CNSW 1.0: Prefectural Reconstruction of China's Surface Water Resources Using Machine Learning Methods.

ABSTRACT: A comprehensive and long-term dataset of prefectural surface water resources is crucial for effective water resources management in China. However, there has been a significant gap in the availability of such datasets, with no existing datasets providing comprehensive long-term coverage. To address this gap, we have developed CNSW 1.0, the first long-term (2000-2020) dataset of prefectural surface water resources in China. Utilizing surface water resources data from official water resources bulletins, we employed 14 advanced machine learning models to reconstruct the CNSW 1.0 dataset. The resulting dataset exhibits high accuracy, with an R² of 0.98 for total surface water resources and acceptable level of bias across China. CNSW 1.0 not only outperforms existing datasets like CN
