An underground view of surface hydrology: what can piezometers tell us about river floods and droughts?

Abstract

An underground view of surface hydrology: what can piezometers tell us about river floods and droughts?Une vision souterraine de l'hydrologie de surface : que nous disent les piézomètres des crues et des étiages ?

A hydrogeological acrostic: in honour of Ghislain de Marsily

“…In order to better understand how aquifers and rivers interact during extreme events, Pelletier and Andréassian [2023] study how yearly extremes of groundwater level and streamflow time series are related, using a large set of catchments and piezometers: the result is an aquifer typology, which distinguishes between aquifers that demonstrate correlations between groundwater level and streamflows only with high-flow events, only with low flows, with both types of events or with none of them.…”
