2.1 Short description of the Technology

Definition of the Technology:

Protection contre les crues d'un terrain de cultures situé en bordure de l'Oued Outat par la construction d'un mur de soutènement en gabion avec l'appui de contreforts, renforcé par des traitements biologiques (fixation des berges par le biais des plantations).

2.2 Detailed description of the Technology

Description:

Les paysans de la vallée d’Oued Outat-Midelt ont construit un mur en gabion soutenu par des contreforts et renforcé par des traitements biologiques (plantations des peupliers et des roseaux). pour protéger les terrains des cultures et les infrastructures hydro agricoles (canaux d’irrigation) contre les eaux de crue, surtout lorsque l’oued s’éloigne de son cours normal.

Cette installation est une nouvelle pratique initiée par les agriculteurs de l’oued Outat (savoir- faire local) pour protéger leurs terres situées sur les berges d'Oued Outat.
Elle leur permet de cultiver des parcelles dans des zones exposées aux risques d’inondations à l'aide d’ aménagements adaptés et efficaces contre les effets destructeurs des crues torrentielles.

Le gabion analysé a une hauteur de 2 m, une profondeur de 0,50 m, une largeur de 1 m . Les contreforts ont une hauteur de 2 m, une largeur moyenne de 1 m et une longueur de 2 m.

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• through land users' innovation
• through projects/ external interventions

Comments (type of project, etc.):

L'aménagement d’un terrain de culture situé en bordure de l’Oued Outat. Il s’agit de la construction d’un mur de protection contre les crues (300 m3 de gabions) renforcé par les traitements biologiques (Fixation des berges par le biais des plantations), pour diminuer la largeur de la rivière.
En faite, l’augmentation de la vitesse creuse le lit de la rivière, ce qui assèche l’aquifère à long terme.
