The Numerical Groundwater Modelling courses (Flow Modelling: 29.8.-2.9. and Transport Modelling 5.-9.9.22) were well attended even after Corona and despite (or because of?) keeping the online format. Besides 12-15 students from the MSc courses in Halle, there were also 4 participants from New Delhi. Therefore, the course was again held in English. This year, the format was changed to working on a model task very independently in groups using different tools and sharing experiences in presentations. For next year, the course is planned for the period 4-15.9.23. In addition to our university students, external participants will also be welcome and there will certainly be some Indian participants in attendance.
