SEGLISTS: Interpolation along linear features

This tutorial demonstrates several options for spatial parameterization of linear and polylinear features. In a groundwater model, these may represent entities such as streams, rivers, faults, or fracture networks. The hydraulic properties of these features may vary along their lengths. If this variability is relevant for a prediction of interest, then its representation in a …

PLPROC: a simple pilot point example

PLPROC allows a modeller to create and manipulate parameters that inform hydraulic properties that are represented in a numerical model. In doing this, PLPROC supports PEST in facilitating model-based decision-support which enshrines the principle that a model should encapsulate what we know and quantify what we do not. This tutorial offers a gentle introduction to …

Webinar series attracts international audience

Predicting the future of any environmental system is fraught with uncertainty; nevertheless, decisions must be made and risks must be assessed. This is where decision support comes in. The Groundwater Modelling Decision Support Initiative, an industry-aligned project supported by BHP and Rio Tinto sitting within the College’s National Centre for Groundwater Research and Training, recently …

Webinar series: Decision-Support Modelling Principles and Practice

In May and June 2020, GMDSI offered a four-part webinar series on decision-support modelling principles and practice. John Doherty and Catherine Moore presented the first three of these webinars, while the fourth was presented by John Doherty and Jeremy White (USGS and co-author of the PEST++ suite). The webinars were chaired by Craig Simmons (NCGRT), …
