Integrated Physical and Chemical Observations of Water-rock Interactions and Coupled Matrix-conduit Flow in the Karstic Floridan Aquifer
Goals and Objectives
 
The flow field of karst aqufiers includes conduits, fractures, and intergranulare porosity of the matrix rocks. Full characterization of flow and chemical reactions in karst aqufiers requires understanding flow through each of these components. This project addresses questions of coupling between aquifer components and water sources by integrating new chemical measurements with previous observations of flow through the Floridan aquifer.
