IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Hydraulic design of a filling emptying system for the new royers lock in the portof antwerp (belgium)

ABSTRACT
An upgrade of the present Royers lock at the right bank of the tidal river Scheldt is planned by the Flemish administration
and the Antwerp Port authorities. This implies a widening of the lock chamber towards 36 m and a lengthening towards
250 m. The new lock is designed for inland navigation. The design convoy consists of an ECMT class VIb ship and an
ECMT class Vb ship. The selected filling and emptying system for the new lock is to a great extent a downscaled version
of the one in the existing maritime locks in the Port of Antwerp, i.e. short bypass culverts in the lock heads. This paper
wants to give an account of the hydraulic modelling efforts carried out during the design of this system.
First, a 1D hydraulic network model is set up with the LOCKSIM software, based on head loss data from literature as well
as from a similar model for the Berendrecht lock that was calibrated with field measurements. The 1D model is used to
verify that the defined system meets the specified criteria on filling and empting time and water surface slopes, when use
is made of an appropriate opening law of the vertical lifting valves in the culverts.
Secondly, the complex 3D flow upstream, inside and downstream of the culvert outlets in the lock chamber is investigated
by means of CFD simulations with the OpenFOAM software. These simulations show that the uniformity of the filling
discharge into the lock chamber is acceptable. Additionally, the simulations confirm that the highest flow velocities in the
lock chamber during filling are situated inside the deepened section of the lock chamber floor, which is favourable to
minimize (direct impact) forces on ships moored close to the culvert outlets.
