Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains lines representing the major groundwater divides in the Floridan aquifer system. The position of the divides was modified from Bush and Johnson, 1988, using the average Upper Floridan... Categories: pre-SM502.8; Tags: 1988, 2010, Alabama, Bush, Florida, All tags...
