Monograph: Decision-Support Modelling Viewed through the Lens of Model Complexity

Leave a Comment / Featured, Monographs /

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) is meant for modellers and

GMDSI Workshop: Focus on the problem. Don’t let the model become the problem

Leave a Comment / Events, Workshops /

There are many management contexts where numerical simulation can productively support environmental decision-making. This is not because it can replicate environmental behaviour very well. (We should drop that illusion.) However decision-focussed simulation can: deliver information to decision-makers and stakeholders in ways that they can understand; deliver the repercussions of lack of information to decision-makers and

Problem Decomposition in Decision-Support Groundwater Modelling

Leave a Comment / Featured, Monographs /

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. Problem decomposition requires that those

GMDSI Tech-Talk: Scripted Workflows vs. GUIs

Leave a Comment / Events, Webinars /

There has been a lot of discussion recently on groundwater modelling workflows – that is, how to build and history-match a model, and then use it to support important decisions. GMDSI’s next webinar explores this topic by hosting presenters from both ends of the workflow spectrum.  Both of our presenters are groundwater modelling heavyweights. They

The Regulatory Framework: Consultations and Discussions

Leave a Comment / Featured, Monographs, Workshops /

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 (Office of Water Science), and
