Metaheuristics in Flood Disaster Management and Risk Assessment

A conceptual area is divided into units or barangays, each was allowed to evolve under a physical constraint. A risk assessment method is then used to identify the flood risk in each community using the following risk factors: the area's urbanized area ratio, literacy rate, mortality rate, poverty incidence, radio/TV penetration, and state of structural and non-structural measures. Vulnerability is defined as a weighted-sum of these components. A „penalty‟ was imposed for reduced vulnerability. Optimization comparison was done with MatLab‟s Genetic Algorithms and Simulated Annealing; Results showed „extreme‟ solutions and realistic designs, for simulated annealing and genetic algorithm, respectively.
