CRESS is an initiative of the Netherlands Ministry of Infrastructure and Envrionment, Delft University of Technology and UNESCO-IHE. CRESS has been produced by IKM Engineering BV whereby rule definitions have partly been made by Royal Haskoning.

CRESS has been made possible with the financial contributions of the  sponsors and co-sponsors.

Special thanks goes to the  contributors of the valuable content of CRESS.

CRESS provides a collection of small routines, each containing a formula, or group of formulae, important in coastal and river engineering. The input and output is highly standardized, and is both available in numerical and graphical form.

For a design several steps have to be taken. CRESS does not automatically transfer data from one step to the next one. In this case the user is forced to think about the input and all the intermediate results.

CRESS does not prevent the user to apply a formula outside its range of application. Often in engineering it is useful to do so, however it has to be done with great care.

Tendencies and sensitivities are very important. The graphical routines of CRESS are made in such a way, that the sensitivity of a given parameter can be shown easily in the diagram.

The available Help routines allow the user to find some background information on applied formula, but also lists of constants, which can be entered (for example the Manning coefficients).
