MODELADOS COSTEROS

Numerical and physical modelling of dynamic coastal processes.

PRDW

Waves, current, sediment transport and tsunamis are among the phenomena modelled in coastal and maritime projects.

Understanding and quantifying dynamic coastal processes is a critical input for the planning and design of port developments and coastal structures. As specialists in coastal modelling, PRDW have extensive experience in both numerical and physical modelling with over 25 years of experience in each field.

PRDW holds the latest commercial licences for the ‘MIKE by DHI’ suite of numerical models and are acknowledged as expert users by DHI. Numerical modelling applications include:

> Wave modelling (wave refraction and agitation)
> Sediment transport modelling (1D and 2D)
> Hydrodynamics modelling (tsunamis, tropical cyclones and tidal currents)
> Water quality modelling (oil spills, brine discharges and dredge plumes)

Additional models used by PRDW include the CORMIX near-field dilution model, the STFATE dredge disposal model and the SBEACH beach profile model.

Extensive experience in numerical modelling coupled with in-depth practical experience enables PRDW to package cost effective and appropriate numerical modelling studies for each phase of the project life-cycle from pre-feasibility to detail design. Typical numerical modelling studies undertaken by PRDW include:

> Shore protection studies (including determining design conditions for port and coastal structures)
> Estuarine modelling / flood damage
> Beach protection and nourishment hydrodynamics (e.g. sand bypassing schemes)
> Environmental preservation and restoration (e.g. as specialist input for environmental impact assessments)
> Sediment processes investigations (e.g. berth and entrance channel sedimentation)
> Assessment of the impact of sea level rise and climate change
> Cyclonic and tsunami event modelling
> Water quality modelling

PRDW have experience in specifying, managing and processing model results for 2D and 3D physical modelling studies. Typical physical model studies include:

> Armour stability and overtopping assessment of revetments and breakwaters
> Stability and overtopping assessment of seawalls
> Vessel motion investigations
