Answer Details
The seasonal variation in the volume of water in a river is known as its regime. The regime refers to the fluctuations in the discharge or flow of a river throughout the year due to changes in precipitation, temperature, and evapotranspiration. The regime of a river is influenced by the climate and weather patterns of the surrounding area and can have significant impacts on the ecology and human uses of the river. The regime can be classified as perennial (constant flow throughout the year), intermittent (flow only during certain times of the year), or ephemeral (flow only during and immediately after precipitation events).
