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.

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 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.

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.

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 measurement of rainfall in Kamech catchment (Cap Bon/Tunisia) is operational since 1994 through a network of daily and instantaneous (tipping bucket) rain gauges, some of them being remotely connected to servers in Montpellier. Verification treatments and possible corrections aare applied before the data sets are integrated into the HYSAE database. A "synthetic" rainfall dataset derived from these measurements and accessible from the OMERE data portal is elaborated as a complete and uninterrupted chronicle of rainfall data for the catchment area.

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, ???)
