, waves, sediment transport, and water quality in environments like rivers, estuaries, and coastal waters. Core Capabilities and Functionality

The Flexible Mesh (FM) engine uses an unstructured grid made of triangles or quadrilaterals of varying sizes. This allows users to increase resolution in critical areas—like narrow channels or around port structures—while keeping a coarse resolution in the open sea. It optimizes computational efficiency while precisely mapping complex geometries. Key Modules of MIKE 21

is a premier software suite developed by the Danish Hydraulic Institute (DHI) for two-dimensional (2D) simulation of physical processes in coastal, marine, and river environments. Widely recognized by engineers and scientists, it is used to model everything from water levels and tidal currents to sediment transport and water quality. Core Capabilities and Modular Design dhi mike 21

The software relies on the numerical solution of two-dimensional shallow water equations (the Reynolds-averaged Navier-Stokes equations). It factors in critical physical parameters such as: Bottom friction and bathymetry (underwater topography) Wind shear stress and atmospheric pressure variations Wave radiation stresses Coriolis force (earth's rotation effects)

Major projects (e.g., Palm Jumeirah in Dubai, land reclamation in Singapore) used MIKE 21 to predict how dredged plumes disperse and settle, minimizing environmental damage to seagrass and coral. , waves, sediment transport, and water quality in

MIKE 21 is not a single program but a suite of modules. The strength lies in how these modules couple together.

"Overtopping starts at Hour 14," Elias calculated. "Maximum inundation at Hour 16. The port is currently planning for a 1.2-meter surge. This model is showing 1.8."
