Vienna Catchment Science Symposium 2025
Thema: Hydrological Scaling Revisited
12th Symposium | 3rd May, 2025
© Miriam Bertola
Hydrological observations and process studies are usually conducted at small spatial scales, while water management decisions, and the models that support them, are needed at larger, landscape scales.
The methodological challenge of bridging this scale gap has attracted a lot of research in the 1980s and 1990s, but has received less attention in recent years, even though the issue persists.
The aim of this symposium is to explore the conceptual foundations of the topic in light of recent advances in measurement and modelling approaches, and to identify potential directions for future research on addressing the scaling problem.

| Group 2: Framing the testing of scaling relationships Aim: to brainstorm the methods (data, models, frameworks) required to explore whether hydrological scaling relationships are suitable for transferring information across spatial scales.
