Rapidly Varying Flow

Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, ...

 In open channels, rapidly varying flow, or RVF, occurs when flow depth changes significantly over a short distance, with the rate of change of depth with distance reaching close to 1.

This flow type is complex and challenging to analyze, but approximate solutions are often possible using simplified models.
