The groundwater temperature is measured at different points in the Roujan catchment. In Roujan site, the groundwater is shallow with a free surface water table rising and falling in the soil and subsoil layers. The measurements are made at different points in the catchment with piezometers. A piezometer is a perforated PVC tube at its base installed in the soil through a borehole. In every piezometer, the groundwater temperature is monitored at high frequency (~15') with autonomous and automatic temperature probe integrating acquisition units. Through the OMERE data portal accessible from this website, the data can be downloaded from an interactive map.

Water sampling in rain, runoff and undergroundwater are performed on the fields and send to a specialized laboratory to quantify major elements contents (Ca, Mg, Na, K, SO4, PO4, HCO3, NO3) ( FILTRATION ???. PH ??? ? EC, ???)

The physico-chemical parameters measured in the Kamech basin and accessible via the data portal concern the electrical conductivity of the water.

These data correspond to a non-systematic monitoring of dissolved, particulate or total organic carbon contents in water (rain, surface overflow, underground water) in the Roujan catchment area.

The water table depth from the soil surface is measured at different points in the Kamech catchment. In Kamech site, the groundwater is shallow with a free surface water table rising and falling in the soil and subsoil layers. The measurements are made at different points in the catchment with piezometers. A piezometer is a perforated PVC tube at its base installed in the soil through a borehole. In every piezometer, the water table depth is measured by manual piezometric probe or monitored at high frequency (~15') with autonomous and automatic probe integrating acquisition units. Through the OMERE data portal accessible from this website, the data can be downloaded from an interactive map.

The evaluation of soil moisture in different areas of the Roujan catchment area is carried out by measuring the moisture content of fresh soil samples.

Soil moisture assessment in different areas of the Kamech catchment area is carried out using soil tensiometry measurements carried out on different areas and at different depths of the Kamech site.
