AI Technical Summary

Technical Problem

Existing watershed flood simulation systems suffer from problems such as single data sources, delayed updates, static models, difficulty in integrating heterogeneous spatiotemporal resolution, accuracy, and semantic consistency of multi-source data, and a disconnect between runoff generation processes and flood evolution dynamics in small and medium-sized watershed flood simulations, as well as the difficulty in quantifying the hydrological effects of natural intervention measures.

Method used

The watershed is monitored by using multi-source data acquisition. Data is integrated through multi-source data preprocessing and spatiotemporal cross-modal interactive fusion methods to construct a distributed hydrological-hydrodynamic coupling model. This enables dynamic simulation of the entire process from runoff generation to flood evolution in the river channel and floodplain, and is combined with digital twin watershed modeling and visualization.

Benefits of technology

It improves the accuracy and robustness of watershed flood simulation, provides scientific support for flood risk assessment and natural flood control measures in small and medium-sized watersheds, and offers dynamic simulation and visualization with high spatiotemporal resolution.

Abstract

This invention relates to the field of flood disaster simulation technology, and in particular to a watershed flood dynamic simulation system based on multi-source data fusion. The system includes a multi-source data preprocessing module, a multi-source data fusion module, a digital twin watershed modeling module, a flood dynamic simulation module, a flood risk assessment module, and a visualization module. This solution proposes a spatiotemporal cross-modal interactive fusion method to fuse multi-source data. This method introduces a cross-modal interaction mechanism to capture intramodal dependencies and uses low-rank decomposition to efficiently fuse high-dimensional interaction tensors, taking into account the complementarity of spatial topology, temporal dynamics, and multi-source heterogeneous data, effectively improving the accuracy and robustness of hydrological process modeling. By constructing a distributed hydrological-hydrodynamic coupled model, it achieves dynamic simulation of the entire process from runoff generation to flood evolution in the river channel and floodplain.
