III.2.3. MIKE HD
MIKE HD is an advanced hydrodynamic module that enables users to define initial and
boundary hydrographic conditions, incorporate bed resistance and wind forcing, and
accommodate various sources, sinks, and structures. It solves the Saint-Venant equations while
considering factors such as bottom friction, meteorological events, Coriolis force, turbulence
modeling, and temporal variations in domain geometry. The module accurately predicts water
flow patterns, velocities, and pressure distributions, and also calculates nearshore currents,
accounting for wave radiation stresses in the surf zone. MIKE HD's flexibility is enhanced by its
support for different grid types and its user-friendly interface. It seamlessly integrates with other
modules, providing hydrodynamic conditions for coupled modelling, and leverages efficient
parallelization techniques and high-performance computing resources. Overall, MIKE HD is a
comprehensive and powerful tool for modelling and analyzing hydrodynamic processes in
various marine and coastal applications.
The equation in shallow water is as follows
By merging the equation of horizontal momentum and the continuity equation for shallow water
depth (ℎ = í µí¼ + í µí±) where h represents the total water depth as the sum of the water level η and
the bottom elevation d within the Cartesian coordinate system, we arrive at the subsequent
equation:
Equation III-13
Equation III-14
