The Saoura Foggaras: Degradation of Hydraulic System Millennium Case of Beni Abbes, Ouakda, Beni Ounif and Lahmar (Algeria)

Abstract

In this article, we studied, for the first time, the foggaras of Saoura. Five missions were carried out in the oases of Kerzaz, Lahmar, Boukais, Beni Ounif, Ouakda, and Beni Abbes during the years 2009, 2010, 2011, 2012 and 2013. The first results showed that there was a difference between the foggaras of Touat and those of Saoura. The galleries of Saoura are much shorter than those of Touat and Gourara. On the contrary, the distribution of water from the Touat and Gourara foggaras is carried out per unit volume, whereas from the Saoura foggaras per unit time. The foggaras we visited are practically in a degraded condition. The contribution of modern technology (pumps and wells) in the oases of Saoura is the principal cause of the decline of the hydraulic system millennium.

The Sharing of Flood Waters in the Ksours of Ghardaia and Berriane (Algeria) Hydraulic Study

“…In the Saoura Valley, the oases are equipped with foggaras that capture the waters of the Grand Erg Occidental (Taghit oases), spring water or groundwater. This water is used and shared among farmers based on an hourly mode [2] [3]. For the foggaras used in the oases of Touat and Gourara to capture groundwater, oasis people use a volumetric sharing system.…”
