Discharge - GCSE Geography Definition

In GCSE Geography, the term "discharge" refers to the volume of water that flows through a river channel at any given point and is usually measured in cubic metres per second (m³/s). Discharge is important for an understanding of river dynamics. It reflects the amount of water moving through the river system and is influenced by factors such as rainfall, the river's catchment area, and upstream tributaries. Variations in discharge can lead to different river behaviours, such as floods during high discharge or low water levels during droughts, affecting both the surrounding environment and human activities. Accurate measurement and understanding of river discharge are essential for managing river ecosystems, predicting flooding events, and planning the use of water.
