Modeling Approach

• ADCIRC - Water-Levels and Circulation
• WIS - Wave Hindcast
• STWAVE - Wave Transformation
• GENESIS - Shoreline Change/Transport
• SMS - Surface Modeling System

Why use a GIS?

• Develop a sediment budget for the region
• Facilitate the sharing of data
• Decision Making Tool
• Institutional knowledge
