The main changes in the v2.2 release of November 2022 are:
- Streamlined and more transparent calculation method of aquifer properties. While this does not change the national trends of the properties, the predictions have become more reliable;
- Calculation of net to gross ratios and porosity of aquifers using Machine Learning techniques (previously fixed net gross ratios were assumed per aquifer, now they are calculated from well log data);
- The technical descriptions of Aquifers, Aquifer Properties and the Calculation Model have been updated and expanded;
- The Brussels Sand Member has been completely re-mapped;
- Adaptation of the 'look and feel' of the website.
