Narrow Results

The present paper shows results of the wave forces from the hydraulic model tests carried out in a big channel on a new design of concrete caisson to be used as vertical breakwater. This caisson has a rectangular inner "yard" much larger than the rest of cells located around it. This yard possesses, as main feature, the absence of foundation base to reduce the up-lift pressures, being able to be filled with a quarry stone or a dredging material. The usage of this dredging material could be considered an advantage for this new design of caisson from the environmental point of view. The caisson was subjected to four wave storms, each one with a different peak period, and several significant wave heights.
