WebMar 2, 2024 · Normal Depth: For a given channel geometry, slope, and roughness, and a specified value of discharge Q, a unique value of depth occurs in a steady uniform flow. … WebThe flow depth in uniform flow is called the depth yn 3. The varied flow is called (RVF) if the flow depth changes markedly over a relatively short distance in the flow direction (such as the flow of water past a partially open gate or shortly before a falls), and (GVF) if the flow depth changes gradually over a long distance along the channel.
