It is important to understand some of the limitations of this book — we are describing an information model for groundwater data.
This is not a book about groundwater simulation modeling.
Arc Hydro Groundwater can be used to help create groundwater simulation models and to store the results of groundwater simulations, but Arc Hydro Groundwater is not itself a groundwater simulation model.
Likewise, although we devote considerable attention to hydrogeology, Arc Hydro Groundwater is not intended to capture all the detailed cartographic aspects of geologic and hydrogeologic mapping. Our focus is on the groundwater environment and on the properties of the water flowing through that environment
