Conclusions

  1. 1.

    Optimization of the designs of hydraulic structures in general and of earth dams in particular becomes an inseparable part of designing, since it makes it possible to select the most economical design while fulfilling all technical specifications and opens the expanse for a technical and economic analysis.

  2. 2.

    Of the investigated methods (Pareto, penalty functions, and direct search), the most convenient is the direct search method, since it makes it possible to adhere to all constraints; but the other methods also have their positive properties, for example, the Pareto method makes possible a complex evaluation (although approximately) of the performance of the structure.

  3. 3.

    The use of optimization makes it possible to reduce the cost of the designs of earth dams by 5–15% and more in comparison with those being selected.
