Kenadsa, a peaceable oasis in southwestern Algeria, with the discovery and exploitation of coal (1917-1956), underwent graft of Western models for its development.

Kenadsa, a peaceable oasis in southwestern Algeria, with the discovery and exploitation of coal (1917-1956), underwent graft of Western models for its development. That has cleared the oasis of the spatial dimension and transformed into a mining village by excellence. These networks of foggaras draining groundwater, enclosed in a multilayer aquifer, which becomes free on the northern border of the Ksar. There were 25 foggaras of sources (Ain), each of which had its own drainage channels to downstream gardens of Ksar. The distribution of water from these sources was ensured by a complex network, fed by drainage galleries that meander the alleys of Ksar and gives place to access points for domestic uses. The right to water is generally private property; one could dispose of according to modes of transmission of a property. It's sharing for irrigation is governed by the volume and time. Currently, only some ten foggaras of sources that are still alive (Ain Sidi Mbarek, Ain Dir, Belkaid Ain, Ain Sheikh ....). These waters are characterized by mediocre quality (pH 7.31, CE: 4.88 ms / cm, RS 2420 mg / l Ca ++: 288.2 mg / l, SO4--: 468 83 mg / l.).... view less

Kenadsa, oasis paisible dans le sud - ouest algérien, avec la découverte et l'exploitation du charbon (1917 à 1956), a subi la greffe des modèles o ccidentaux pour son développement. Ceci a oblitéré de son espace la dimension oasienne et s'est transformée en un village minier par excellence. Les réseaux de foggaras drainent les eaux souterraines, renfermées dans un aquifère multicouche, qui devient libre sur le liseré nord du Ksar. On comptait 25 sources et foggaras (Aïn), dont chacune possédait ses propres canaux de drainage vers les jardins en aval du ksar. La répartition de l'eau de ces sources était assurée par un réseau complexe, alimenté par des galeries drainantes qui serpentent les ruelles du Ksar et donne lieu à des points d'accès pour des utilisations domestiques. Le droit de l'eau est généralement propriété privée; on pouvait en disposer selon les modes de transmission d’un bien immobilier. Son partage pour l'irrigation est gouverné par le volume et le temps. Actuellement, seule une dizaine de foggaras de sources qui sont encore vivantes (Ain sidi Mbarek, Ain Dir, Ain Belkaid, Ain Cheikh....). Ces eaux se caractérisent par une qualité médiocr e (pH : 7.31, CE : 4.88 ms/cm, RS : 2420 mg/l, Ca++ : 288.2 mg/l, SO4 -- :468. 83 mg/l).... view less
