Schematizing wave boundary conditions in sediment transport modeling around a harbour: A case study for Salaverry-harbour, Peru

For many applications in the field of coastal engineering 2D-morphological models are being applied. Due to the large computational effort these models demand it is nearly impossible to include a full wave climate in long-term morphological modeling. This has asked for waveclimate reduction methods in order to reduce the input and consequently...

Boundary Conditions for a Seiche model

The Storm Surge Barrier in the New Waterway was built to protect the city and port of Rotterdam and the area of the lower Rhine against flooding during extreme conditions. This construction, consisting of two gigantic arc shaped barriers, is to be pivoted into the New Waterway and then lowered in case of an impeding emergency. The arc shape...

The feasibility of implementing radiating boundary conditions in Triwaq

This report describes a method for radiating disturbances generated in the computational field through the radiating boundaries. First a simulation is made without disturbances (such as a storm surge) subsequently a second simulation is made with the radiating boundary conditions activated, and the disturbance is able to pass through the...

Experiments and computations on unsteady separating flow in an expanding flume

An unsteady, separating flow with a free surface was investigated with a physical model and a numerical model. To simulate tidal flow, the prescribed flow rate at the inflow boundary was a half-period sine function of time. Measurements of velocities and wave heights were conducted by using LDV and a wave-height meter in a straight open channel...
