A GIS-based hydrologic restoration analysis for the Northern Indian River Lagoon watershed [electronic resource] /
Abstract (Summary)ABSTRACT: Several factors have changed the quantity and quality of waters discharging to the Indian River Lagoon (IRL) including extensive drainage alterations, impoundment of salt marshes, and point and non-point sources of pollution. The Nature Conservancy (TNC) created a two-phase GIS-based project with the purpose of identifying target areas for acquisition or conservation easements that address the water quality, water quantity, and conservation issues in the area. Phase two of the project, the focus of this research, includes splitting the IRL watershed into characteristically similar zones and performing a comprehensive geographic information systems (GIS) analysis for each. The central and southern zones analysis identifies and ranks restorable freshwater wetlands (RFW) in the historic flatwood region west of the historic watershed boundary. This analysis applies a weighted average approach using GIS attribute tables to rank and weight the RFW based on 4 categories: water quality benefits, water quantity benefits, conservation value, and ease of restoration.
