The foundation of the system, the , simulates the water level and flow velocity, taking into account forces such as wind, atmospheric pressure, tides, and bathymetry. It is the engine that drives other modules. 2. MIKE 21 Spectral Wave (SW) Module
The DHI Mike 21 software boasts an impressive array of features that make it an indispensable tool for coastal engineers and researchers. Some of the key features include:
Essential for coastal engineers, this module calculates non-cohesive sediment transport (sand, gravel). It predicts:
MIKE 21 operates on two distinct spatial engines to discretize the water environment. Choosing the right engine impacts model accuracy and computational runtimes. 1. Classic Grid (MIKE 21) dhi mike 21
Calculates bed load and suspended load transport to simulate coastline evolution, beach nourishment lifetimes, and channel shoaling.
How does MIKE 21 compare to competitors like Delft3D (Deltares), TUFLOW (BMT), or HEC-RAS 2D (USACE)?
MIKE 21's efficacy is driven by its core features: The foundation of the system, the , simulates
MIKE 21 is modular. You typically start with the module, then add others:
MIKE 21 is not just a single program; it is a modular ecosystem. Users can combine the core hydrodynamic engine with specialized modules to address specific environmental and engineering problems. Hydrodynamics (HD)
Resolves surf zones, wave breaking, run-up on structures, and partial reflection. Sediment Transport (ST) MIKE 21 Spectral Wave (SW) Module The DHI
MIKE 21 is deployed across diverse sectors to safeguard coastal communities and optimize maritime economies. Coastal Engineering and Infrastructure Design
Maintaining deep navigation channels is a multi-million-dollar challenge for global ports. MIKE 21 helps quantify sedimentation rates within channels, allowing port authorities to optimize capital and maintenance dredging schedules. Environmental Impact Assessments (EIA)
