1 Test of CCHE2D-Coast A Hypothetical Hurricane in the Mississippi/Louisiana Gulf Coast Yan Ding NCCHE, University of Mississippi, 6/4/2011

2 Computational Conditions for Modeling Storm-Surge Tide Hypothetical Hurricane: Central Pressure = 970 mbar, Max. Radius = 50km, Moving speed = 25km/h, Direction = from SE to NW Tide: M2, Tidal Amplitude = 0.2m Tide Hurricane

3 Surface Wind by Holland’s Hurricane Model

4 Air Pressure at t = 36h

5 Storm Surge Height and Wind t = 36ht = 38h

6 Storm Surge Height and Current t = 36ht = 38h

7 A Hurricane Model (Holland 1980) r Hurricane Pressure Field Surface Wind Velocity Resultant Wind Speed Wind Stress Pc=central pressure; P∞=ambient pressure; ρ a =air density R=Radius of maximum wind; C d = drag coefficient VHVH VWVW
