Probability of overflow and overtopping for dike-rings

The program DIJKRING enables the calculation of the probability of failure by overtopping or overflow for a dikering. The random variables are the river discharge Q, the wind direction R, the sea level H and the wind velocity V. The program is based on numerical integration. The models for local water level calculation, the wave run up and overtopping discharge are the same as in conventional design. This latter point is essential to have the program accepted as the standard. An important advantage of the dijkring-approach is that the safety of the total system is evaluated, where conventional design always focuses on the safety of a single section.
