The Kalypso project is modularly designed. Thus, simulation specific functions are bundled in so-called modules (e.g. Kalypso Hydrology, Kalypso 1D/2D, etc.) and basic functionalities such as GIS functions and time series analysis functions are combined in the KalypsoBASE framework.

New applications comprising a wide functional range - so-called "rich clients" - can be built on the basis of this framework.

Extensive applications in the fields of water resources management as well as nature and landscape protection have been developed based on this framework. This is impressively demonstrated by the following research and development projects.
