NOAA - Great Lakes Environmental Research Laboratory In addition, a vertical seawall on the south shore of the lake tends to reflect a high degree of wave energy back into the lake in the vicinity of the lock site. Dominant period 4 seconds. TONIGHT West winds 5 to 10 knots. Two buoys in the Gulf of Mexico were close to the pathway of Hurricane Katrina; one buoy capsized and last recorded waves of 10.5m, the other buoy recorded the waves throughout the passing of the storm and found significant wave heights to be 16.9m.

GMZ530-082215- Lake Pontchartrain and Lake Maurepas- 328 AM CST Tue Dec 8 2020 TODAY Northeast winds near 5 knots becoming west in the late morning and afternoon. waves in Lake Pontchartrain (ranging up to 5 ft in height) approaching from northwest, north-northwest, and north. For these reasons, the height of the waves in Lake Pontchartrain will never be more than approximately 4 to 5 feet, and wave length (from top to top) not more than 20 feet during strong winds. Lake Pontchartrain (/ ˈ p ɒ n tʃ ə t r eɪ n / PAHN-chə-trayn; French: Lac Pontchartrain, French: [lak pɔ̃ʃaʁtʁɛ̃] ()) is a brackish estuary located in southeastern Louisiana in the United States. It covers an area of 630 square miles (1,600 km 2) with an average depth of 12 to 14 feet (3.7 to 4.3 m).Some shipping channels are kept deeper through dredging.

Flood Recovery Guidance Method – Freeboard For areas north and west of Interstate 10 and along Lake Pontchartrain, the Advisory BFE is the effective BFE plus a Wave height (m) Wave period (s) Tide type. Occasional wave height is the average of the highest 1/10 of the wave spectrum. Historic Crests (1) 9.00 ft on 08/18/1969 (2) 5.41 ft on 08/05/2002 (3) 3.37 ft on 07/30/1995 (P): Preliminary values subject to further review. Please note that the wave effects, which are a key component of coastal flood elevations, are not included in the SWEL and must be calculated separately. Time. Tide height (m) Sunday, Dec 13 Wind. Two critical processes related to sediment transport in the lake are (1) the resuspension of sediments due to wind-generated storm waves and (2) the movement of resuspended material by lake currents during storm wind events.
