In this paper we discuss on the necessity of applying data mining operators on information systems containing a set of variables which describe the characteristics and behaviors of a specific system and could be exploited in approximating system’s functionality. For the problem of function approximation, we developed a new approach combining two intelligent methods. At first we used an algorith...

From the numerical point of view, the complexity of the fluid dynamic processes involved has so far hindered the direct application of Navier-Stokes equations within the armour blocks, due to the complex geometry and the presence of strongly non stationary flows, free boundaries and turbulence. In the present work the most recent CFD technology is used to provide a new and more reliable approac...

Abstract This study develops a new numerical simulation model for rubble mound failure prediction caused by piping destruction under seepage flows. The has been pointed out as significant cause of breakwater during tsunamis. Once boiling and heaving occur on the surface, suddenly propagates in opposite direction flow. For prediction, coupled fluid-soil-structure simulator is developed combining...

Abstract Caisson type gravity quay wall is a common structure used in the coastal regions. However, many of existing walls constructed past are becoming obsolete. Therefore, main goal this study to enhance performance these by increasing front water depth. To deepen depth, special grout ejected solidify rubble mound under caisson toe, then excavating part placed designed level. Various cases wi...

Probabilistic and deterministic analyses are implemented for the armor units of rubble foundation mound composite breakwaters which is needed to protect upright section against scour mounds. By a little modification incorporation previous empirical formulas that has commonly been applied design mound, new type formula stability number suggested capable taking into account slopes mounds, damage ...
