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.

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

The monitoring of suspended sediment loads in runoff and stream flows aims to quantify the amount of sediments translocated during runoff events. These measurements contribute to the understanding and the quantification of the soil redistribution induced by water erosion processes. The measurements of suspended matter are made through manual and automated water sampling at the hydrological stations, which are then processed and analysed in the laboratory to derive suspended sediment concentrations. A turbidimeter has been recently installed to complete the time series of sediment discharge. Suspended sediment concentrations are integrated into the HYSAE database, they can subsequently be consulted and downloaded via the OMERE data portal.

Pesticide contents are determined on the suspended matter extracted by filtration (0,7µm) in runoff water. Contents allow quantification of particula transport of pesticides and allow too compare it to solute transport.

water samples ( rain, runoff, underground water) are carried in icebox and frozen. ( FILTRATION ? ). Samples are analyzed by a dedicated laboratory, that quantify a set of parameters including from 1 to 430 pesticide active ingredients and their metabolites.

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 thematic map provided allows you to visualise the measurement points concerning this data acquisition device. This map is accessible via a standardised WMS flow, but also enables the data sets associated with the measurement point to be downloaded, depending on the case, via the ORE OMERE data portal.
