Florida Water & Ecosystems

Why can freshwater releases upstream change conditions in Florida estuaries?

• Estuaries receive only rain directly
• They alter salinity and the freshwater-saltwater balance
• Freshwater cannot mix with seawater
• Salinity depends only on the age of a port

What explains why two maps assign different lengths to Florida’s coastline?

• Only changes in population density
• Different spatial resolution and treatment of inlets and island shores
• One map measured climate instead of shorelines
• Florida’s coastline has a single resolution-independent measurement

Why can changes in the Kissimmee basin affect South Florida wetlands?

• Lake Okeechobee has no hydrologic connections
• All watersheds stop at county boundaries
• The Kissimmee system drains only to Alaska
• Water pathways connect the basin, Lake Okeechobee and downstream Everglades

Which ecological variable measures how long a wetland remains inundated?

• Hydroperiod
• Latitude
• Nominal GDP
• Port throughput

What combination may intensify coastal aquifer saltwater intrusion in Florida?

• Sea-level rise and reduced freshwater hydraulic head
• Elimination of all groundwater gradients
• Higher mountain snowpack in Florida
• Lower sea levels and increased freshwater recharge alone

Why can Floridan aquifer policy require regional coordination beyond state borders?

• Groundwater never crosses political borders
• It supplies only Tallahassee city hall
• The aquifer system extends into other southeastern states
• Aquifer limits exactly match county maps

How should sinkhole susceptibility be assessed in Florida?

• Use only distance to Orlando’s theme parks
• Assign identical hazard to every Florida property
• With site-specific geology, groundwater and subsurface conditions
• Infer risk solely from state GDP

Why should coastal erosion models differ across Florida settings?

• Every coastline has identical sediments and waves
• Barrier islands and mangrove estuaries have different structures and processes
• A single seawall design works everywhere
• Only inland rivers experience erosion

What spatial unit best captures the connected Everglades water system?

• The watershed basin across jurisdictions
• Only Miami city limits
• Only the Everglades National Park fence
• Only one drainage canal

Which variables matter in assessing the success of Everglades water restoration?

• Only annual rainfall total
• Where, when and how much water moves, plus water quality
• Only the number of visitors to a park
• Only the count of road intersections
