Evaluation of adaptation options to flood risk in a probabilistic framework

It was found that increasing the height of the dikes would lead to smaller economic losses, while rebuilding with better materials would increase the average annual economic losses, but might decrease the risk of human casualties. Individual and combined impact of decision variables on flood risk were estimated for the city of Niamey. Quantitative tools were developed to help decision-makers and regulators choose the best preventive measures to mitigate flood risk.
