It accounts for wind shear stress, barometric pressure gradients, tidal forces, wave radiation stresses, and river inflows.
DHI Mike 21 builds upon the principles of Direct Hair Implantation (DHI), which involves the direct implantation of hair follicles into the scalp. The "Mike 21" refers to the proprietary device developed by Dr. Mike Kerry, designed to optimize the extraction and implantation process. This device features a specially designed needle that creates a micro-incision in the scalp, allowing for the precise placement of hair follicles.

MIKE 21 is a comprehensive software package designed to model physics-based processes in rivers, lakes, estuaries, bays, coastal areas, and seas. Unlike 1D models that simulate water moving in a single direction (like down a narrow pipe), MIKE 21 calculates water depth and horizontal velocity variations across a two-dimensional grid.
"It's the turbulence," Elias realized. "The default Smagorinsky formulation isn't catching the eddies off the pier. The water is tumbling too fast." He reached for the keyboard. "I need to switch to the K-Epsilon model for turbulence closure. It’s computationally expensive, but it’s the only way to get the final ten percent accuracy."
Modeling coastal storm surges, sea-level rise scenarios, tsunamis, and overland urban flooding caused by extreme rainfall events. It accounts for wind shear stress, barometric pressure
MIKE 21 is a professional engineering software package for simulating hydrodynamics, waves, sediment transport, and water quality in two dimensions. Unlike 1D models that simulate flow along a linear path, MIKE 21 solves the vertically integrated Saint-Venant equations (shallow water equations) across a continuous spatial grid. This allows users to capture lateral flow movements, eddy formations, and complex spatial variations in water levels and velocities.
At its core, MIKE 21 is a 2D modelling engine solving the incompressible Reynolds Averaged Navier-Stokes equations (RANS) using the depth-integrated approach (shallow water equations). It assumes that horizontal length scales are significantly larger than vertical scales, making it ideal for most coastal and fluvial environments.
Validated and used worldwide in critical coastal engineering projects. Mike Kerry, designed to optimize the extraction and
Outside, the first heavy drops of rain began to splatter against the reinforced glass of the operations center. The wind howled, rattling the frame. The real storm was here.
DHI Mike 21 has a range of modeling capabilities, including:
"Alright," Elias said, his jaw tight. "We strip the sediment. Focus purely on the HD—Hydrodynamics—and the SW—Spectral Waves. We run them coupled. I need to see the current interaction."
After calibration, validate with independent data (e.g., a different storm event). Then run scenarios: “design flood,” “future climate SLR +20cm,” or “new breakwater alignment.”
