The book is divided into nine chapters. The first
three chapters introduce the subject, describe the
core framework data model, and present an exposition
of how to represent 3D objects in ArcGIS.
The next three chapters present components of
the groundwater data model for geological mapping,
wells and aquifers, and 3D hydrostratigraphy.
The final three chapters describe time series,
groundwater modeling, and implementation of
the groundwater data model in ArcGIS.
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.
