Vesistöalueisiin
Vesistöalueisiin refers to the drainage basins or watersheds within a geographical area. These are regions of land where all precipitation that falls drains into a common body of water, such as a river, lake, or sea. The boundaries of a vesistöalueisiin are typically defined by the topography, specifically the ridges and elevated land that separate one drainage basin from another.
The concept of vesistöalueisiin is fundamental in hydrology and water management. Understanding these areas is crucial
Finland, with its abundance of lakes and rivers, has a well-developed understanding and mapping of its vesistöalueisiin.
