Modules like ST (Sediment Transport) and LITPACK predict shoreline evolution and bed level changes. Comparative Strengths
Simulates the growth, decay, and transformation of wind-generated waves and swells in offshore and coastal areas.
The "21" signifies its 2D nature (two horizontal dimensions), allowing it to model complex, unsteady flows in rivers, lakes, and oceans. Core Modules of MIKE 21
Thousands of peer-reviewed papers (like those found in MDPI Water ) rely on MIKE 21, providing users with high confidence in the accuracy of their results. Pro Tips for New Users dhi mike 21
The software's world-class reputation stems from its ability to provide a for projects ranging from small-scale urban drainage studies to large-scale oceanographic analyses. By combining an advanced graphical user interface with a highly efficient and reliable calculation engine, MIKE 21 has become an indispensable tool for hydrological and maritime engineers worldwide.
Waves are primary drivers of coastal erosion and structural loading. MIKE 21 offers several wave modules:
Developed by (Danish Hydraulic Institute), MIKE 21 is a comprehensive modeling system for 2D free-surface flows. It is primarily used for: Modules like ST (Sediment Transport) and LITPACK predict
Industrial projects near the coast—such as power plant cooling water intakes, desalination outfalls, and offshore wind farms—require strict environmental clearance. MIKE 21 simulates thermal plumes and brine dispersion to ensure compliance with mixing zone regulations. Advantages of Using MIKE 21
Coastal environments, estuaries, and inland waters are dynamic systems driven by complex physical forces. Managing these environments requires precise predictive capabilities to mitigate flood risks, design resilient marine infrastructure, and understand environmental impacts.
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.

Divided into cohesive (mud) and non-cohesive (sand) transport modules, this tool predicts morphological changes over time.
The MIKE Zero shell provides a unified graphical user interface for data preparation, mesh generation, simulation execution, and post-processing visualization.
The user interface of DHI Mike 21 is user-friendly and intuitive, with a range of tools and features, including:
Calculates bed load and suspended load transport to simulate coastline evolution, beach nourishment lifetimes, and channel shoaling.
