What is referred to as a junction in a river?

A junction in a river refers to a point where the river divides or branches off into separate channels as it proceeds seaward. This is a key concept in understanding river geography, as these junctions can have a significant impact on navigation, sediment transportation, and the overall ecology of the area. The formation of a junction usually indicates that the river is either reaching a larger body of water, such as an ocean or a bay, or is distributing its flow into tributaries.

Understanding the concept of a junction helps mariners anticipate changes in water flow, potential hazards, and the best routes to navigate through river systems. This knowledge is crucial for safe operation of vessels in waterways where river currents and navigation can be affected by these divisions.
