  1. Test of CCHE2D-CoastA 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 Hurricane Tide

  3. Surface Wind by Holland’s Hurricane Model

  4. Air Pressure at t = 36h

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

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

  7. r A Hurricane Model (Holland 1980) Hurricane Pressure Field VH Surface Wind Velocity Resultant Wind Speed VW Wind Stress Pc=central pressure; P∞=ambient pressure; ρa=air density R=Radius of maximum wind;Cd = drag coefficient
