GMDSI has a series of workshops planned across the world in the second half of 2025. Designed for practitioners, the workshops will showcase real-world case studies in predictive groundwater modelling. From model design and problem formulation to communicating results to decision-makers, the sessions will cover the latest groundwater modelling technology as well as highlight practical […]

Edition 2 of the “PEST Book” has just been released. The book provides complete theory and practice behind simulation-based harvesting of information from site data. It also shows how the integrity of information can be eroded as it passes through a model’s parameters to a model’s predictions, and steps that can be taken to prevent this.

Download a slideshow and an accompanying comprehensive tutorial that demonstrates the use of the MODFLOW 6 Groundwater Energy Transport (GWE) model in simulating an open loop low temperature geothermal system. The model is synthetic but based on a real-world aquifer. A Voronoi grid (generated using ALGOMESH) is employed. Uncertainty is explored using random hydraulic conductivity

This tutorial re-visits DSIVC or “data space inversion with variable control”. DSIVC is a numerically cheap way to undertake optimization under uncertainty. The present tutorial continues a previous tutorial on the same subject by presenting a new (and somewhat more efficient) methodology for achieving similar optimization outcomes. The tutorial also examines circumstances that may challenge
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 course, these choices will be

This tutorial demonstrates some unique features of PLPROC. It shows you how to do some special things, in both deterministic and stochastic ways. These include the following: create alluvial features using splines; move vertices of these features on sliders to change their shapes and locations; populate these features, and a host model grid, using non-stationary,

Description The last few years have seen considerable advances in methodologies and software that can be used in partnership with numerical simulation to support groundwater management and decision-making. These advances are both exciting and daunting. They are exciting because they provide modellers with a smorgasbord of powerful tools that can perform a wide variety of

This comprehensive tutorial demonstrates fast, efficient calibration of a complex 3D model. It complements a previous tutorial on a similar subject. However it shows how calibration results can be better, and can be achieved more easily, with recent software advances. Pilot points are used in an innovative way. They support hydraulic property characterization of a

Description This four-day course will be held over 19th to 22nd November, immediately following the “Simulator partner technologies: When to use, What and Why” workshop. This will also be held at the University of Western Australia. The course will be led by John Doherty; Jeremy White will join us for a day. The course will cover

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 as it is harvested by
