Catchment Functioning Under Prolonged Drought Stress : Tracer-Aided Ecohydrological Modeling in an Intensively Managed Agricultural Catchment

Acknowledgments Data used in this study are obtained from the Terrestrial Environmental Observatories (TERENO) project and the Modular Observation Solutions for Earth Systems (MOSES) project, both initiated and funded under the Earth and Environment Program of the Helmholtz Association, Germany. The authors highly appreciate efforts of all partners involved in different monitoring activities. Specifically, The authors would like to thank Frido Reinstorf and Florian Pöhlein from University of Applied Sciences Magdeburg‐Stendal for sharing the hydroclimatic and groundwater level data; Kay Knöller, Ralf Merz and Christin Müller, from Department of Catchment Hydrology (UFZ), for sharing the data of stable isotopes of water and for the constructive discussions; Hans‐Jörg Vogel, Holger Rupp and Ralf Gründling, from Department of Soil System Science (UFZ), for sharing the lysimeter soil moisture data. The authors thank the Editor, the Associate Editor, and three reviewers (Trish Stadnyk and two anonymous reviewers) for their constructive comments. The data are presented in the tables, figures, and supplements. The authors would like to thank Marco Maneta for his support and discussion on the modeling. Contributions from C. Soulsby were supported by the Leverhulme Trust's ISOLAND project.Peer reviewedPublisher PD
