The purpose of this study is to use historical hydrographic surveys to quantify bathymetric changes in the forebay channel area of ORLSS over the last 56 yr. The results from this comparison support an ongoing geotechnical study led by Mr. Lucas Walshire, U.S. Engineer Research and Development Center (ERDC), for the U.S. Army Corps of Engineers, New Orleans District (USACE MVN).

The Brunswick area consists of many acres of estuarine and marsh environments. The US Army Corps of Engineers District, Savannah, requested that the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory, develop a validated Adaptive Hydraulics model and assist in using it to perform hydrodynamic modeling of proposed navigation channel modifications. The modeling results are necessary to provide data for ship simulation. The model setup and validation are presented here.

This article discusses measures being taken by the U.S. Army Corps of Engineers to protect New Orleans from future flood events. The U.S. Army Corps of Engineers is redesigning and upgrading the 350-mile network of linked levees, floodwalls, gates, and pumps in the New Orleans area. The Corps of Engineers’ plan for New Orleans flood control involves upgrading some existing structures such as levees and floodwalls and adding some new risk-reduction features, two of which are movable gates. The proposed Bayou Bienvenue Gate will sit near the junction of the Gulf Intracoastal Waterway and the Mississippi River Gulf Outlet to keep floodwater away from the southern end of the Industrial Canal. The Seabrook Gate will span the northern end of the Industrial Canal where it meets Lake Pontchartrain. By preventing storm surges from entering the Industrial Canal, these gates will protect a densely populated residential and commercial area. However, the presence of the new gates will change day-to-day current patterns in ways that could impact existing structures and use.

Mobile Bay is a large estuary located in the southwest corner of Alabama, which connects to the Gulf of Mexico. Mobile Harbor contains the only port in the state that supports ocean-going vessels. Some of the larger vessels calling on the port experience transit delays and limited cargo capacity, so a study was conducted by the US Army Corps of Engineers, Mobile District (CESAM), and the Alabama State Port Authority to investigate channel improvements. In 2017, the US Army Engineer Research and Development Center (ERDC) assisted CESAM in screening proposed deepening and widening alternatives in Mobile Bay by completing a Feasibility Level Ship Simulation (FLSS) study using the ERDC Ship/Tow Simulator. These lower-resolution databases from the FLSS study were used as a foundation to complete a more robust navigation study in 2020 to test the proposed modifications to Mobile Harbor. During this study, three main areas were focused on: a bend easing, a passing lane, and a turning basin. Testing of the proposed design was evaluated over the course of 2 weeks with eight pilots. Assessment of the proposed modifications was accomplished through analysis of ship simulations completed by experienced local pilots, discussions, track plots, run sheets, and final pilot surveys.
