Surface and subsurface hydrologic models (SSHM) simulate the relevant components of the water cycle that affect surface water and groundwater. Such models thus constitute important tools to support water resources management. This session seeks presentations that focus on technical advances or/and practical applications of SSHM for water resources management. We welcome present solutions including data assimilation for informing model calibration, comprehensive uncertainty analysis, the parametrization of surface and subsurface properties, the conceptualization of relevant flow and mass transport processes, the improvement of computational efficiency of SSHM by using novel computing methods and supercomputer systems, or the integration of SSHM with other models (e.g., biological and ecological models, atmospheric models, land subsidence models, or machine learning models). We also encourage presentations that showcase examples where numerical modelling tools are employed to manage water use, water pollution, prediction and prevention of water-related disasters (e.g. storm surges, tsunamis, droughts or stormfloods), evaluation of dynamics of water cycles under the ongoing climate change and sea-level rise, or real-time forecasting to support decision-making.
