River

A river is a natural flowing watercourse, usually freshwater, that moves continuously through the landscape, typically from higher to lower elevations. It collects water from rainfall, tributaries, and underground sources, carving valleys and shaping the terrain. Rivers are vital ecosystems, supporting diverse plants and animals, and serve as essential resources for human activities such as drinking water, agriculture, transportation, and industry. Their flow can vary seasonally, influenced by rainfall and snowmelt. Overall, rivers are dynamic features that connect landscapes, ecosystems, and human communities.
