This research was funded by the BMBF (Bundesministerium für Bildung und Forschung) Germany, as part of the project STUCK (FKZ: 033W031) within the FONA³ (Forschung für Nachhaltigkeit) funding measure ReWaM (Regionales Wasserressourcen‐Management). This study contributed to the Cluster of Excellence CLICSS (Climate, Climatic Change, and Society) and to CEN (Center for Earth System Research and Sustainability) of Universität Hamburg. Special thanks also to the LSBG (Landesbetrieb für Straßen, Brücken und Gewässer) for their project coordination and to the Bezirksamt Eimsbüttel and Bezirksamt Bergedorf for their permission to work within the Kollau and Dove‐Elbe area. I would like to thank my supervisor Annette Eschenbach for her support during my PhD.
Working on a doctoral thesis, as a mother of a little child, is only possible if a flexible working time is created ‐ thank you very much for that! The continuous panel meetings were very helpful in completing my doctoral thesis. Many thanks to SICSS (School of Integrated Climate System Sciense) for setting up these meetings and many thanks to Annette Eschenbach, Alexander Gröngröft, Kai Jensen and Felix Ament for their regular participation and helpful
comments. Furthermore, I would like to thank Alexander Gröngröft for his help with designing experimental concepts and the data assessment. I would also like to thank Volker Kleinschmidt for his help during the soil surveys and setting up field experiments. Without the support in the lab, no doctoral thesis in soil science is possible, many thanks to Monika Voss, Angelika Meier, Deborah Harms and Sumita Rui for that! Special thanks go to Jana Bräuner for her long time of support. Without her help, some of the field and lab experiments would not have been
possible, due to the great amount of time involved.
