Near Valdosta, Georgia, for example, the Withlacoochee River loses as much as 100 cfs to a sinkhole area.
Calibration accounts for the difference between a circular conduit and a non-circular one.
We showed that a complex network of conduits taking water from a surface stream can be replaced by a single equivalent conduit as long as the network has only one input and one output. If this stipulation is untrue, a more complicated two-port network may be used. We developed the CLG model in Visual Basic that can easily be converted to Fortran or any other language. Observations of plugging in Saturday Cave point to the importance of debris to the morphology of a karst aquifer. We also developed a model of flow in Saturday Cave that showed good agreement with observations.
