2D hydrodynamic modelling using 'classic' grid

This two-day, hands-on course will teach you the fundamentals of 2D hydrodynamic modelling and give you an introduction on how to set up a hydrodynamic model using MIKE 21 Flow Model HD and MIKE 21 NHD (Nested) using rectangular grid bathymetry.

The MIKE 21 Flow Model HD module provides the basis for computations of processes performed in many other modules such as sediment and mud transport, transport of heat and suspended matter, oil spill, agent based modelling and ecology but can also be used as a stand-alone application. The module simulates unsteady flow taking into account bathymetry, sources and external forcing.

Typical application areas of MIKE 21 Flow Model HD include assessment of hydrographical conditions in nonstratified waters, coastal flooding and storm surge, inland flooding and overland flow, forecast and warning systems.


  • • Selection of geographical coordinate system and bathymetry digitisation (grid)
  • • Data organisation, import, editing and quality control
  • • Fundamentals of 2D flow modelling
  • • Setting up simple hydrodynamic models
  • • Managing boundary conditions
  • • Calibration and validation procedures
  • • Using the utility software of MIKE 21/3 Flow Models
  • • Analyses of model input and output
  • • Interpretation of results and visualisation, including video animation
  • • Hands-on exercises


Professionals in hydraulic engineering and management working with inland flooding, lakes, coastal areas or marine environment.

Some experience with hydraulic modelling would be an advantage.

This course constitutes a basic platform for further marine courses and activities.
