Monographs
Occasionally, GMDSI publishes a monograph on a subject of importance to decision-support modelling that is not necessarily technical. Their purpose is to cogently and respectfully challenge ways in which decision-support groundwater modelling is traditionally undertaken using arguments that are based on logic and experience. Hopefully, these arguments are presented in ways that make them easy to read by modelers as well as by non-technical stakeholders in model-based groundwater management.

Decision-support modelling self-questionnaire
This short document presents a series of questions that may help you to design a decision-support groundwater model. It is not long; it takes three minutes (or less) to read.The intent of these questions is to help modellers think about their design choices as they build a decision-support model. Of
Decision-Support Modelling Appropriateness and the Journey of Information
This short monograph packs a lot of punch. It starts by solving an almost trivial, nonunique inverse problem. While simple, the problem is typical of many that are encountered on an everyday basis in decision-support groundwater modelling. Solution of this problem provides important insights into the journey that information takes
Monograph: Decision-Support Modelling Viewed through the Lens of Model Complexity
What should decision-support groundwater modelling seek to accomplish? Should it try to build a digital replica of what happens underground? Obviously not, because this is impossible. Not nearly enough is known about the subsurface and its hydraulic properties to do this. This monograph (written by John Doherty and Catherine Moore)
Problem Decomposition in Decision-Support Groundwater Modelling
Decision-support groundwater modelling is as much an art as it is a science. Much of the “art” is in decomposing the management problem that modelling must address. If this is done properly, then decision-support modelling has a much greater chance of being useful to decision-makers, while being acceptable to stakeholders.
The Regulatory Framework: Consultations and Discussions
The last in a series of meetings that GMDSI hosted on the groundwater regulatory framework was held on August 18th, 2022. This meeting (attended by 73 people, most of whom were not regulators) discussed the use of groundwater modelling in the regulatory framework. After a brief introduction by Peter Baker
Scientifically-Based, Decision-Support Groundwater Modelling
GMDSI is preparing a two-part book. A draft of the first part of this book is now available. Authored by John Doherty, it provides a comprehensive conceptual framework for decision-support groundwater modelling. Based firmly on scientific principles, it suggests ways in which modelling can better serve the imperatives of environmental
Decision-Support Groundwater Modelling: A Game
This game illustrates ideas presented in an accompanying interactive video. Like the video, it was developed by Ty Ferré of University of Arizona. The game is simple but powerful. It resides in an Excel spreadsheet. So you don’t need an expensive video card to play it. And perhaps it is
Interactive Video: A Conceptual Representation of the Phases of Groundwater Model Development and Application for Users at all Levels
Groundwater modelling needs a context to make sense. This context is set by a decision that must be made, by those who must make that decision, and by those who are affected by it. The context for the decision itself is set by adverse consequences that groundwater management seeks to
