Patrick Kelly 1 1 University of Miami, Coral Gables, FL Introduction The Florida Everglades is an interwoven mesh of several distinctly unique ecosystems that have varying requirements for survival. However, one overwhelming similarity between these ecosystems is the substantial need for an abundance of free-flowing freshwater. Since as early as the 19 th century, with the onset of significant urban sprawl and several re- routing and reclamation projects, the natural flow of freshwater south from Lake Okeechobee has been significantly disrupted, adversely affecting each subsystem, not to mention countless species of birds and other wildlife. Additionally, with the implementation of land reclamation projects for agricultural and developmental use and subsequent “drainage” of the area, the Everglades has experienced a diminished capacity for freshwater recharge. Recently, the first significant efforts to restore the Everglades have been undertaken. Much of these efforts revolved around the need to restore the naturally “sheet- like”, widespread, meandering flow into the area. Several alternatives have been explored, such as the removal of dozens of miles of canals and the elimination of several flow impedances. Of note is the debate surrounding the alternatives for Tamiami Trail (US-41), which has been identified as a major flow barrier. The following is a brief introduction to the investigation of the effects of spreader swale installation with the intent of restoring sheet flow to the Everglades National Park at two specific culvert locations along Tamiami Trail. Monitoring Methods •Four specific culvert locations along Tamiami Trail monitored (Two for pilot swales, two control sites) See Figure 3 •Measurements taken of flow through culverts and water elevation at various wells •Automatic flow measurements taken in center barrel of culvert using Sontek Argonaut SW for shallow flow. See Figure 1
