17 Beach response to waves varies greatly throughout the SCBPS region. specific How a specific beach responds to waves can be surprisingly well predicted by simple models detailed “tuned” with detailed monitoring data. Numerous wave-driven subcells exist within the Oceanside littoral cell. 6 Years of Concurrent Wave & Sand Monitoring Preliminary Findings 17

23 CDIP Waves and Sand MOnitoring & 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” 23

24 The CA coastline is divided into a contiguous set of MOP Polygons. Polygon IDentifier based on County 24

25 Each MOP Polygon is bisected by a MOP Transect. 25

26 Each MOP Transect is bounded by a MOP Nearshore Site and a MOP Backbeach Site. Backbeach Site ~100m alongshore spacing Nearshore Site (10m Depth) 26

27 Online Access To MOP Wave Information 27

28 CA Counties with Operational MOP Wave Information 28

29 Predicted surfzone averaged alongshore currents are provided at each 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 29

30 MOP Coastal Inundation Predicted Inundation Elevations will be provided for transects with simple shoreline profiles Known elevation that results in parking lot flooding at this location 30

32 Each MOP Polygon will contain a set of MOP Sandboxes. NEXT: MOPS & RSM 32
