Prevent before repair: What a new hydrology-based index reveals about river ecological status

When I first began analysing agricultural pressures in German river networks, I expected the familiar story of nutrient loads, pesticide traces and differences between landscapes. What I did not expect was how narrow the ecological safe operating space has become for many rivers. Even small increases in agricultural pressure, especially from pesticides, reduced the likelihood of achieving good ecological status in a clear and consistent way. Seeing this pattern emerge across so many catchments made me look more closely at …


Mathematical closed-form solutions in Geodynamics: insightful or detrimental?

Mathematics is certainly not every scientist’s cup of tea. Despite the latter, they are, for the most part, very important, since most problems, regardless of their complexity, start and end with a mathematical equation (or set of equations). In this week’s blog, Dimitrios Papadomarkakis (student at the National Technical University of Athens), discusses the subject of closed-form (analytical) solutions in Geodynamics. Specifically, the ever-lasting question on whether they are insightful or detrimental nowadays with the rapid development of Geodynamic numerical …


Last minute information for EGU26 abstract submission

If you have not yet submitted your abstract for this year’s General Assembly (GA2026), do not forget to submit as early as possible this week (instructions here), this avoids any last minute technical challenges. . You can submit only one abstract (except for invited speakers or if you submit to an EOS-session). For your hydrology-related research, the call-for-abstracts programme proposes the overwhelming choice of 165 sessions proposed by the ten subdivisions of the Hydrological Sciences division (HS) of EGU, 11 …
