Modeling Aquifer Inhomogeneities with Analytic Elements with Application in a Model of Flow at the St. Croix Rest Area Storm Runoff Pond

摘要

The design for Interstate Highway 94, east of St. Paul, Minnesota included a dead-end storm water retention pond constructed by the Minnesota Department of Transportation (Mn/DOT), for the purpose of collecting highway runoff. Flow into the pond will discharge primarily through the pond bottom into the groundwater system. Concern for potential impacts to both local and regional groundwater levels prompted Mn/DOT to conduct a groundwater study using an analytical element computer model. Presented in the report is a summary of the analytical aquifer modeling method, including basic theory, fundamental equations, and a brief description of how to access the computer program.
