"The Civil and Coastal Engineering Department at the University of Florida was retained by the St. Johns River Water Management District (SJRWMD) to evaluate the dynamic hydraulic response of a karst aquifer in north-central Florida using innovative analyses and quantitative tools. This project was motivated by the need of the SJRWMD to manage water resource caution areas (i.e., areas where existing or future anticipated water resources are deemed insufficient to satisfy current or projected demands over a 20-year planning period) (St. Johns River Water Management District, 2005a, b; Kinser et al., 2006). The area of interest is the springshed that provides for Blue Spring in Volusia County in northeast Florida. The University of Florida retained Southwest Research Institute® in this investigative endeavor. The critical components of the assessment include an evaluation to determine whether MODFLOW-DCM Version 2.0 (Painter et al., 2007) improves existing models, whether the improvements adequately capture the hydraulic dynamics of the karst groundwater flow system, and whether these are useful in groundwater resource management. MODFLOW-DCM is an innovative numerical simulator designed to account for the dynamic interaction between diffuse and conduit flow inherent in karst aquifers. This evaluation also determined whether MODFLOW-DCM could simulate the hydraulic response of a karst aquifer in which conduits are poorly located and characterized."--Introduction.
