John D. Jastram, Carl E. Zipper, Lucian W. Zelanzny, Kenneth Hyer
2010, Journal of Environmental Quality (39) 1306-1316
Turbidity is an effective tool for estimating and monitoring suspended sediments in aquatic systems. Turbidity can be measured in situ remotely and at fine temporal scales as a surrogate for suspended sediment concentration (SSC), providing opportunity for a more complete record of SSC than is possible with physical sampling approaches....

James A. Falcone, Daren M. Carlisle, David M. Wolock, Michael R. Meador
2010, Ecology (91) 621-621
Stream flow is a controlling element in the ecology of rivers and streams. Knowledge of the natural flow regime facilitates the assessment of whether specific hydrologic attributes have been altered by humans in a particular stream and the establishment of specific goals for stream-flow restoration. Because most streams are ungaged...

Hydrologic conditions in the Florida Panther National Wildlife Refuge, 2006-2007
Ronald S. Reese
2010, Open-File Report 2010-1270
Much of the surface water that flows into the Florida Panther National Wildlife Refuge (FPNWR) probably exits southward through Fakahatchee Strand as it did prior to development, because culverts and bridges constructed along I-75 allow overland flow to continue southward within the strand. During the dry season and periods of...
