What is the output of a river?

The output of a river, often referred to as its discharge, is the volume of water flowing through a river at a given point over a specific period, typically expressed in cubic meters per second (m³/s). This discharge is influenced by factors such as rainfall, snowmelt, and upstream water usage. Additionally, the output can affect the river's ecosystem, sediment transport, and surrounding environments. It plays a crucial role in shaping landscapes and supporting biodiversity.
