Blanch, X., Guinau, M., Eltner, A., and Abellan, A. (2023): Fixed photogrammetric systems for natural hazard monitoring with high spatio-temporal resolution, Nat. Hazards Earth Syst. Sci. Discuss., https://doi.org/10.5194/nhess-23-3285-2023 In this publication we address the lack of technical expertise in the geoscience community in the design and construction of photogrammetric systems for monitoring natural hazards at high spatio-temporal resolution. Accordingly, we provide in-depth information on the components, assembly instructions, and programming codes required to build them, making… Read More

Frank, C., Rußwurm, M., Fluixa-Sanmartin, J., & Tuia, D. (2023). Short-term runoff forecasting in an alpine catchment with a long short-term memory neural network. Frontiers in Water, 5, 1126310. https://doi.org/10.3389/frwa.2023.1126310 The governing hydrological processes are expected to shift under climate change in the alpine regions of Switzerland. This raises the need for more adaptive and accurate methods to estimate river flow. In high-altitude catchments influenced by snow and glaciers, short-term flow forecasting is challenging, as the exact… Read More

Risk assessment approaches and decision-making strategies have traditionally assumed the stationarity of climatic conditions, including the persistence of historical patterns of natural variability and the likelihood of extreme events. However, climate… Read More
