Presentation Transcript

  1. Tidal Constituent and Residual InterpolationSurvey Planning and Weighting Function Computation

  2. Clarendon Fort Pulaski

  3. Save as “Shoreline”

  4. TCARI Lat1 Lat2 –Lon1 –Lon2 Results (36) in file Lat1 Lat2 –Lon1 –Lon2 (Saved on every ones C:\TCARI) Stations with Accepted Datums and Either Working or Accepted Harmonic Constituents in DMS Excel

  5. Station Identification Station Datums Station Harmonic Constituents

  6. Data Inventory Harmonic Analysis (29d or 365d) Store Constituents Store Constituents Retrieve Local Results

  7. Loading and Cleaning Shoreline • Load Shoreline. • Close off all open shoreline • Create ocean boundary • Find bad segments • Jump to bad segments to • clean each one. Bad shoreline point Create ocean boundary Close all open segments Clean Shoreline (Find Bad Segments)

  8. Create Triangulated Mesh Some stations fall outside of the shore- line. You can move then inside the shore- line by adjusting the lat/lon. If they are not inside, they will not get used. Triangulated Mesh

  9. 1500m Clarendon station radius increased to 3500m

  10. Weights for Skull Creek 8669133 1500m 100% 80% 70% 60% 50% 40% 8669133 30% 10% 0%

  11. Interpolated datum offsets

  12. Weighting Percentages for harmonic constituents

  13. Weighting percentages for residuals Fort Pulaski Weighting percentages for residuals Clarendon

  14. If Clarendon were to drop out, can you just use Fort Pulaski? Differences up to ~0.4m

  15. Error Estimation Fort Pulaski and Clarendon Analysis shows that Clarendon needs to be operating during the time of the survey.

  16. Tide Station Info Two stations are in and operating. The rest are all historic stations that can be used for harmonics and datums Only check “Solve Combinations” if your analysis shows that it is acceptable for an operating gauge to drop out.

  17. Spot Checking for Final Analysis Comparing TCARI results against our Traditional discrete zoning • Load verified 6-minute water level data into TCARI • Review WL Graphs (Show water level graphs) 3. Choose a spot in the grid, a landmark, buoy, or other feature. Show Tide Corrector

  18. Comparing TCARI results with zoning at that spot

  19. TCARI Project Instructions TCARI Field SOP Delivered with every set of Project Instructions
