🔑 Key Concepts & Definitions

• River Drainage Basin: The area where all precipitation and groundwater flow into the main river via tributaries. It is bounded by watersheds, such as mountains or elevations, which separate adjacent basins. (Source: provided content)

• Watershed: A natural boundary that separates one drainage basin from another, typically formed by geographies like mountain ranges or elevations. It determines the extent of a river's drainage area. (Implied from source content)

• Flow Regime: The distribution of water flow in a river over a period, influenced by precipitation patterns and water sources. A mixed river, like the Rhine, has a more uniform flow regime compared to a rain river. (Source: provided content)
