Catchments are coupled human-natural system composed of components with complex behaviour and nonlinear interactions. Climate variability, change, and extremes (e.g. droughts and floods); vegetation dynamics; land use and land cover; flow regulation and other human developments all influence catchment behaviour. There are myriad unknowns about the variability and change of these components and their impacts on the catchment response (i.e. streamflow dynamics), which pose a great challenge both to explain and model the underlying processes of these components. Yet the need for reliable modelling, particularly under changing conditions, is stronger than ever, as reflected by its inclusion among the Unsolved Problems in Hydrology (https://doi.org/10.1080/02626667.2019.1620507).
In this session, we welcome contributions aimed at tackling the above problems within modelling themes such as (but not limited to)
