Lake Pontchartrain and Vicinity Hurricane Protection Plan. Report 3. Numerical Model Investigation of Plan Impact on the Tidal Prism of Lake Pontchartrain

摘要

A comprehensive study to evaluate effects of the Lake Pontchartrain and Vicinity Hurricane Protection Plan on the tidal prism and circulation in Lake Pontchartrain, hurricane surge levels, and water quality is being conducted by the U.S. Army Engineer Waterways Experiment Station (WES) under sponsorship of the U.S. Army Engineer District, New Orleans (LMN). Results of this study are to be presented in a series of reports published under the general title 'Lake Pontchartrain and Vicinity Hurricane Protection Plan.' The major tool employed in the numerous investigations carried out in the course of this study is a numerical hydrodynamic model (WES Implicit Flooding Model, WIFM), developed at WES, which is capable of simulating both tidal effects and hurricane surge flooding. This report, the third of the series, presents results pertinent to a detailed investigation of effects of proposed structures in the two major arteries (The Rigolets and Chef Menteur Pass) connecting Lake Pontchartrain with the Gulf of Mexico and the lock/structure system between the lake and the Inner Harbor Navigation Canal (IHNC or Seabrook Canal).
