Dhi Mike 21

DHI Mike 21 is a hydrodynamic modeling software that uses a finite difference approach to solve the shallow water equations, which describe the motion of water in rivers, estuaries, and coastal areas. The software is designed to simulate a wide range of water-related phenomena, including tidal and ocean currents, waves, water levels, and sediment transport.

If you are looking to run specific types of analyses like wave modeling or flood simulations, knowing the or type of water body would allow me to suggest which specific MIKE 21 module would be most suitable. Share public link

A third-generation wind-wave model, the SW module calculates the growth, decay, and transformation of waves, which is vital for designing offshore structures and analyzing coastal erosion [5.3].

The versatility of MIKE 21 has made it an industry standard across the globe. In , it is used to design offshore wind farms by modeling wave-structure interactions and seabed scour. In flood risk management , city planners use MIKE 21 to create detailed flood inundation maps, assess the effectiveness of levees and flood walls, and design stormwater drainage systems for extreme rainfall events. For environmental management , regulators employ the software to set safe discharge limits for industrial effluents into rivers, ensuring that pollutant plumes do not exceed water quality standards in sensitive habitats. A notable example includes studies of the Venice Lagoon, where MIKE 21 has been used to manage tidal flow and evaluate the impact of mobile flood barriers (MOSE). Similarly, it has been applied to the Great Barrier Reef catchment to model the transport of sediment and nutrients from rivers to the reef ecosystem. DHI Mike 21 is a hydrodynamic modeling software

MIKE 21 operates on a two-dimensional, depth-averaged numerical framework. It solves the Reynolds-averaged Navier-Stokes (RANS) equations to compute water levels and velocities. Users can choose between two distinct grid types based on project requirements: Rectangular Grid (Classic)

Prior to constructing offshore wind farms, desalination plants, or wastewater outfalls, developers must assess their environmental footprint. MIKE 21 simulates thermal plumes from power plants, brine dispersion from desalination facilities, and the dispersion of treated wastewater to ensure compliance with strict environmental regulations.

MIKE 21 is a professional engineering software package developed by DHI used to simulate in a wide range of water bodies, including rivers, lakes, estuaries, bays, coastal areas, and oceans. While DHI offers other specialized modeling systems like MIKE 11 for 1D river flows and MIKE SHE for fully integrated surface and groundwater hydrology, MIKE 21 fills the crucial role of 2D and quasi-3D simulations , providing a detailed, spatially-distributed understanding of water processes.

Some of the key features of Mike 21 include:
