MIKE 21 Curvilinear Flow Model

Conduct advanced studies of river dynamics, focusing on sediment transport and morphology


MIKE 21 Curvilinear Flow Model (MIKE 21C) is powerful river morphology modelling software designed to transform complex river dynamics into comprehensive, actionable insights for teams and organizations. By integrating modules for hydrodynamics and sediment transport, this software ensures a holistic approach to river studies, supporting your decisions with accurate data on scour, deposition, and bank erosion.


Perfect for river engineers, environmental consultants, and flood risk managers, MIKE 21C includes features designed to predict changes over various time scales. By also accommodating complex sediment mixes, MIKE 21C helps you design safer, more efficient waterways.
