On the Numerical Modelling of Ship Forces During Lockage

Abstract When designing navigation locks, several parameters must be considered: Apart from the construction and operation costs also speed lockage safety considered. The of is often expressed in terms acceptable ship forces. Traditionally, apart physical models different kinds numerical are used to determine operation: During predesign phase simple analytical approaches used, while later design phases more sophisticated one- or three-dimensional independently a hybrid modelling approach. With these flow rates, development water levels resulting forces on can computed measured. While application for lock filling process was past limited very few extraordinary projects, nowadays their becomes engineering practice. Here we giving an overview methodologies presenting state-of-the-art models.
