| Flood protection is one of the practical methods in damage reduction.
Although it not possible to be completely protected from flood disaster but
major part of damages can be reduced by mitigation plans. In this paper, the
optimum flood mitigation master plan is determined by economic evaluation in
trading off between the construction costs and expected value of damage
reduction as the benefits. Size of the certain mitigation alternative is also
be obtained by risk analysis by accepting possibility of flood overtopping.
Different flood mitigation alternatives are investigated from various aspects
in the Dez and Karun river floodplain areas as a case study in south west of
IRAN. The results show that detention dam and flood diversion are the best
alternatives of flood mitigation methods as well as enforcing the flood
control purpose of upstream multipurpose reservoirs. Dyke and levees are not
mostly justifiable because of negative impact on down stream by enhancing
routed flood peak discharge magnitude and flood damages as well. |
