High-resolution Chinese Extreme Flooding Data in 2010 and 2020, 30m*30m

This dataset provides a detailed analysis of extreme floodings in China for the years 2010 and 2020. It offers high-resolution (30 meters x 30 meters) raster data products designed to enhance the understanding of extreme rainfall events and their environmental impacts, providing scientific support for flood prevention planning, land management, and water resource protection. Application ScenariosThese data can be applied across various research fields, including but not limited to climate change impact assessment, disaster risk management, and ecosystem service evaluation. Additionally, it serves as an educational resource, assisting students and researchers in better understanding how GIS and modeling simulations can address real-world problems. Key Features: Temporal Coverage: Data represents two specific years, 2010 and 2020. Geographical Scope: China, including the Special Administrative Region of Hong Kong. Macau and Taiwan are not included due to a lack of data. Format: Two final raters files at a high resolution of 30m x 30m. Processing Tool: The InVEST software was utilized for modeling and analysis. *Please note that the study does not simply use the data for 2010 and 2020 but averages the number for that year and the two years before and after. This means that 2010 is the actual period from 2009 to 2011, and 2020 is the actual period from 2019 to 2021. Researchers should cite this dataset and relevant paper when using it in publications or presentations.
