Description of the SLM Technology
Short description of the Technology
use the stones to build walls around agricultural terraces to protect them from erosion and make outlets (Spillway) to discharge excess water and prevent the destruction of the stands
Detailed description of the Technology
Is a structural one of the types of measures and that is where build walls around the land of stones available in the area to protect agricultural terraces from erosion as a result of the speed of the water flow.
This process starts of building walls to collect stones available and building walls around the agricultural terraces, which is beside the waterway and then land agricultural away from the stream where are building walls around land terraces threatened drift ranges wall height 2-3 meters and a width of 30 cm and is accompanied by building outlets with the construction of the walls. Different view slot spillway and the number depending on the amount of water entering the agricultural land terraces which is used irrigation number of agricultural terraces about 4 - 5 terraces (pieces) where irrigation start from the top-down system of first come through outlets which works to protect the land from erosion and destruction by water pressure due process flood irrigation .
walls and outlets Were built by hands where the process of building need a long time, the walls are built gradually according to the height of the surface of the soil where you are collecting sediment , which requires him to do to raise the walls and well outlets .
The implementation of this technique in filled valleys on the slope moderate 5% of the irrigation system mixed and used to irrigate crop of grapes , mainly for the purpose of self-sufficiency and to go to the market to trade, is the technology of long-term investments that need to be high costs in the process of starch and because of the natural conditions of flow velocity and the output from a pool of water in the mountain slopes , the process of maintenance necessary to sustain and maintain the technology .
