Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights roundup. For September, the Divisions we are featuring are: Climate: Past, Present & Future (CL), Earth and Space Science Informatics (ESSI) and Hydrological Sciences (HS). They are served by the journals: Climate of the Past (CP), Earth System Dynamics (ESD), Geoscientific Instrumentation, Methods and Data Systems (GI), Geoscientific Model Development (GMD), Hydrology and Earth System Sciences (HESS), SOIL, and Weather and Climate Dynamics (WCD).
Featured highlights
Hydrology and Earth System Sciences:
Calibration of groundwater seepage against the spatial distribution of the stream network to assess catchment-scale hydraulic properties – 6 September 2023
We propose a model calibration method constraining groundwater seepage in the hydrographic network. The method assesses the hydraulic properties of aquifers in regions where perennial streams are directly fed by groundwater. The estimated hydraulic conductivity appear to be highly sensitive to the spatial extent and density of streams. Such an approach improving subsurface characterization from surface information is particularly interesting for ungauged basins.
