Introduction

• Real-time Ocean Wave Modeling System
• Data Sources Buoys, bathymetry (depth) maps
• Output near-shore costal wave heights

Why do we care?

• Recreational
• Surfing
• Swimming
• Boating
• Kayaking
• Sailing

• Safety
• Lifeguards
• Residential
• Storm Surge
• Scientific
• Historical Significance/ Statistics
• Mathematical Model

Previous Work

• Costal Data Information Program
• Scripps, UCSD, US Army Corp of Engineers
• Fairly realistic Real-Time deep water surface
  wave conditions for the California coast
• Unrealistic near-shore wave modeling
• Ref-Diff
• More Realistic near-shore data
• Not Yet Real-Time

What are WE doing?

• Using Existing wave model Engine (Ref-Dif)
• Leaving complex mathematical modeling engine to
  those who know it best
• Expanding for Real-time
• Updates when buoys update
• Making the existing system more general
• Database Engine for data collection
• Easily adaptable to different area maps

• Storage
• mySQL
• Mathematical Model
• Ref/dif system
• Output
• Height Map
