Hydrodynamics of the Southwest Coast Estuaries
Principal Investigators: Eduardo Patino, Lars Soderqvist, and Victor Levesque

|
This study is a part of the U.S. Geological Survey South Florida Ecosystems Initiative and Place Based Systems programs.
The study provides information about the hydrodynamics of estuarine rivers along the southwest coast of Everglades National Park.
The river discharges reaching the estuaries on the southwest coast are an important consideration facing resource management of the Everglades. |

| Water Year median residual discharge values for stations. |
| Discharge stations are equiped with velocity, water level, temperature, and salinity sensors.
Data is collected every 15 minutes.
Velocity ratings are developed for each station using discharge measurements and station instrument data. |

| Instantaneous discharge for each 15 minute interval is calculated for each station (blue line in figure below).
Instantaneous discharge is filtered using a low-pass filter to remove semi-diurnal tidal frequencies.
The residual discharge data reveal responses to meteorological and long-term tidal forcing (red line in figure below). |

| Mean and median discharge for calendar years (January - December) or water years (October - September) can help determine effects of upgradient water delivery modifications.
Annual mean and median discharges are remarkably similar in magnitude.
Annual mean discharges for 1998 are the lowest for the period of record, while annual mean discharges for 1999 are the highest for the period of record. |
