| Description: | Technical report The U.S. Army Engineer Hurricane Protection Office (HPO) requested that the USACE Engineer Research and Development Center (ERDC) perform a numerical modeling study for the purpose of analyzing the impacts of proposed hurricane and storm damage risk reduction system (HSDRRS) measures to be placed in the Gulf Intracoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO) on the larval fish transport in the area. This study was requested in addition to separate navigation studies to analyze the impacts the protection measures have on the hydrodynamics and vessel traffic. It is known that larval fish migrate from the Gulf of Mexico into Lake Pontchartrain. A particle tracking simulation can be performed such that the particles are given basic larval fish transport behaviors and released at various locations in the area. The hydrodynamic processes move these particles within the system and the changes to the transport due to the planned changes to the system can be analyzed. The model is validated with field data from 2008 of water surface elevation, discharge, and velocity. Four plan simulations are modeled in addition to the base condition. Transport of particles within the system is dominated by the hydrodynamics of the system. The tidal intensity and regularity of the tidal signal are a main factor of transport. Particles released during stronger events may be recruited at a greater rate than a less intense flow condition. However that is additionally affected by the larval fish characteristic transport behaviors. |
