水系

水系 (shuǐ xì) refers to a network of rivers, streams, and other water bodies that are connected and drain into a common outlet, such as a lake or ocean. It is often used in geographical contexts to describe the entire drainage system of an area.

The character 水 (shuǐ) means 'water,' and 系 (xì) means 'system' or 'network.' Together, they form a term that describes the structured flow and distribution of water across a landscape.

水系 is commonly used in geography, environmental science, and urban planning. Understanding a region's 水系 helps in managing water resources, preventing floods, and protecting ecosystems. It is also a key concept in studying the natural environment and human interaction with it.
