DHI and its partners offer numerous ways to learn MIKE 21:
Running simulation...
The power and versatility of MIKE 21 mean it is deployed on thousands of critical projects around the world. Its ability to provide accurate, actionable data makes it essential for a wide range of engineering, environmental, and planning challenges.

is a powerful, comprehensive software package used worldwide for 2D modeling of hydraulics, water quality, and sediment transport in coastal and marine environments [5.2, 5.3]. Developed by DHI , a leading expert in water environments, MIKE 21 provides engineering solutions for offshore structures, port design, flood analysis, and environmental impact assessments [5.3]. dhi mike 21
A recent study in , used MIKE 21 to analyze how pollutants from different rivers disperse along the coast. The model revealed that pollutants spread fastest in three estuarine areas but were trapped within Yueqing Bay, demonstrating how MIKE 21 can provide crucial spatial insights for coastal environmental management.
The software features an intuitive Graphical User Interface (GUI) for mesh generation, boundary condition setup, and post-processing visualization.
When rivers overtop their banks or storm surges breach coastal defenses, MIKE 21 simulates the overland flow path. It generates high-resolution flood hazard maps, detailing inundation depth and flow velocity, which are critical for urban planning and emergency evacuation strategies.

The software's mathematical foundations have been rigorously peer-reviewed, tested, and validated against thousands of real-world laboratory and field datasets over several decades.
