The Hydrodynamic Module can be applied to computational domains using either structured rectangular grids (single or multiple nested domains) or unstructured flexible meshes (finite-element grids). Simulations may be performed using two-dimensional (2D) models to represent horizontal hydrodynamic processes or three-dimensional (3D) models to simulate both horizontal and vertical flow structures for more comprehensive analyses.
Decision Supported

Risk Controlled
Non-representative models, insufficient data, weak validation, and over-interpretation.
Success Criteria

Full technical basis and contextOpen this section to read the complete source technical narrative.
The Hydrodynamic Module simulates variations in water levels and current circulation generated by multiple driving forces, including tides, wind, river discharge, and wave-induced radiation stress (stationary or quasi-stationary conditions). The model also incorporates key hydraulic parameters such as bed roughness (Manning's coefficient or Chezy coefficient) and eddy viscosity (flux-based or velocity-based formulations).
The Hydrodynamic Module can be applied to computational domains using either structured rectangular grids (single or multiple nested domains) or unstructured flexible meshes (finite-element grids). Simulations may be performed using two-dimensional (2D) models to represent horizontal hydrodynamic processes or three-dimensional (3D) models to simulate both horizontal and vertical flow structures for more comprehensive analyses.
The Hydrodynamic Module supports a wide range of scenario-based simulations for coastal and marine engineering, environmental assessment, and operational management, including the following applications.
