Cross section geometry The geometry of the cross section has a trapezoidal shape Geotechnical parametres For the section under consideration were used the geotechnical parameters of the geologic report. GRADIENT METHOD The viscous action of water causes a transfer of energy between the water and the ground: between two points with \u0394s distance apart along a stream line, in fact, there is a hydraulic head \u0394h. The corresponding force is called seepage force: when it increases above a certain value, it can cause the phenomenon of Piping which consists in the removal of soil granules and the consequent faster and faster seepage flow until the formation of real flow channels.

ANALYSIS SYSTEM) is the\u00a0software for the mechanical analysis of soil using finite elements method. The traditional methods of analysis based on the concept of _LIMIT EQUILIBRIUM (LEM)_ do not allow the determination of stresses and deformations in the analyzed volumes. These limitations have led to the need to integrate the conventional analysis with analysis based on numerical models. These methods use the numerical evaluation of the problem and do not require simplifications to the calculation.
