IHNC Lake Borgne Surge Barrierとは 意味・読み方・使い方

The Inner Harbor Navigation Canal Lake Borgne Surge Barrier is a storm surge barrier under construction near the confluence of and across the Gulf Intracoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO) near New Orleans. The barrier runs generally north-south from a point just east of Michoud Canal on the north bank of the GIWW and just south of the existing Bayou Bienvenue flood control structure. Navigation gates will be constructed where the barrier crosses the GIWW and Bayou Bienvenue to reduce the risk of storm surge coming from Lake Borgne and/or the Gulf of Mexico. Another navigation gate (Seabrook Floodgate) is planned for the Seabrook vicinity where the IHNC meets Lake Pontchartrain to block a storm surge from entering the IHNC from the lake.
