Uniform flow in an open channel exists when the: Correct Answer Channel is prismatic and the depth of flow is constant along the channel.

Open channel flow is said to be uniform when depth and velocity are same at every section of channel. Hence it follows that uniform flow can occur in prismatic channel.
