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.

Decision making under uncertainty for risk management of water supply projects
Author : ABBAS ROOZBAHANI
ABSTRACT
Safekeeping of drinking water supply systems needs risk mitigation options to decrease the vulnerability against natural
and manmade events which threaten the normal operation of these systems in meeting the water demands. Improper
selection and implementation the best option leads to increasing the water projects economic and social costs. For
proper decision making about possible risk reduction measures, an effective decision support tool is required with ability
of considering the different uncertainties related to input data such as criteria values and weights, risk assessment
procedure and decision makers with different idea and objectives. In this paper a hybrid decision making model has
been presented to rank the risk management scenarios in field of water supply infrastructures regarding the different
effective criteria and ranking methods in a group decision making space. To deal with the mentioned uncertainties and
reliable decision making, a probabilistic based model of Monte Carlo Simulation (MCS) has been combined with two
multi criteria decision making methods (MCDM) of PROMETHEE and TOPSIS to map a stochastic problem to so many
deterministic problems. A case study in Iran has been utilized to show the capabilities of the presented model for
prioritizing the urban water supply projects.
