Description

Title: The Proposed Mid-Breton Sediment Diversion Presenters: Matt Hoy Abstract: Historically, sediment-rich water overflowed the banks of the Mississippi River and moved through coastal Louisiana, nourishing healthy wetlands. However, these overflows no longer occur. Resulting subsidence, combined with several other factors, results in the loss of a football field of land every 100 minutes in these areas. The purpose of the Mid-Breton Sediment Diversion project is to provide a resilient, sustainable strategy to deliver sediment, freshwater, and nutrients to the Breton Sound Basin in order to create, preserve, restore, and sustain these wetlands. The Mid-Breton Sediment Diversion project is a gated diversion system being designed to divert approximately 50,000 cubic feet of water per second, or 5 percent of the Mississippi River during high flows, through existing levees to the Breton Sound. Stantec Consulting Services Inc., along with subconsultant Baird, is leading the design effort. Extensive field data collection and engineering analyses have been conducted to help determine the location of the inlet and the configuration of the corridor through which the diversion system will operate. This presentation will focus on the project background, preliminary analyses, in-river data collection and hydraulic modeling used to site and design the project. Bio (Hoy): Mr. Hoy is a Senior Principal with Stantec Consulting Services Inc. in St. Louis, Missouri. He received his BS and MS in Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign, where his master’s thesis was related to unsteady numerical modeling. He has over 15 years of experience in the analysis, design and management of water resources projects across the United States. Mr. Hoy uses his background in hydraulic and sediment transport modeling to pursue and manage the hydraulic analyses on large, interdisciplinary planning and design projects, including flood risk reduction studies, stormwater master plans, and coastal and ecosystem restoration. Lunch will be at noon, with socializing starting at 11:30.
