develop a more holistic approach to project planning and design efforts.
