Raymond W. Schaffranek (retired) 2005 maps and data http://sofia.usgs.gov/exchange/schaffranek/schafQW.html Five basic water-quality parameters (temperature, pH, specific conductance, dissolved oxygen, and salinity) were collected at each site having sufficient depth A complex network of canals, levees, and control structures, designed to control flooding and provide a continuous supply of fresh water for household and agricultural use, has altered naturally occurring flow patterns through the Everglades and into Florida Bay. Quantification of dynamic flow conditions within the south Florida ecosystem is vital to assessing implications of the residence time of water, potentially nutrient-enriched (with nitrates or phosphates) or contaminant-laden (with metals or pesticides), that can alter plant life and affect biological communities. Improved numerical techniques are needed not only to more accurately evaluate discrete forces governing flow in the canals and wetlands but also to analyze their complex interaction in order to facilitate coupled representation of transport processes. Flow and transport processes are integrally linked meaning that precise quantification of the fluid dynamics is required to accurately evaluate the transport of waterborne constituents. Robust models that employ highly accurate numerical methods to invoke coupled solution of the most appropriately formulated and representative equations governing flow and transport processes are needed. Through strategic use of a model, cause-and-effect relations between discharge sources, flow magnitudes, transport processes, and changes in vegetation and biota can be systematically investigated. The effects of driving forces on nutrient cycling and contaminant transport can then be quantified, evaluated, and more effectively factored into the development of remedial management plans. A well-developed model can be used to evaluate newly devised plans to improve freshwater deliveries to Florida Bay prior to implementation. This project ended in 1999.

Locations for the 1999 sites are in UTM coordinates Parameters recorded for sites in 1997 include temperature, salinity, conductivity, dissolved oxygen and pH. In 1999 water depth, temperature, salinity and conductivity were recorded. Water Quality data Collection Collection of flow data in the canal C-111 overbank and adjacent wetland area began in September 1997 near the conclusion of the spoil removal efforts. Data were collected along 9 to 12 transect lines covering the 7.1-km segment of C-111 beginning 1.1 km north of US Hwy 1 bridge and ending 2 km south of S-18C. Transects originate at locations on the southwest bank of the canal opposite culverts under the levee road on the northeast bank and extend normal to the canal approximately 1.5 km into the adjacent wetlands. Transects lines are numbered 1 through 9 beginning with the culvert nearest US Hwy 1 bridge. Measurement sites are spaced at variable-length intervals along the transect lines. Five basic water-quality parameters (temperature, pH, specific conductance, dissolved oxygen, and salinity) were collected at each site having sufficient depth using a Hydrolab multi-parameter sensor positioned at mid-depth.
