A long prismatic channel ends in an abrupt drop in bed. Which one of the following statements explains the water surface profile on the upstream of the drop for an initially sub critical flow?
1
Water surface profile lies completely below the critical depth line
2
Water surface profile lies between critical and normal depth line
3
Water surface profile lies between critical depth lines and joins the normal depth line asymptotically
4
Water surface profile lies completely above the normal depth line
