OMIV - Time series of hydrochemical parameters on landslides
Since 2010, the monitoring network, set up within the framework of the SNO- (Multidisciplinary Observatory of Slope Instabilities). This monitoring network provides a large amount of hydrogeological data The hydrogeological monitoring is composed of a high frequency and quasi-continuous monitoring, ...
OMIV - Time series of meteorological parameters on landslides
Meteorological observations acquired on OMIV landslides using a standardized protocol (6min, 15 min, 30 min, 60 min) according to the measured parameters and transfered in a Ascii standardized file format with the file database management system BD-OH OMIV. Estimation of potential evapotranspiration ...
OMIV - Time series of electrical resistivity data recorded on landslides
Time series of electrical resistivity data acquired on OMIV landslides at a daily or sub-daily frequency depending on the sites and observation periods. The data are acquired at the surface through electrical panels or at depths in boreholes. For the electrical panels, the resistivity data are ...
