As a journal dedicated to the international field of water science, the importance of LHB Hydroscience Journal is self-evident. Water is one of the most precious resources on Earth, not only related to human survival and development, but also an indispensable component of multiple industries such as agriculture, industry, energy, and transportation. This journal is dedicated to publishing and disseminating the latest research findings and innovative engineering practices in the field of water science, providing a platform for communication and learning on the sustainable management and utilization of global water resources.The journal covers a wide range of topics, including but not limited to hydrological cycles, meteorology, flood prediction and management, drought and low flow issues, environmental risk assessment, and water resource management. These fields are crucial for understanding the complexity of the water cycle, predicting and responding to extreme hydrological events, protecting the water environment, and improving water resource utilization efficiency. We also pay attention to fundamental scientific issues such as fluid mechanics, multiphysics processes, and multiphase flow. These studies help deepen our understanding of water flow and transport mechanisms, providing theoretical support and technological innovation for fields such as hydraulic machinery design, energy production, and microfluidic technology. Through these studies, the journal has advanced water science and technology, promoted efficient utilization and protection of water resources, and provided scientific basis and solutions for addressing global water scarcity and environmental issues.
