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

The rainfall of the Roujan (Hérault) catchment area has been acquired since 1992 through various measuring points on which sensors are positioned on a long-term and continuous basis. The data from these sensors are directly recorded on servers in Montpellier through remote transmission. Verification treatments and possible corrections are applied before the data sets are integrated into the HYSAE database. Through the OMERE data portal accessible from this sheet, the data can be downloaded from an interactive map. In addition to these raw data rainfall records, a so-called "synthetic" time serie is elaborated to provide a complete and uninterrupted chronicle of rainfall data representative for the catchment area.

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.

Runoff and stream flow discharge monitoring in the Roujan catchment area (Hérault) is operational since 1992 at catchment and sub-catchments hydrological stations on which automatic sensors records water level time series on a long-term and continuous basis. The data from these sensors are collected and instantaneously transmitted to servers in Montpellier. Verification and correction processes on the raw data, as well as the generation of elaborated data (e.g. calculation of flows from water heights or modification of time steps) are applied before integration of the data sets into the HYSAE database. The water level and discharge time series can be downloaded from an interactive map through the OMERE data portal accessible from this page.

A flow tower is installed on the watershed of Roujan as well as a meteorological station of the AgroClim service unit (INRAE). At these points a set of sensors are arranged in order to collect various meteorological variables such as wind speed, air humidity and temperature, global radiation or evapotranspiration. Just like the other measurements made on the basin by sensors, data acquisition units record the values which are transmitted several times a day to our servers at the INRAE centre in Montpellier or retrieved via Agroclim's webservice. R routines are then used to process these data and prepare them for integration into the HYSAE database of the LISAH, thus integrating them into the information system for OMERE. Through the OMERE data web portal, the address of which is given in this fact sheet, the data can be consulted and downloaded.

Runoff and stream flow discharge have been monitored since 1994 at the outlet of the Kamech catchment, and since 2005 at four sub-catchment hydrological stations. Automatic sensors continuously collected and transmitted water level time series to servers in Montpellier (France). Verification and correction processes on the raw data, as well as the generation of elaborated data (e.g. calculation of runoff, discharge from water levels, modification of time steps, etc) are applied before integration of the data sets into the HYSAE database. The time series can be downloaded from an interactive map through the OMERE data portal accessible from this page.

The Kamech basin is located north of Cap-Bon, in the governorate of Nabeul, on the border between the sub-humid and semi-arid Mediterranean climates. The average inter-annual rainfall is about 640 mm and the potential evapotranspiration is 1300 mm. The outlet of the basin is occupied by a hilly lake built in 1994 (140,000 m3 of initial capacity). The inter-annual flow coefficient is of the order of 10%-15% and the erosion of 15 t/ha/year. Land use is characterised by a cultivation rate close to 75% with, in order of importance: cereals, legumes and irrigated market gardening. This basin has been the subject of a monitoring of anthropogenic activities (land use and management, agricultural practices...), of agro-climatic variables, and of runoff and erosion since 1994 (+ pesticides more recently) at its outlet and since 2005 on 4 substations. This watershed is part of a network of 27 watersheds monitored under an agreement with the Tunisian Ministry of Agriculture (DGACTA).
