ABSTRACT
ABSTRACT: When projecting and designing an embankment dam usually the cost of the spillway constructed as an independent body is high in comparison to the global cost of the dam. In some situations, special constraints forced to find innovative solutions to discharge floods maintaining the safety level of the dam. Molino de la Hoz and Llodio Dams are two examples of embankment dams with innovative solutions in this field. They were constructed in Spain in the seventies of the 20th century. This article describes these two case studies that were successfully implemented and have been operating correctly for the past forty years.
