  1. Tampa Harbor Project General Re-evaluation Study Presented by: US Army Corps of Engineers Jacksonville DistrictDecember 11, 2003 Hydrodynamic Modeling

  2. Introduction Tampa Harbor Project General Re-evaluation Study • USACE South Atlantic Division • Directed Jacksonville District to seek • support for modeling tools & procedures • from • Sponsors • Tampa Port Authority, City of St. Pete • Other stakeholders • ABM, TBEP, USGS

  3. Outline Tampa Harbor Project General Re-evaluation Study • Introduction • Purpose for Hydrodynamic Modeling • Model Selection • Alternatives • Scope of Modeling • Other Tasks

  4. Introduction Tampa Harbor Project General Re-evaluation Study • Navigation Projects • Tampa Harbor GRS • St Petersburg GRS • Previous Corps Funded Hydro Model • Circulation Changes due to Dredge & Fill (Goodwin, ’87,’91)

  6. Purpose of Hydrodynamic Modeling Tampa Harbor Project General Re-evaluation Study • Provide currents to Ship Simulator • Evaluate changes to circulation/salinity • due to channel modifications

  7. Existing Conditions • Strong wind, current and tide considerations • 43-foot deep main Federal channel by 500-foot wide (Cut A-F) • Increased vessel sizes and port calls • Vessel accident history from 1980 resulting in loss of life, navigation delays & environmental damage • Tampa Bay Safety Guidelines Committee established • Vessel Handling Guidelines for Movement established • Commerce light-loaded, traffic flow impeded, navigation delays • Tampa Harbor Safety Zones established • Tampa Harbor Security Zones established

  8. Model Selection Tampa Harbor Project General Re-evaluation Study • Criteria • Represent Channel Mods • Local Mass Conservation • Model Types • Structured Grid • Orthogonal – ECOM, EFDC • Boundary Fitted – CH3D • Nested – Mike2/3 • Unstructured Grid • Finite Element – ADCIRC, RMA, MIKE FM • Finite Volume – UnTrim, ELCIRC, FVCOM MIKE FM, Delft

  9. Structured Grids

  10. Structured Grids

  11. Unstructured Grids

  12. MIKE FM/FV(DHI) UnTrim(Casulli & Walters 2000) • Unstructured grid • Mass Conservation • Stability independent of surface wave speed • Degenerate to 2D & 1D • Flooding & Drying • Proprietary • MIKE Zero • (Sediment Transport) • (Water Quality) • (Ecolab) • Stability dep. Surface wave speed • Proprietary ELCIRC(Oregon Grad Institute 2001) • Open Source

  13. Alternatives Tampa Harbor Project General Re-evaluation Study • Six preliminary plans • 2 to 6 alternatives for each

  14. Preliminary Alternative Plans Daisy Orchid Rose Zinnia Violet Iris Tampa Harbor Project General Re-evaluation Study

  15. Scope of Modeling Tampa Harbor Project General Re-evaluation Study • Model Simulations • Calibration & Verification (existing data) • Existing Conditions – Base year w/o project (future w/o ?) • Three Alternative Project Plans • Time Scales • Project Alternative Optimization – 30 days • Impacts to Circulation & Salinity – Seasonal (3-4 months)

  16. Revised Scope • OLD • A re-evaluation of the entire harbor project • Feasibility-level study • NEW • Main ship channel congestion relief measures • - Anchorage areas • - Loop channel • - Non-structural alternatives

  17. Other Tasks Tampa Harbor Project General Re-evaluation Study • Ship Simulator - optimize channel design • Channel Shoaling- Diagnostic Modeling System • PORTSIM- queuing model/ economic analysis • Ship Wake Analysis - potential impact on seagrass • Harbor Oscillation – limited to local areas

  19. Project Schedule Tampa Harbor Project General Re-evaluation Study • 1 Mar 04 - Tampa & St Pete • Calibration / Verification • Existing Condition • 1 April 04 - Alternatives (~ 3 model simulations) • 1 Jun 04 - Recommended Plan, Locally Preferred Plan

  20. Vessel Calls & Cargo Type Tampa Distribution of Calls by Vessel & Cargo Type CY 2001 VESSELL TYPE CARGO TYPE % OF CALLS Cruise Ships Passengers 6% Break Bulk, Neo-bulk, Containerized General Cargo Ships 18% Bulk Carriers & Barges Dry Bulk 29% Tankers & Barges Petroleum Products 47%

  21. Environmental Resources Diverse, high quality fish & wildlife resources within Tampa Bay • Bethnic Resources • Seagrass - beds extensive; high value fisheries nursery • Soft bottom – sand/muck (80%) • Hardbottom – invertebrate & fish habitat (850 acres) • West Indian Manatee – extensive protection zones (FWS, DEP, FWC) • Estuarine Resources • Marshes & mangroves – fisheries habitat • Mud flats & salt barrens – microscopic organisms fuel for Bay productivity • Associated uplands – foraging, nesting, loafing habitat (bald eagle, osprey, wood storks) • Low salinity habitats – oysters thrive “Charting the Course,” CCMP for Tampa Bay, December 1996

  22. Study Guidance • ER 1105-2-100 - “Revised Planning Guidance Notebook” • ER 1165-2-1 - “Digest of Water Resources Policies & Authorities” • EM 1110-2-1613 - “Navigation Design Safety Component” • ER 1165-2-131 – “Over Depth Dredging” • EC 1165-2-203 – “Internal Technical Reviews” • USCG 33 CFR 165 – “Security Zones” • Port of Tampa Authority Input • Tampa Harbor Pilot Association Input

  23. Vessel Tonnage & Movement CY 2001 Tampa Area Ports’ Tonnage and Vessel Movements * CY 2001 INBOUND & OUTBOUND TRIPS TAMPA AREA PORTS CY 2001 SHORT TONS Tampa 45,793,544 6,930 Port Manatee 3,801,621 654 Weedon Island 1,038,674 124 St. Petersburg 52,000 852 Total 50,685,839 8,560 * WBC of the U.S., CY 2001, Part 2 – Waterways and Harbors, Gulf Coast, Mississippi River System and Antilles
