Effect of conduit/fracture geometry and porous matrix properties on predicting the sources, fluxes, travel paths and travel times of water and solutes to Silver Springs |

Physics-based distributed models for simulating flow and solute transport in karst aquifers are generally based on the discrete-continuum approach in which flow in the three-dimensional porous limestone matrix is coupled with flow in discrete one-dimensional conduits. In general, however, little is known about the geometry of conduit networks. To quantify and analyze the reliability of discrete-continuum models it is important to explore flow and transport behavior over an ensemble of possible karst conduit networks within a stochastic framework. In this project we generate representative realizations of conduits and fractures that honor what is known about the geology, geomorphology and hydrogeology of Silver Springshed and incorporate them into a local-scale Silver Springshed equivalent porous media model. Monte Carlo simulation is used to systematically explore the relative importance of conduit/fracture geometry and porous matrix properties on predicting the sources, fluxes, travel paths and travel times of water and solutes to Silver Springs. |
