The decision making in construction of earth dams is made in an empirical way, taking into account previous projects and the experience of involved engineers. We present in this article a modeling process with the objective of giving support to decisions making in the construction of earth dams with homogeneous and zoned sections. The modeling process is based on a multicriteria model, using the ZAPROS III method that allows determining the best selection of materials and on mixed integer nonlinear programming models that optimize the construction costs. A case study was applied in the project of the dam Frios. (Brazil, CE).
