IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Reliability - Based Upgrading of a Rubble Mound Breakwater in a Changing Climate
Author : Panagiota Galiatsatou and Panayotis Prinos
The present work aims at presenting an approach for implementing appropriate mitigation measures for upgrading of rubble-mound breakwaters to face the increasing marine hazards and the increasing exposure to downtime risks, based on reliability analysis of the studied structure coupled with economic optimization techniques. The approach includes the construction of probability distribution functions for all the stochastic variables of the marine climate for present and future conditions, the suggestion of different mitigation options for upgrading, the construction of a fault tree providing a logical succession of all events that lead to port downtime for each alternative mitigation option and the testing of a large number of possible alternative geometries for each option. From the total sample of acceptable geometries for each upgrading option, a single solution is selected minimizing the total costs of protection. The methodology is applied to a simplified form of the rubble-mound breakwater of the port of Deauville, in France. For the studied breakwater, the construction of a berm in front of the existing structure seems to be advantageous in terms of optimized total costs compared to the other mitigation options.
