Numerical modeling is an important tool for understanding water dynamics and the processes associated with it. Whether reproducing past events or projecting the future, we assess and optimize designs so that they are safe, cost-efficient and environmentally sustainable.

  • Salinity and temperature modeling
  • Harbour agitation and overtopping simulation
02

Sediment transport and morphodynamics

  • Cohesive and non-cohesive sediment transport modeling

Studies for the rehabilitation of inlet jetties

Multibeam and topographic surveys with a 3D model of the structures, wave and current measurements, shallow seismics and numerical modeling to support the design of the jetty rehabilitation and channel dredging and rock removal.

Dynamic under-keel clearance (UKC) analysis

Calculation of the dynamic UKC of the access channel for each draught and speed, combining tide, waves, squat and ship response, in place of the static rule. The outcome is the feasible draughts and tidal windows for each condition, the gain in operability and the comparison between channel alignment alternatives, with the sedimentation predicted by morphodynamic modeling.
