LOCKFILL

In order to limit the delay for navigation it is of importance that the operation of a navigation lock progresses smoothly and within a minimum of time. Therefore, it is desired that the process of filling and emptying of the lock chamber is executed at the highest possible pace.

However, lock operation must also be safe from the shipping point of view; this requires that the hydraulic forces on the ships in the lock chamber, and in particular the longitudinal forces, remain acceptable during operation and that the rise or drop of the water level in the lock chamber occurs at a moderate rate. Because the latter demands are directly related to the layout of the filling and emptying system and the way this system is operated, a carefully designed system is required.

Deltares has developed the calculation program LOCKFILL. This program enables an accurate simulation of the locking process and it computes the hydraulic forces on a ship in the lock chamber.
