SUMMARY:Projection-Based Model Order Reduction and Hyper-Reduction for Non-Linear Electromagnetic Problems
DESCRIPTION:On Wednesday\, July 1\, a seminar titled “Projection-Based Model Order Reduction and Hyper-Reduction for Non-Linear Electromagnetic Problems” will be held in Grandori Room (Building 4) at 14:00 CET.\nThe seminar will be given by Prof. Daniel Rixen\, Technical University of Munich. \nAbstract\nOver the last decade\, several new techniques to efficiently reduce non-linear structural problems for transient analysis have been proposed. This seminar will outline the main concepts of projection-based approaches\, in particular how meaningful projection spaces can be constructed and how the computational cost of computing the non-linear forces can be mitigated (hyper-reduction). The ideas will then be extended to electromagnetic problems and to the computation of the associated magnetic forces on structures.

SUMMARY:Fluvial Evolution Mechanisms and Modeling Technologies under Altered Water-Sediment Regimes
DESCRIPTION:On Thursday\, July 9\, as part of a session of two consecutive seminars starting at 10:00 CET\, a seminar titled “Fluvial Evolution Mechanisms and Modeling Technologies under Altered Water-Sediment Regimes” will be held in Grandori Room (Building 4).\nThe seminar will be given by Junqiang Xia\, Professor of River Engineering at Wuhan University. \nAbstract\nThis lecture is Professor Xia’s introduction to the major research work of his team\, covering more than 30 years of studies on “simulation and mitigation technologies for water-sediment disasters”. It consists of three main parts. The first part focuses on bank erosion in the middle and lower Yangtze River\, including failure mechanisms of two-layer structure riverbanks\, in-situ observations of groundwater effects\, multi-scale hydro-sediment-bank erosion modelling\, and ML-based dynamic early warning techniques. The second part addresses sediment transport mechanisms and water–sediment regulation techniques in the Yellow River\, involving reservoir turbidity currents\, movable-bed roughness\, sediment transport capacity under changing sediment regimes\, reservoir-river modelling\, and optimization of water-sediment regulation schemes. The third part examines flood hazards in floodplain and urban areas\, including instability criteria for pedestrians and vehicles\, street-inlet discharge and overflow capacity\, integrated flood evolution and risk assessment models\, drainage-system interactions\, evacuation analysis\, and property-loss estimation. Overall\, the lecture highlights mechanism-based modelling\, experimental investigation\, and decision-support technologies for managing and mitigating water-sediment disasters in large rivers and urban areas.\n\nBio-sketch\nJunqiang Xia is Professor of River Engineering at Wuhan University. His academic career spans more than 30 years\, mainly focusing on modelling and prevention of water and sediment disasters\, especially water-sediment regulation in the Yellow River\, early warning of bank erosion in the Yangtze River\, and mechanisms-based flood risk assessment for floodplain and urban areas. Prof. Xia is a recipient of the National Science Fund for Distinguished Young Scholars and holds the title of Distinguished Professor of Changjiang Scholars. He has been honoured with various national and international awards\, including two awards from the UK Royal Academy of Engineering\, the Chien Ning Sediment Science and Technology Award\, and the Hans Albert Einstein Award of the American Society of Civil Engineers.

SUMMARY:Surrogate modelling for hydromorphodynamic across scales
DESCRIPTION:On Thursday\, July 9\, as part of a session of two consecutive seminars starting at 10:00 CET\, a seminar titled “Surrogate modelling for hydromorphodynamic across scales” will be held in Grandori Room (Building 4).\nThe seminar will be given by Yifan Yang\, Professor of River Engineering at Wuhan University. \nAbstract\nThis seminar presents two complementary surrogate-modelling strategies that learn compact mappings between observable or simulated flow states and otherwise inaccessible or future hydromorphodynamic responses.\nAt the local scale\, an encoder–decoder network learns the relationship between instantaneous surface-flow fields and mean near-bed hydrodynamics\, thereby providing a pathway to infer scour-relevant processes from image-based or remotely sensed observations. Gradient-SHAP analysis identifies localised regions that contain the dominant hydrodynamic signatures\, while a multiresolution strategy combines high-resolution in situ monitoring of critical zones with coarser\, wider-area drone observations. The compressed regions of interest retain sufficient information to reconstruct near-bed fields while substantially reducing data and computational requirements\, supporting the identification of scour progression\, bed mobility and instability.\nAt the river-reach scale\, an Adaptive-Horizon Graph Neural Operator learns bed updating directly on native unstructured meshes while retaining hydrodynamic feedback from a 2D hydrodynamic solver. It maps recent hydrodynamic and topographic states to future bed-elevation increments\, with the effective history length and update interval adapting to the evolving flow–bed system. Trained using validated morphodynamic solutions and evaluated on several benchmarks\, the model reproduces dominant bedform migration\, erosion and deposition patterns while achieving approximately 100x accelerations.\nTogether\, these studies demonstrate a cross-scale pathway from measurement-informed inference to accelerated morphodynamic forecasting\, offering a foundation for rapid scenario analysis\, smart scour monitoring\, early warning\, and hydromorphodynamic digital twins.\n\nBio-sketch\nYifan Yang is Professor of River Engineering at Wuhan University and a recipient of the National Science Fund for Excellent Young Scientists (Overseas). He received his PhD in Civil Engineering from the University of Auckland and previously worked as a lecturer at the University of Waikato\, a postdoctoral researcher at the University of Auckland\, and a civil engineer at Wellington Water. His research focuses on scour and erosion hazards around river and coastal infrastructure\, data-driven hydro-morphodynamics and sediment transport\, and AI-enabled flood risk management and digital twins. He has developed experimental\, numerical and machine-learning approaches for bridge scour prediction\, turbulent flow-field reconstruction\, streambed morphology analysis\, and infrastructure resilience assessment. Prof. Yang is active in international professional service through leadership roles in IAHR and ASCE EWRI committees\, has received the International Leader Fellowship of the Royal Society of New Zealand\, and has led or contributed to collaborative research and engineering projects in China\, New Zealand\, Australia\, and the United States. His work bridges fundamental river mechanics\, intelligent modelling and practical risk reduction.
