  abstract = {{T}his paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. {T}he procedure involved a public consultation through online media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. {I}n spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. {Q}uestions remain focused on the process-based understanding of hydrological variability and causality at all space and time scales. {I}ncreased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. {I}n particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. {W}e hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come.},
