MIKE 21 is the industry "gold standard" for coastal and estuarine hydraulic modeling. It is an incredibly powerful, robust suite of tools used by governments, large engineering consultancies, and research institutions worldwide. However, it comes with a steep learning curve and a high price tag, making it best suited for professional high-stakes projects rather than casual academic research. dhi mike 21
After over three decades of continuous development, remains a cornerstone of computational hydraulics. It is not the cheapest or the simplest model, but when you need defensible, accurate, and physically robust predictions of 2D water movement—from the Mekong Delta to the North Sea—MIKE 21 delivers.
For decades, the global engineering and scientific community has relied on DHI MIKE 21. Developed by DHI (Danish Hydraulic Institute), MIKE 21 is a comprehensive, advanced software suite designed for 2D free-surface flow modelling. It simulates physical processes in oceans, coastal waters, and estuaries, making it an indispensable tool for water resource management. What is MIKE 21?
DHI MIKE 21 is the global industry standard for modeling coastlines, seas, and shallow water environments. Developed by the Danish Hydraulic Institute (DHI), this software suite simulates physical processes in two dimensions (2D) across a horizontal plane. Engineers, researchers, and environmental consultants rely on it to solve complex hydraulic, coastal, and marine challenges. The Hydrodynamic module is the foundation of the
"Evacuate the secondary dock," Elias said, grabbing the phone to call the Port Master. "Secure the containers on rows C through F. We're looking at localized flooding of 40 centimeters within four hours."
Modules like ST (Sediment Transport) and LITPACK predict shoreline evolution and bed level changes. Comparative Strengths
MIKE 21 seamlessly couples with MIKE 3 (3D hydrodynamic modelling) and MIKE HYDRO River (1D river networks) for integrated catchment-to-sea simulations. Conclusion MIKE 21 Mooring Analysis | Vessel Response Simulation
