What does channelization involve?

Channelization is a process that involves altering a stream channel to improve the efficiency of water flow. This can include straightening the path of a river, deepening the channel, or removing obstacles such as boulders and vegetation that can impede flow. The goal of channelization is often to reduce flooding risks, enhance water conveyance, or increase the navigability of waterways.

Altering a stream channel can significantly influence the surrounding ecosystem and hydrology, impacting sediment transport, aquatic habitats, and the overall health of the stream environment. Understanding this process is crucial in water resource management and environmental conservation, as channelization can have both positive and negative effects on the environment, depending on how it is implemented and managed.
