I am very glad that our article Identifying relevant hydrological and catchment properties in active subspaces: An inference study of a lumped karst aquifer model was accepted for publication in Advances in Water Resources (Elsevier).
As before, this article comes out of a collaboration between the teams at TUM within the UNMIX project. Daniel Bittner and Gabriele Chiogna from the TUM Chair of Hydrology and River Basin Management and Steven Mattis, Barbara Wohlmuth, and I from the TUM Chair for Numerical Mathematics were interested in hydrological inferences that can be drawn out of looking at subspaces that are dominant for the behavior of karst systems. In particular, we studied a karst aquifer model that was applied to the Kerschbaum spring in Waidhofen a.d. Ybbs in Austria and used the active subspace method as a technique to study parameter sensitivities and correlations.
Congratulations to Daniel! I also want to thank everyone who contributed to this article and made this a valuable scientific contribution!
