The definition and classification of water resources are the basis of conducting water resources research and management. The construction of the disciplinary system of water resources science is of great significance to the future development of the discipline. The classification of water resources further clarifies the research objects of water resources and is the basic content of constructing the disciplinary system of water resources science. Based on a framework of multi-principle, multi-dimension, and multi-category, a new classification scheme of water resources was put forward, which includes 26 categories in 9 dimensions. On the basis of summarizing the development history of water resources science, this study constructed the disciplinary system framework of water resources science, clarified the research objects of water resources science, and identified representative theoretical systems including the principle of water balance, the theory of water resources value, the theory of sustainable use of water resources, and the theory of human-water harmony. It also summarized the methodology covering monitoring and simulation methods, water resources models and other methods, and a series of applications. Considering the classification of water resources, the branches of water resources school are discussed from different perspectives, as well as the prospect and development directions of the research of water resources science. This study provides a reference for the research and management of water resources and the disciplinary development of water resources science.
