Metropolitan Area Ground Water Model - The Metro Model - and Supporting Data

Metadata Updated: November 12, 2020

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.
