Determination of the population settlements in ndjamena based on the analysis of the frequencies of the wind characteristics. Period from 1983/1984 to 2010

This work solves the problem of determination the population settlements in Ndjamena and surroundings on the basis of the time frequencies of the characteristics of wind registered in this area, i.e. direction and velocity of the wind. It clearly indicates that the safety zone for the population settlements is included between the NE and E directions, assuming that there is no factories and industries in other localities situated before this area. So, industries and factories should be built in the domain between SW-W directions. To preserve populations from danger, the next settlement points behind this industrialized zone should be chosen taking into account the velocity of wind.
