2. SIO Waves and Beaches Model Prediction (MOP) System Wave Monitoring  Wave Buoy Network  NOAA WW3 Forecasts Surfzone Monitoring  Current Measurements  Dye/Drifter Tracking  Jetski Sand level Surveys Beach Modeling  Beach width change  Inundation levels Coastal Wave Modeling  Breaking wave heights  Radiation stresses (Sxx,Sxy) Beach Monitoring  LIDAR  ATV Sand level surveys Surfzone Modeling  Current Direction & Speed  Bottom Velocities Public Access To Core Coastal Environment Variables Via “MOP Sites”

3. Alongcoast Model Prediction “MOP” Sites - 10m water depth. - 100m alongshore spacing.

4. CA Counties with Operational MOP Wave Information

5. Each MOP Site also has an associated cross-shore MOP Transect and MOP Polygon.

6. Predicted surfzone averaged alongshore currents will be provided for each MOP transect on a relatively straight beach without obstructions. A seasonal cross-shore bathymetry profile is assumed if there is no recent survey data. MOP Alongshore Currents

7. MOP Site Inundation Predicted Inundation Elevations will be provided for transects with simple shoreline profiles Known elevation that results in parking lot flooding at this location

8. Each MOP Polygon contains a set of MOP Sandboxes.

9. Torrey Pines (MOP SD0584) Beach Width Change Width Change (m) Date model measured MOP Beach Width Change A data-adaptive cross-shore radiation stress (Sxx) model will provide beach change predictions for MOP Polygons with sufficient beach survey information.
