Incorporating uncertainty into high-resolution groundwater supply models

Groundwater modeling is a useful tool for evaluating whether an acquifer system is capable of supporting groundwater withdrawals over long periods of time and what effect, if any, such activity will have on the regional flow dynamics as well as on specific public water, agricultural and industrial supplies. An overview is given of an ongoing groundwater modeling study of the Chicot Aquifer in southwestern Louisiana where a low-resolution groundwater model is being used to study the regional flow in the Chicot acquifer and to provide boundary conditions for higher-resolution inset models created using telescopic mesh refinement (TMR).
