AB  - This dataset contains levee leakage disaster information from the Chaohu area for the years 2016 and 2020, aimed at providing comprehensive support for levee leakage risk prediction and assessment. The data was collected through a combination of remote sensing monitoring and field surveys, covering the Chaohu area with a temporal and spatial resolution at the annual and locational level. The data is named using a standardized format that includes the year and location of the disaster, facilitating management and query. The 2016 data includes levee leakage distribution maps for Chaohu City, Tongyang River, Yuxi River, Zhao River, and Zhegao Levee; comparison maps of disaster situations between 1991 and 2016; flood inundation comparison maps; the 2016 hazard statistics table; and the Lujiang floodgate overflow registration form. The 2020 data further supplements the disaster evolution, including levee hazard analysis for the Chaohu basin (by city and river), flood inundation data for Hefei City, flood control work briefs, breach statistics, hazard analysis for Ma’anshan, and overflow and flood storage data for levee breach locations. This dataset provides high temporal and spatial coverage and includes specific geographic coordinate information, effectively supporting levee leakage risk prediction, disaster early warning, levee safety monitoring, and leakage risk assessment. Through comparative analysis of the 2016 and 2020 disaster data, this dataset offers valuable information for research, decision-making, and disaster prevention in relevant fields.
