TIDAL RIVER Meaning and
Definition
-
A tidal river refers to a river that experiences the influence of tides, which are periodic rises and falls of the water level caused by the gravitational forces of the moon and the sun. Unlike non-tidal rivers, tidal rivers are directly connected to the ocean or another large body of water, allowing the tides to extend upstream along the river's course.
The distinctive feature of tidal rivers is the presence of a noticeable tidal range, which determines the water level fluctuations within the river. During high tide, the seawater enters the river, filling it up and causing the water level to rise. As the tide recedes, the water level drops, resulting in low tide. This rise and fall of the tide in tidal rivers occur twice in a day and can significantly impact the characteristics of the river's flow, such as its speed and direction.
Tidal rivers often exhibit unique ecological features, creating diverse and dynamic ecosystems. These rivers support various types of vegetation, including salt-tolerant plants, and foster the development of estuaries, where freshwater from the river mixes with saltwater from the sea. These environments become habitats for a wide range of organisms, including fish, birds, and marine mammals, which rely on the tidal movements for feeding, breeding, and migration.
The tidal river phenomenon has also influenced human activities throughout history. People living near tidal rivers have established settlements, built ports and harbors, and engaged in fishing, trade, and transportation. The ebb and flow of the tides have contributed to shaping the economy and culture of these communities, establishing a unique relationship between humans and the natural dynamics of tidal rivers.
