The hydrodynamic module in MIKE 3 solves the equations for the conservation of mass and momentum as well as for salinity and temperature in response to a variety of forcing functions and thus, an indispensable basis for most applications.
MIKE 3 HD simulates the water level variation and current velocities in response to a variety of forcing functions in lakes, estuaries, bays and coastal areas. The water levels and currents are resolved on either a rectilinear grid, a curvilinear grid, a triangular element mesh or any combination hereof covering the area of interest.
MIKE 3 HD includes formulations for the effects of:
- convective and cross momentum
- bottom shear stress
- wind shear stress at the surface
- barometric pressure gradients
- Coriolis forces
- momentum dispersion (through e.g. the k-e model or Smagorinsky formulation)
- density effects
- sources and sinks (mass and momentum)
- evaporation and precipitation
- flooding and drying
- hydraulic structures
Hydrographic boundary conditions can be specified as a constant or variable (in time and space) level or velocities at each open model boundary, as a constant or variable source or sink anywhere within the model, and as an initial free surface level map applied over the entire model.
MIKE 3 includes a wide range of hydraulic phenomena in the simulations and it can be used for almost any 3D application. It is particularly suitable for studying phenomena like
- tidal flows
- storm surges
- wave-driven flows
- oceanographic circulations
- density-driven flows
