Objective l.jpg


  • To analyze water depths in the Florida Everglades, relating the water levels to the hydrologic needs of the American Alligator.

    "The Everglades ecosystem must be restored both in terms of water quality and water quantity and must be preserved and protected in a manner that is long term and comprehensive.“

    ~ The Everglades Forever Act (Florida Statute No. 373.4922)

Everglades geography l.jpg

Everglades Geography

  • South Florida

  • Kissimmee Watershed

  • Lake Okeechobee

  • 100 Miles

  • Florida Bay

Facts on the everglades l.jpg

Facts on The Everglades

  • 10, 000 Islands

  • 6 Inches Beneath Sea Level

The american alligator l.jpg

The American Alligator

  • Largest Reptile in North America

  • Length 8 – 14 Feet

  • 35 Eggs, 15 Hatch, 6 Live to a Year, 4 Mature

  • Populate North Carolina to Texas

  • Thermoregulate

    • Ectothermic

    • Active at Ambient Temperature of 82° F to 92° F

    • Dormant at Ambient Temperature of 55° F

Adequate water depth and the alligator l.jpg

Adequate Water Depth and the Alligator

  • Thermoregulation

    • Internal Body Temperature of 86° F to 88° F

    • Water Temperature of81° F to 88° F

    • Deep Enough for Total Submergence (~ 18 inches)

    • Deep Enough for Cool Temperature

  • Escape from Danger

  • Nest Protection

Research plan l.jpg

Research Plan

  • Enter Water Levels at Specific Gauge Station Locations

  • Build Elevation Model for Everglades Area

  • View Temporal Data using the Tracking Analyst

  • Perform Raster Calculation with Water Levels and Elevation Values to find Water Depth (Interpolate to Raster)

  • Analyze Water Depths, Relating to Hydrologic Requirements of the American Alligator
