By writing the momentum equation in the system of normal coordinates (in the direction of flow and perpendicular to the flow direction) for a volume control of the fluid, the equations (4) and (5) can be obtained:
To establish relations between the equations of flow and the spillway geometry, the normal coordinates system of the flow is expressed as Cartesian coordinate system.
The initial layout of the graph is called the normal view of the graph, and its coordinates are called normal coordinates.
