Characterization of Sandhill Lake Soils: In Support of St. Johns River Water Management District's Minimum Flows and Levels Program. Special Publication SJ2007-SP7

摘要

The goals of this study were to quantify the CFH and HAC in soil samples collected near the FH and FL LSIs at three sandhill lakes and develop models to estimate the CFH and HAC from the physical soil characteristics. In addition to these goals, the CFH and HAC were related to the AEVs, models to estimate the AEVs from the physical soil characteristics were developed, and an example of how this research might be applied to support the determination of minimum levels is presented. The physical soil characteristics were determined and compared among lakes to accomplish these goals. The measured and calculated soil characteristics are summarized in Appendix B (Table B1 and B2) and were compared with the CFHs, AEVs, and HACs. Multiple linear regressions were developed to predict the CFH, AEV, and HAC from the physical soil characteristics to quantify offsets to support the determination of minimum levels at sandhill lakes. Linear regressions were also developed between the CFH and HAC and the AEVs in an attempt to provide an alternative method to predict the CFH and HAC.
