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
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
Model Selection
Tampa Harbor Project General Re-evaluation Study
• Criteria
• Model Types
Structured Grid
Represent Channel Mods
Local Mass Conservation
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

Unstructured Grids
UnTrim (Casulli & Walters 2000)
MIKE FM/FV (DHI)
• Unstructured grid
• MIKE Zero
• Mass Conservation
• (Sediment Transport)
• Stability independent of
surface wave speed
• (Water Quality)
• Degenerate to 2D & 1D
• (Ecolab)
• Flooding & Drying
• Stability dep. Surface wave

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

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)
• OLD
Revised Scope
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
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

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
