Freshwater Flows Into Northeastern Florida Bay
and Flow Exchange in Florida Bay Channels
![Page 3: Please note: this presentation has not received Director’s approval and is subject to revision](https://reader035.vdocument.in/reader035/viewer/2022062500/56815007550346895dbddcca/html5/thumbnails/3.jpg)
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
![Page 4: Please note: this presentation has not received Director’s approval and is subject to revision](https://reader035.vdocument.in/reader035/viewer/2022062500/56815007550346895dbddcca/html5/thumbnails/4.jpg)
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

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
