The evolution the speed of wind according to time is modelized by a function analytical or generated by a statistical law starting the data of measurement for a given site. In a context of theoretical modeling, the profile of wind must satisfy two criteria:

1) The duration of the profile must be limited to reduce the time of simulation

2) The profile of the wind must be representative of the characteristics of the deposit (intensity, variability, statistical distribution…).

In this study, we represented the evolution the speed of the wind, by a scalar function which evolves/moves in time, modelized in deterministic form by a sum of several harmonics. Profile of the wind simulated with a mean velocity of 8.2m/s.-The evolution the speed of wind according to time is modelized by a function analytical or generated by a statistical law starting　the data of measurement for a given site.
