Quantification of high frequency stream-aquifer exchanges from the local to the watershed scale

Abstract : It is based on the implementation of a network of LOcal MOnitoring Stations (LOMOSs) within the sampling of the Avenelles experimental site (40 km 2 , GIS ORACLE). The LOMOS network has been developed within the framework of the ONEMA NAPROM project and the PIREN Seine research project. At each LOMOS, water pressure and temperature data have been monitored with a 15 min time step for 3 years. This unique dataset is used to analyze the variability of the interface hydrological functioning, as well as determine coupled hydrological-hydrogeological distributed model's parameters. The net water exchanged flux is lower than the real water flux flowing upwards and downwards of the interface. This illustrates the potential of the model to constrain geochemical processes occurring in the interface.
