Water and energy fluxes at the surface-subsurface interface of the Orgeval , France

Abstract : Accurately quantifying surface-subsurface water and energy fluxes is challenging because a myriad of morphological and physical factors. The spatial and temporal variability of these factors and nested interfaces lead to patterns in residence time over multiple spatial scales. In these scope, we present here a new understanding of the stream-aquifer interface functioning. Our approach accounts for hydrology and thermal processes based on a combination of field methods and modelling tools. The concept of nested stream-aquifer interfaces is used to simulate the variation of the spatio-temporal surface-subsurface exchanges at the basin scale from LOcal MOnitoring Stations measurements of the stream-aquifer exchanges. This study was applied to the Orgeval basin over four years between 2012-2016. A fiber optic has been set up since 2016 along a 1 km river to improve our description of water and heat fluxes between the stream and the aquifers. This complementary monitoring allows to characterize Groundwater-Surface waters interactions at different spatial and temporal scales.
