Hydro-topographic Organization of Rapid Flood Evolution After a Reservoir Breach: Data and Processing Materials

This repository contains derived datasets, statistical products, figure source data, metadata, and processing scripts supporting the study "Hydro-topographic Organization of Rapid Flood Evolution After a Reservoir Breach". The dataset was developed for reconstructing the rapid evolution of flood evidence following the 2026 Liulan Reservoir breach in China using multi-sensor SAR observations. It includes derived flood-evidence products, common-domain flood evolution statistics, hydro-topographic analysis results, source data for manuscript figures, and reproducible processing scripts. The repository supports the analysis of hydro-topographic organization of SAR-observed flood evolution, including river-network connectivity, elevation-dependent patterns, and downstream spatial organization. Original satellite SAR observations are not redistributed due to data access policies and remain available through their respective data providers. This repository only contains derived products and supporting materials generated from the study. The datasets and documentation are provided to enhance transparency, reproducibility, and reuse of the published research results.
