Abstract. Although many studies have explored the effect of teleconnection indicators on flood, few investigations have focused on the assessment of the expected damages resulted by flood under the El-Niño or La-Niña condition. Therefore, this study’s aim was to determine the effect of El-Niño on the expected flood damage in the Kan River basin, Iran. To determine the flood damage costs, first, the precipitation enhancement during El-Niño condition was estimated then using a probabilistic approach the inundation area was determined under 5, 10 and 50 year return periods. The results showed that El-Niño increases the precipitation amount up to 8.2 % and 31 % with 60 % and 90 % confidence level, respectively. Flood damage assessment using damage-elevation curves showed that the expected increase percentile in flood damage for smaller return periods, which is more frequent, is much more than that for larger return periods. In general, for the return periods of 5- and 10-year, 31 % increase in the precipitation would result in 2416 % and 239 % damage increase, respectively. However, for the 50-year rainfall this increase amount will be about 74 %. These results indicate the importance of small flood events in flood management planning during El-Niño.

“…Nevertheless, study show that it was necessary to ensure that the assessment factors and weights fit the purpose of the project to be carried out. Zhou et al [11] analyzed whether the diversification of the measures has an impact on reducing flood damages Yazdi et al [12] applied an optimization method based on a simulation when selecting the measures for a basin, and the optimal size of the combination was calculated by applying the Pareto method to compose combinations. The research shows that economically efficient measures can be selected by using the proposed method.…”

Climate change and fast urbanization increased rainfall intensity and runoff discharge. These changes lead to the growing possibility of flood damages. In South Korea, a government established the “Comprehensive Flood Prevention Plan (CFPP)” for each of river basin against flood. The plan is based on the combination of structural measures selected by experienced hydrologists. However, it lacks clear criteria. To solving this problem, this study classifies the structural measures and suggests a combination method, which use relationships between measures, to ensure the objectivity of the process in identifying proper measures. For Anyangcheon river basin, two plans are provided; the first is developed by the study, and the other is by the CFPP. Comparing the two plans, the results show that the combination, selected by proposed method in this study, is economically more feasible compared to CFPP. Therefore, this study expected be useful when selecting and combining structural measures for formulating river basin flood prevention plans.

Yazdi et al (2013) obtained optimal prioritisation of watershed management for flood risk mitigation on a watershed scale. They used a mathematical model to minimise the flood damages and total costs of watershed management measures.…”

The management of urban run-off is considered a success when the issues of flood and pollution are properly addressed. Flood can be controlled by reduction of peak flows and by treating polluted run-off. Best management practices (BMPs) are important tools for reducing pollutants and run-offs. Location of BMPs is an important factor in determining their optimum arrangement. In this paper, based on simulation-optimisation model, a methodology has been proposed to select proper BMPs with optimum arrangements. Quality and quantity of water flow in urban area were modelled, using Storm Water Management Model. Multi objective particle swarm optimisation was also used to reach the BMP layouts so that the peak flow and pollutant concentration can be effectively minimised. The proposed methodology was developed for district number 10 of Tehran municipality. The results showed that the proposed methodology could lead to an improvement in quantity and quality of run-off. For example, different combination of 32 BMPs led to a decrease in peak flow for 2, 5 and 10-year return periods as much as 10%, 21%, and 13%, respectively, while the combination of 45 BMPs decreased the total suspended solids mean concentration for 2, 5 and 10-year return periods as much as 50%, 57%, and 59%, respectively.
