OUED M’ZAB'S I.R.S DEVELOPMENT POPULATION AND FLOOD, LIFE IN HARMONY PART 3: THE GENIUS OF FLOODWATER SHARING
This paper evokes for the first time, flood management in the Ghardaïa oasis for more than 7 centuries. For this purpose, a hydraulic millennium development was realized by the Mozabites on the M’zab River. During the period: 1996-2020 we carried out several missions at the rate of two to three per year. Investigations and inquiries were carried out with the Ksourian population and the Oumana El Ma (water management committee). The M’zab River was laid out in three ways, which is the originality of the IRS Development. This gives priority to irrigation followed by recharging of the water table and the security of the oasis. This study shows that the IRS Development contains two seguias intended for irrigation. It is the seguia of Bouchemdjane to irrigate the upper part of the palm grove - East of Ghardaïa. The Tardja N’Takdimt is intended for the irrigation of the lower part of the palm grove - East of Ghardaïa.
