—In the present paper, a multi objective
optimization approach based in Genetic Algorithm, Design Of
Experiments and Response Surface Method strategies, is
applied in order to predict the optimal CFD model parameters,
allowing to model with high accuracy the 3D free surface flow of
urban flood propagation retaining the total computation time
(CPU-time) as short as possible. An experimental data set was
used in this study as a validation means for numerical optimized
models. We can say that the constraints in terms of computation
time and accuracy, related to the application of 3D CFD
modeling for flood propagation problems can be overcome by
making an optimal choice of the advanced parameters of model.
