IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

OVERTOPPING PREDICTION OF CUBE AND CUBIPOD ARMORED BREAKWATERS USING THE CLASH NEURAL NETWORK
Author : JORGE MOLINES , GLORIA ARGENTE , MARIA P. HERRERA & JOSEP R. MEDINA
Overtopping estimation on mound breakwaters depends on climatic and geometrical variables. The roughness factor (? ) f is commonly used in overtopping estimators to take into account the armor unit shape, placement, number of layers and permeability. Usually, the ? given in the literature is associated with the armor unit type and number of layers. In this f study, the ? is considered a coefficient to be calibrated and dependent as well on the database used for calibration and f the overtopping estimator. The CLASH Neural Network (CLNN) and small-scale tests carried out at the Universitat Polit?cnica de Val?ncia are used here to obtain the roughness factor which minimizes the prediction error of double-layer cube armors and single- and double-layer Cubipod armors. The CLNN minimizes the prediction error when using ? [cubes 2Layers randomly-placed] = 0.54; ? [Cubipod 1Layer] = f f 0.48 and ? [Cubipod 2Layers] = 0.45, all of these slightly different from the ? values given in the literature. Overtopping f f discharge of double-layer cube armored mound breakwaters is higher than the discharge of single- and double-layer Cubipod armors.
