Abstract: The Metro Model is a regional ground water flow model encompassing the Twin Cities seven-county Metropolitan area. The Metro Model provides the regional flow conditions that serve as the starting point for site-specific models that can be constructed through modification and addition of local detail. The computer model simulates multi-aquifer groundwater flow and is based on a conceptual model that consists of five aquifer layers, four of which represent bedrock units, and one representing a glacial drift aquifer. The Metro Model is actually composed of four separate models. One model simulates flow in Layers 4 and 5 and encompasses the entire Metropolitan area. The remaining three models simulate flow in layers 1, 2, and 3, each for a separate hydrologic province. The three hydrologic provinces in the Metropolitan area are defined by the Minnesota and Mississippi Rivers. The software used is the Multi-Layer Analytic Element Model (MLAEM), based on the analytic element method pioneered by Professor Otto D.L. Strack of the University of Minnesota Civil Engineering Department. Improvements in modeling techniques are incorporated into the effort as they are developed to ensure that the Metro Model provides the best technical tool possible for groundwater management issues. Five aquifer layers are represented in the Metro Model. From the top on down they are: 1.Glacial Drift Aquifer (Layer 1), 2.St. Peter Sandstone (Layer 2), 3.Prairie du Chien-Jordan Aquifer (Layer 3), 4.Franconia-Ironton-Galesville Aquifer (Layer 4), and 5.Mt. Simon-Hinckley Aquifer (Layer 5). The models themselves and the data used to support the models are available, either through the MPCA Metro Model website or on CD.
Purpose: The original goals were to assemble databases, develop a conceptual model, and build a regional ground water flow model encompassing the Twin Cities seven-county Metropolitan area. A further goal was acceptance and use of the model by the environmental and ground water modeling community. Regional groundwater models covering the glacial drift to the Mt. Simon/Hinckley aquifers are ready for use. The Metro Model provides a platform from which expansion or development of other subregional models may be developed. And by collecting and reviewing the incremental changes made to the Metro Model, improvements can be shared with all participants. Though originally designed with ground water contamination in mind, other uses that the model can be put to include analyzing ground water management issues such as sustainable development of groundwater, and delineating wellhead protection areas. MPCA believes that the project can also provide support to many different types of hydrogeologic investigations, ranging from relatively simple reviews of geology to more complicated drawdown analyses. A large storehouse of shape files, maps and database files, including Twin Cities bedrock coverages, geostatistically filtered calibration datasets, glacial drift sand-content maps, and stream discharge measurements, are available to all interested parties. These databases can also be used to solve hydrogeologic problems that do not require the building of a ground water model.
