Physical simulation of hydrodynamics and sediment transport at a river mouth
The basin can be equipped with up to three computer-controlled portable wave machines capable of producing a wide variety of irregular long-crested waves with heights up to 0.2 m. Large pumps and weirs under computer control can be used to produce tidal flows and simulate discharges from inlets, rivers and culverts. Discharges up to 1.6 m3/s (56 cfs) can be generated by tapping into the adjacent High Discharge Flume. The LAB can be quickly drained and filled, and can be easily accessed by construction equipment for building model bathymetries and structures. The facility is typically used to conduct large three-dimensional model studies of:
- marinas, ports and harbours;
- ship mooring and berthing;
- coastal processes and nearshore circulation;
- sediment transport, beach response and shoreline developments;
- open channel flows in estuaries, rivers, canals and inland waterways;
- the responses of moored ships to winds, waves and currents;
- wave interaction with coastal and maritime structures;
- scour, erosion and mitigation methods.
