Applied hydrogeology requires application of conceptual models to represent the conditions for groundwater flow which are key to solving groundwater development and contamination problems. Understanding groundwater conditions begins with understanding geology and using that geological information to estimate hydraulic conductivity and porosity. In turn, the distribution of hydraulic conductivity and porosity inferred from geologic information are used to create hydrogeologic representations of a groundwater flow system. Prior to the 1970’s, this conversion was accomplished using pencil and paper but now it is done using readily available software. However, to use the software effectively, it is essential to understand this conversion process. This book: Geologic Frameworks for Groundwater Flow Models by J.P. Brandenburg is an introduction to the conversion process that has become well established in the petroleum industry but has lagged behind in the hydrogeology industry. Hydrogeologists know that three-dimensional numerical flow models are essential, but it is the conversion from geologic data to the hydrogeologic model that needs clearer recognition. This conversion is known as: ‘static modeling’, which is the precursor to ‘dynamic modeling’. Dynamic modeling refers to the flow and transport modeling (i.e., aquifers do not move so are static, but the fluids are in motion so are dynamic).

J.P. Brandenburg, author of this book, is exceptionally qualified for the task because he is extensively educated in both geology and fluid flow; has undertaken conversions for sophisticated static and dynamic modeling in the petroleum industry; and currently is focused on conversions for complex three-dimensional groundwater models.
