Morphology

channelization = channelize (transparent) = channel + ize + ation

Built regularly from 'channel' -> 'channelize' -> 'channelization'; in this sense the term denotes the literal engineering process of forming or modifying a channel, which is directly inferable.

Etymology

Channelization comes from channel and the old word canal, which means 'a pipe or waterway'. That gives a clear image: to channelize a river is to make or change its channel so the water flows where people want, which is why channelization refers to changing waterways to control their flow.
