  2. Freshwater Flows Into Northeastern Florida Bayand Flow Exchange in Florida Bay Channels

  3. OBJECTIVES • Collect continuous stage, velocity and salinity data at major creeks flowing into northeastern Florida Bay • Compute discharge at creeks and study the quantity, timing and distribution of that flow

  4. Why is Flow-Salinity-Water level Information Needed? Accurate flow information is needed to help understand the circulation, mixing, and salinity dynamics of Florida Bay and the Everglades Quantify nutrient, sediment, and biological fluxes Flow, stage, and salinity data help verify inland simulations of marsh-flow dynamics Evaluate performance of management practices

  5. Overview • Study area • Monitoring station descriptions • Quantity, Timing and Distribution • Methods of acoustic flow measurements • Data from creek monitoring sites • Flow characteristics • CERP/GEER Integration • Collaboration/Data users • Florida Bay Flow Exchange- • Pink Shrimp Studies

  6. Study Area

  7. Monitoring Sites and Structures ~ 5 miles S332 TSB S175 S18C S197

  8. Western Extent of Study Area Upstream Taylor East Creek Taylor River McCormickCreek ~ 1.5 miles

  9. Taylor River Study Area Upstream Taylor ~ 0.5 miles Buttonwood embankment Little Madeira Bay Taylor River

  10. ~0.5 miles Central Extent of Study Area JB5C Stillwater Creek JB2E Joe Bay JB1E JB8W Trout Creek Mud Creek

  11. Eastern Extent of Study Area East Highway Creek Oregon Creek West Highway Creek Stillwater Creek ~ 1.5 miles

  12. Quantity of Flow is Measured Using Acoustic Doppler Techniques Side Looking Doppler Acoustic Doppler Current Profiler (ADCP)

  13. ~0.5 miles Flow Exchange Between Joe Bay and Long Sound Joe Bay Snag Bay Long Sound Florida Bay

  14. Timing of Flow • Seasonal trends • Storm events

  15. Seasonal Timing of Flow Showing Brackish to Fresh Transition at Taylor River

  16. Stage at Trout Creek During Storm Events

  17. Discharge at Trout Creek During Hurricane Irene

  18. Salinity at Trout Creek During Hurricane Irene

  19. CERP INTEGRATION • The principal goal of restoration • “ to deliver the right amount of water, of the right quality, to the right places, and at the right time.”

  20. Associated Projects • NSF funded LTER at FIU • CERP C-111 Spreader Canal

  21. C-111 SPREADER CANAL PROJECT

  22. Monitoring Flow, Stage, and Salinity in Florida Bay Channels

  23. OBJECTIVES • Collect continuous stage, velocity and salinity data at six major channels in Florida Bay • Compute discharge within the channels and study the quantity, timing and distribution of that flow • Help quantify postlarval Pink Shrimp movement into and out of Florida Bay
