The short course on ‘Hydroinformatics for hydrology’ was run at vEGU21 for the sixth time already, but due to the pandemic the first time as a virtual version. Dmitri Kavetski managed to present a broad overview of ‘Bayesian methods in environmental modelling and data analysis’, including various applications and the theory behind. Bayesian methods is another short course that provides a deep insight into a certain topic of general interest from an experienced researcher who is happy to share his knowledge with others. We would like to thank Dmitri Kavetski for holding the short course and sharing his slides, which can be found here:
