A dataset on physico-chemical hyporheic variables in the Selune River: Towards understanding the impact of dam removal on riverbed clogging processes.

ABSTRACT: This article presents field measurements that document the physical and chemical response of riverbeds to critical hydrological and sedimentary forcing in the Selune River (France). The river flows into the bay of Mont Saint-Michel and thus impacts numerous economic activities and the spawning of several key species such as Atlantic salmon and lamprey. To restore the hydro-sedimentary continuity of the river, two dams are currently being removed. Significant changes in the stream flow regime, stream-aquifer exchanges and sediment transport are expected, hence the monitoring campaign. A network autonomous sensor (water level, temperature, conductivity, oxygen and pressure differential) was installed on 18 October 2021 at various depths in the riverbed and the river for a one-year period.
