The „Coupled surface to deep Earth processes: Perspectives from TOPO-EUROPE with an emphasis on climate- and energy-related societal challenges” international workshop was held between 28-29 September 2023 in the Institute of Earth Physics and Space Science in Sopron, Hungary. TOPO-EUROPE is a European multidisciplinary program launched by the International Lithosphere Program (ILP) in 2005 under the leadership of Sierd Cloetingh. The program represents a bottom-up, community effort to better understand and quantify the evolution of topography, the accompanying changes in sea level and their surface and deep Earth driving mechanisms. The workshop was opened by Balázs Gulyás, chair of the Hungarian Research Network (HUN-REN) (former Eötvös Loránd Research Network), then newest results of the TOPO-EUROPE participants were presented by researches of several European universities and research institutes. Subsequently, introduction of the workshop participants, and deliberation and planning of joint researches and tendering opportunities proceeded in roundtable discussions. Judit Mádl-Szőnyi and Brigitta Czauner from the József and Erzsébet Tóth Endowed Hydrogeology Chair and the RRf ÉMNL 5A subproject drew attention successfully by a poster (tilted as “Topography induced shallow terrestrial water cycle: environmental and geological consequences”) and in the roundtable discussions to groundwater and its numerous relationships to the geological topics of the workshop which were neglected by TOPO-EUROPE till now.
Participation in the event was supported by the National Multidisciplinary Laboratory for Climate Change project RRF-2.3.1-21-2022-00014.
