The main crop is the vine. The site is strongly anthropised (network of ditches, terraced slopes, etc.). The climate is sub-humid Mediterranean with a prolonged dry season. The average annual rainfall is around 650 mm and the average annual ETP (Penman) is 1090 mm. The basic hydro-meteorological equipment, in place since May 1992, consists of a network of 9 rain gauges and 4 pluviographs, a device for measuring water table heights (14 sites), a device for measuring flows, suspended matter and pesticides at the outlets of the catchment area and of two plots with different cultivation routes and a network of 8 stations for measuring soil water content and water potential. Roujan was part of the reference catchment area network of the Network Observation Service Used for Hydrology Research created by the GIP Hydrosystème.

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.

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.
-
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.
-
Evaluation of pesticides contents in cultivated soils in the Roujan catchment area.
-
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.
