11. Applications to environmental monitoring 2. Much of the drainage occurs in the subsurface 3. Altered drainage can increase dissolution of the underlying geology 1. Alteration of the landscape impacts drainage Ocala Karst after overburden removal Peace River draining underground Winter Park sinkhole, leaky pool drain

12. Applications to environmental monitoring 1. Alteration of the landscape impacts drainage 2. Much of the drainage occurs in the subsurface 3. Altered drainage can increase dissolution of the underlying geology 4. Subsurface dissolution pathways can be detected using seismic profiling, and ground- truth using invasive methods
