Update of the Twin Cities Metropolitan Area Regional Recharge Model
Regional recharge modeling with the Twin Cities daily soil water balance (SWB) model has been a fundamental part of the Metropolitan Council’s groundwater flow modeling effort and supports the Metropolitan Area Master Water Supply Plan. The SWB model is used to evaluate the impact of planned and potential land use and climate on recharge in the eleven-county metropolitan area, and supports the ongoing update of the regional groundwater flow model. Project objectives included: 1) incorporating new information into SWB recharge model; 2) expanding the extent of the SWB recharge model; 3) adding the capability to run predictive simulations with the SWB recharge model, and 5) evaluate SWB recharge model uncertainty. This data is currently being incorporated into the regional groundwater flow model.
$500,000 the first year and $500,000 the second year are for implementation of the master water supply plan developed under Minnesota Statutes, section 473.1565.
This project proposes to update the Soil Water Balance (SWB) recharge model, which will improve the Metropolitan Council’s capability to accurately predict recharge in the eleven-county metropolitan area under different land use and climate scenarios. The recharge values generated by the SWB model will also support update of the regional groundwater flow model.
The update of the Soil Water Balance (SWB) recharge model improves the Metropolitan Council’s capability to accurately predict recharge in the eleven-county metropolitan area under different land use and climate scenarios. The recharge values generated by the SWB model are currently being entered into the updated groundwater flow model.

The update of the Soil Water Balance (SWB) recharge model improved the Metropolitan Council’s capability to accurately predict recharge in the eleven-county metropolitan area under different land use and climate scenarios. The recharge values generated by the SWB model also supported the update of the regional groundwater flow model, Metro Model 3.
