Abstract. We present CAMELS-CH (Catchment Attributes and MEteorology for Large-sample Studies – Switzerland), a large-sample hydro-meteorological data set hydrologic Switzerland in central Europe. This domain covers 331 basins within neighboring countries. About one-third of the catchments are located Austria, France, Germany Italy. As an Alpine country, vast diversity landscapes, including mountainous environments, karstic regions, several strongly cultivated along with wide range...
Abstract. In this study, we analyze how precipitation, antecedent conditions, and their spatial patterns interactions lead to extreme floods in a large catchment. The analysis is based on 10 000 years of continuous simulations from hydro-meteorological modelling chain for catchment, the Aare River basin, Switzerland. To account different flood-generating processes, our work with hourly time resolution. consisted stochastic weather generator (GWEX), bucket-type hydrological model (HBV),...
The cryosphere in mountain areas serves as a critical water resource, supplying melt to downstream communities spring well summer months for irrigation and human consumption. Effects of climate warming on the therefore availability are expected be substantial many ranges worldwide. An accurate representation glacier processes is thus crucial predict future catchments that currently at least partially glacier-covered. Hydrological models often focus meltwater-streamflow transformation...
The past few years have seen increasingly frequent and intense floods, culminating in 2024 with a year characterized by widespread devastating inundations worldwide. In Europe despite major advancements flood forecasting protection measures undertaken the past, in2024 heavy rainfall events resulted severe impacts massive socio-economic losses, claiming over three hundred lives. Extreme precipitation, breaking observed records, is expected to an increased likelihood under global warming all...
Dealing with large uncertainties associated estimates of extreme floods is a major challenge for risk assessment and mitigation. It important to understand quantify the potential sources these reduce support cost-effective safe infrastructure design.In this study, we employ framework based on hydrometeorological modeling chain long continuous simulations estimate (Viviroli et al., 2022). The first element multi-site stochastic weather generator GWEX, which focuses intense precipitation...
In the era of large-sample hydrology (LSH), there is still a lack in availability consistent data related to water quality. To address this gap, we introduce CAMELS-CH-Chem, dataset inspired by recently published CAMELS-Chem for contiguous United States. CAMELS-CH-Chem extends CAMELS-CH (Catchment Attributes and Meteorology Large-sample Studies Switzerland) integrating stream chemical parameters atmospheric deposition 115 monitoring stations across Switzerland. Spanning same period as...
Abstract. Glaciers all over the world are expected to continue retreat due global warming throughout 21st century. Consequently, future seasonal water availability might become scarce once glacier areas have declined below a certain threshold affecting management strategies. Particular attention should be paid glaciers located in karstic environment, as parts of meltwater can drained by underlying karst systems, making it difficult assess availability. In this study tracer experiments,...
Abstract. In this paper we implement a degree day snowmelt and glacier melt model in the Dynamic fluxEs ConnectIvity for Predictions of HydRology (DECIPHeR) model. The purpose is to develop hydrological that can be applied large glaciated snow-fed catchments yet computationally efficient enough include uncertainty streamflow predictions. evaluated by simulating monthly discharge at six gauging stations Naryn River catchment (57 833 km2) central Asia over period 1951 variable end date between...
Modeling of future water systems at the regional scale is a difficult task due to complexity current structures (multiple competing uses, multiple actors, formal and informal rules) both temporally spatially. Representing this in modeling process challenge that can be addressed by an interdisciplinary holistic approach. The assessment system Crans‐Montana‐Sierre area (Switzerland) its evolution until 2050 were tackled combining glaciological, hydrogeological, hydrological measurements with...
We present and test a conceptual methodological approach for interdisciplinary sustainability assessments of water governance systems based on what we call the wheel. The combines transparent identification principles, their regional contextualization through sub-principles (indicators), scoring these indicators deliberative dialogue within an team researchers, taking into account various qualitative quantitative research results. was applied to assessment complex system in Swiss Alps....
Recent flood events show that gaps in the communication channels from warning services to target groups inhibit mitigation. One approach addressing this issue is impact-based warning. We introduce a library-based surrogate model for use systems, tested main river network of Northern Switzerland. To validate model, we compare impacts buildings, persons and workplaces with hazard classification, estimated transient simulations nine extreme precipitation scenarios. With 78 analyzed regions,...

Floods are one of the costliest natural hazards in Switzerland and worldwide. Therefore, society is confronted with questions about protecting people assets from flood risks. Key instruments protective measures, land use regulations, spatial planning, interventions by civil protection units if magnitudes exceed standards. Both prevention preparedness require risk awareness professionals, politicians, public. Risk generally high after an event low a period without major events. However,...
Abstract In flood risk management, the choice of vulnerability functions has a remarkable impact on overall uncertainty modelling damage. The spatial transferability empirical is limited, leading to need for computation and validation region‐specific functions. data‐scarce regions however, this option not feasible. contrast, physical processes model chains can be developed in these because availability global datasets. Here we evaluated implementation synthetic function into model. bases...
Abstract. Estimates for rare to very floods are limited by the relatively short streamflow records available. Often, pragmatic conversion factors used quantify such events based on extrapolated observations, or simplifying assumptions made about extreme precipitation and resulting flood peaks. Continuous simulation (CS) is an alternative approach that better links estimation with physical processes avoids antecedent conditions. However, long-term CS has hardly been implemented estimate (i.e....

Abstract. Glaciers all over the world are expected to continue retreat due global warming throughout 21st century. Consequently, future seasonal water availability might become scarce once glacier areas have declined below a certain threshold affecting management strategies. Particular attention should be paid glaciers located in karstic environment, as parts of melt can drained by souterrain karst systems. In this study tracer experiments, modeling and combined order identify flow paths...
