Implementation of WSC techniques

The techniques implemented are:

• The gullies treatment: although limited in space, gully erosion removes and transports large volumes of material, and the risks it creates to the stability of the slopes located upstream are very high. The selection of species best adapted to this environment is very important and the decision to plant Atriplex halimus. The technology implementation in the gullied area in Hannanet is by strips (with a distance of 6m) to stabilize the gully, and stop the movement of the soil.
• The mulch: The technique consists of mulch covering the soil with a protective layer as uniform as possible to protect against the wind and prevent the direct effect of first rain on the floor. Keeping as much as possible the crop residue on the soil, improve several soil properties (regeneration of organic matter, infiltration and water conservation, aggregation of particles), also content of nutrients (nitrogen, phosphorus, potassium) and limit the impact force of the first drops of rain. This method has been applied in two plots, the first at MATLEG and the other in HANANNAT.

The team equipped a small catchment with a V‐notch, in order to obtain a general overview of the functioning at this scale. The layout of the catchment is as follows:

Discharge measurement occurs with a V‐notch and a limnigraph (pressure sensor), with the constraint of sediment accumulation behind the channel, during flood events.
