OUED M’ZAB'S I.R.S DEVELOPMENT POPULATION AND FLOODS, LIFE IN HARMONY PART 1: HYDRAULIC STRUCTURES

This paper evokes for the first time, an ancestral hydraulic development that has been implemented for more than 7 centuries in the M’zab valley. We baptized: "IRS development". To understand the role of existing millennia structure in the Rivers of M’zab area was conducted during the period: 1996-2020, several missions at two to three per year. Investigations and inquiries were carried out with the Ksourian population and the Oumana El Ma (Management Committee). It turns out that the IRS development of M’zab River is the largest development in the entire M’zab Valley. About 18 structures between galleries, spillways, canal, dam and well were completed. In addition, 2 control towers and 8 operating chambers have been built along the M’zab River to monitor floods and watershed operations. This demonstrates the greatness of the project and the genius of the Mozabite.
