kanaler

Kanaler is the plural form of kanal in Danish, Norwegian, and Swedish, and refers to a conduit or passage that carries something from one place to another. The term is used across many domains to describe physical waterways, broadcast or data paths, and anatomical passages.

In infrastructure, canals are man-made waterways designed for navigation, irrigation, drainage, or flood control. They connect larger bodies of water, enabling transport and water management. Some canals have historical or strategic importance, and engineering features such as locks and aqueducts are common.

Natural channels in landscapes occur where water flows through sediment or bedrock. River channels, estuaries, and submarine canyons are examples. Channel geometry—width, depth, slope, and planform—affects flow, sediment transport, and ecosystem habitats.

In media and communications, channel refers to a path for signals or information. Television and radio channels distribute programming, while online platforms describe content streams or data channels used for transmitting information.

In biology and medicine, kanaler denote passageways such as ducts and ion channels in cells that regulate the movement of substances. This broad use highlights the idea of a channel as a route for flow and exchange.

The term derives from Latin canalis and entered Scandinavian languages via French or directly, reflecting its broad sense of a connecting passage.
