Purpose of Hydrodynamic Modeling

• Provide currents to Ship Simulator

• Evaluate changes to circulation/salinitydue to channel modifications


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

• Criteria

Represent Channel Mods

Local Mass Conservation


Model Selection

• Model TypesStructured 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

Structured Grids

Unstructured Grids

UnTrim (Casulli & Walters 2000)

• Unstructured grid

• Mass Conservation

• Stability independent of surface wave speed

• Degenerate to 2D & 1D

• Flooding & Drying

• Proprietary

MIKE FM/FV (DHI)

• MIKE Zero

• (Sediment Transport)

• (Water Quality)

• (Ecolab)

• Stability dep. Surface wave speed

• Proprietary

ELCIRC (Oregon Grad Institute 2001)

• Open Source

Alternatives

• Six preliminary plans

• 2 to 6 alternatives for each


Preliminary Alternative Plans

Orchid Orchid Daisy Daisy

Zinnia Zinnia Violet Violet Iris Iris

Rose Rose


Scope of Modeling

• Model SimulationsCalibration & Verification (existing data)Existing Conditions – Base year w/o project (future w/o ?)Three Alternative Project Plans

• Time Scales Project Alternative Optimization – 30 daysImpacts to Circulation & Salinity – Seasonal (3-4 months)


Revised Scope• OLD

A re-evaluation of the entire harbor projectFeasibility-level study

• NEWMain ship channel congestion relief measures - Anchorage areas - Loop channel - Non-structural alternatives

Other Tasks

• 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

• 1 April 04 - Alternatives (~ 3 model simulations)

• 1 Jun 04 - Recommended Plan, Locally Preferred Plan


Vessel Calls & Cargo TypeTampa Distribution of Calls by Vessel & Cargo Type CY 2001

VESSELL TYPE CARGO TYPE % OF CALLS

Cruise Ships Passengers 6%

General Cargo ShipsBreak Bulk, Neo-bulk,

Containerized 18%

Bulk Carriers & Barges Dry Bulk

Tankers & Barges Petroleum Products

29%

47%

Environmental ResourcesDiverse, high quality fish & wildlife resources within Tampa Bay

• Bethnic Resources

• Estuarine 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)

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
