GMDSI
Groundwater Modelling Decision Support Initiative (GMDSI) is industry-funded and industry-aligned. Established in mid-2019, it aims to improve the contribution that groundwater modelling can make to groundwater management, regulation and decision making.
Numerical simulation of groundwater movement and processes is the cornerstone of groundwater management. Data are often scarce and simulator forecasts are therefore uncertain. Nevertheless, decisions must be made, and risks must be assessed. Modelling is pivotal to assessing these risks.
As stated in its modelling manifesto, GMDSI recognizes the important role played by simulator partner software in harvesting information, and in delivering that information to the decision-making process. Simulator partner software is comprised of computer programs that work with simulators to:
- estimate values for their parameters
- explore the uncertainties of their parameters and their predictions
- track the flow of information from data to parameters to forecasts
- optimize decision outcomes with uncertainty taken into account
- optimize investments in future data acquisition.
Many of GMDSI’s activities are devoted to improving the groundwater industry’s understanding of simulator partner software, and to helping groundwater modelers use this type of software. It does this through education and community building. The developers of PEST and PEST++ are among the many people who contribute to GMDSI’s work.
