Abstract: In recent years, affected by the climate change impacts and the growth of human activities, the frequency of extreme flood events in the Haihe River Basin shows an obvious increasing trend. To support sustainable basin water management, a novel Matrix Hydro-modelling System integrating multiple models and modules has been developed. This system enables the simulation and forecasting of flood processes under the influence of defense measures in the Haihe River Basin. The system employs a six-dimensional matrix architecture encompassing time, space, application, algorithm, parameter, and boundary variables. On one hand, the matrix architecture gives higher flexibility for users to re-set up various models into several modules to represent the flood processes, on another hand the modules consisted in the system is easier to be categorized into different groups according to their physical representation and run in parallel. The Matrix Hydro-modelling System has been applied for representing the catastrophic flood happened in 2023 in the Haihe River Basin and future to be used for evaluating the effects of the flood defense measures. With 0.7 NSE value in averaged of Daqing river’s stations, the modelling results approved the higher applicability of the proposed “matrix architecture” which can be easily implemented in other river basin with similar characteristics.
