Development of a Great Lakes Groundwater and Surface Water Conceptual Framework

1.5 Organization of this document In addition to this introductory section, the report includes the following sections: • Section 2 summarizes the methodology used to conduct the study • Section 3 covers the management elements of the conceptual framework • Section 4 summarizes the scientific and technical elements of the conceptual framework that should be incorporated into a future GW-SW model •. [...] 2.1 Developing management elements of the conceptual framework The approach to developing management elements of the conceptual framework to create and operate a GW-SW model for the basin began with identifying the types and roles of stakeholders (Table 1, next section). [...] In the summer of 2021, the US National Weather Service (NWS) extended the National Water Model into the 2 Note that the effects of climate change on the water cycle, especially the groundwater system, in the Great Lakes basin are largely unknown, as this has not been a focus of investigations in most regions of the basin. [...] The selection of the most appropriate set of models is a function of the main objective for the simulation of the hydrologic cycle. [...] Finally, the computational burden of two- and three-dimensional models makes the consideration of that class of models to be unfeasible for the objectives of the Great Lakes integrated surface and subsurface model.
