  1. Emergency Management Mission: To prepare for and respond to disasters and emergencies Prevent or minimize loss of life and damage to property

  2. Functional Needs and Requirements: Degree of storm surge flooding coincident with the arrival of a hurricane around the Hawaiian coastline.

  3. Evacuation

  4. The Problem: The cumulative hurricane surge must include: • The combined effects of the earth’s rotation. • The changing atmospheric pressures. • The ocean surface/wind coupling. • The bottom frictional effects.

  5. How do we Model? Numerical schemes: • Quasi-one dimensional • Two dimensional • Three-dimensional

  6. Not an Easy Task: • Storm intensity, size, path, duration over water. • Atmospheric pressure variation. • Speed of translation. • Bathymetry of the offshore region. • Astronomical tides. • Initial water rise, surface waves, and associated wave setup and run up due to wind frictional effects.

  7. Other Models • ADCIRC Coastal Circulation and Storm Surge Model • NOAAA’s Vertical Datum Transformation (VDatum) Tool • NOAA WAVEWATCH III • Coastal Field Data Collection - CFDC • Special Program to List Amplitudes of Surges from Hurricanes—SPLASH • FEMA TTSURGE model • SLOSH – Sea, Lake, and Overland Surges from Hurricanes • MIKE 21 – 2D Modeling System for Floodplains •  Storm surge modeling system (SSMS) and Curvilinear-grid Hydrodynamics in 3D (CH3D)-SSMS

  8. What we Expect

  9. Keep it Simple

  10. Emergency Management Mission: To prepare for and respond to disasters and emergencies Prevent or minimize loss of life and damage to property
