## Freshwater Flows Into Northeastern Florida Bayand Flow Exchange in Florida Bay Channels

## 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

## 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

## 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.”

## Associated Projects

- NSF funded LTER at FIU
- CERP C-111 Spreader Canal

## 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
