This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by need for stronger harmonisation research efforts. The procedure involved public consultation through online media, followed two workshops which large number potential science questions were collated, prioritised, and synthesised. In spite diversity participants (230 scientists total), process revealed much about priorities state our science: preference continuity...
Changes in climate, land use, and management impact the occurrence severity of wildland fires many parts world. This is particularly evident Europe, where ongoing changes use have strongly modified fire patterns over last decades. Although satellite data by European Forest Fire Information System provide large-scale statistics across countries, there still a crucial need to collect summarize in-depth local analysis understanding condition associated challenges Europe. article aims general...
An increasing world population is projected to increase water, energy and food requirements, three vital resources for humankind. Projected climate change impacts will aggravate water availability, as well flood risks, especially in urban areas. Nature-based solutions (NBS) have been identified key concepts defuse the expected tensions within Water-Energy-Food (W-E-F) nexus due their multiple benefits. In this paper, authors outlined theories concepts, analyzed real-life case studies,...
Hydropower accounts for about 20% of the worldwide electrical power production. In mountainous regions this ratio is significantly higher. study we present how future projected climatic forcing, as described in regional climate models (RCMs), will affect water resources and subsequently hydropower production downstream plants a glacierized alpine valley (Vispa valley, Switzerland, 778 km 2 ). order to estimate runoff generation production, used error‐corrected downscaled scenarios from...
Abstract The assessment of snow, glacier, and rainfall runoff contribution to discharge in mountain streams is major importance for an adequate water resource management. Such contributions can be estimated via hydrological models, provided that the modeling adequately accounts snow glacier melt, as well runoff. We present a multiple data set calibration approach estimate composition using models with three levels complexity. For this purpose, code conceptual model HBV‐light was enhanced...
Physically based hydrological models describe natural processes more accurately than conceptual but require extensive data sets to produce accurate results. To identify the value of different for improving performance distributed model TOPKAPI we combine a multivariable validation technique with Monte Carlo simulations. The study is carried out in snow and ice‐dominated Rhonegletscher basin, as these types mountainous basins are generally most critical respect availability sensitivity...
In 2013, the International Association of Hydrological Sciences (IAHS) launched hydrological decade 2013–2022 with theme "Panta Rhei: Change in Hydrology and Society". The recognizes urgency research to understand predict interactions society water, support sustainable water resource use under changing climatic environmental conditions. This paper reports on first Panta Rhei biennium 2013–2015, providing a comprehensive that describes scope direction Rhei. We bring together knowledge all...
Abstract Manually collected snow data are often considered as ground truth for many applications such climatological or hydrological studies. However, there sources of uncertainty that not quantified in detail. For the determination water equivalent cover (SWE), different core samplers and scales used, but they all based on same measurement principle. We conducted two field campaigns with 9 commonly used observational measurements research Europe northern America to better quantify...
Nature-Based Solutions (NBS) have been proven to effectively mitigate and solve resource depletion climate-related challenges in urban areas. The COST (Cooperation Science Technology) Action CA17133 entitled “Implementing nature-based solutions for building a resourceful circular city” has established seven circularity (UCC) that can be addressed with NBS. This paper presents the outcomes of five elucidation workshops more than 20 European experts from different backgrounds. These...
Abstract. Drought events and their impacts vary spatially temporally due to diverse pedo-climatic hydrologic conditions, as well variations in exposure vulnerability, such demographics response actions. While hazard severity frequency of past drought have been studied detail, little is known about the effect management strategies on actual how perceived by relevant stakeholders. In a continental study, we characterised assessed perceptions two recent (2018 2019) Europe examined relationship...
The new scientific decade (2023-2032) of the International Association Hydrological Sciences (IAHS) aims at searching for sustainable solutions to undesired water conditions - may it be too little, much or polluted. Many current issues originate from global change, while problems must embrace local understanding and context. will explore crises by actionable knowledge within three themes: interactions, innovative cross-cutting methods. We capitalise on previous IAHS Scientific Decades...

Circular solutions are essential to tackle the imminent challenges of depleting resources and emerging environmental problems. The complex nature material energy systems changing economic technological conditions depend on regional settings accordingly result differently in developed rapidly developing countries world. A wide variety theoretical approaches can be used facilitate a shift from linear use circular systems, e.g., product planning, zero waste management, service-based repairing,...
The hydropower reservoir of Gigerwald is located in the alpine valley Calfeisental eastern Switzerland. lake fed by runoff from rain, snow melt and ice a few small glaciers, as well water collected neighbouring valley. Water resources Alps are projected to undergo substantial changes coming decades. It therefore essential explore climate change impacts catchments with facilities. We present multi-dataset calibration (MDC) using discharge, snowcover data glacier mass balances for an ensemble...
Retention in upstream storage dams results modified riverine water and particle discharge patterns. Particularly, suspended solids input intrusion dynamics downstream lakes are affected by dam operations. In a case study, size‐dependent budgets for peri‐alpine Lake Brienz (Switzerland), of major hydropower installations, were determined recent 8‐year period (1997–2004) compared to hypothetical no‐dam scenarios based on numerical simulations. For this purpose, current tributary loads, as well...
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 Water‐ and sediment‐transfer models are commonly used to explain or predict patterns in the landscape at scales different from those which observations available. These often result of emergent properties that occur because processes water sediment transfer connected ways. Recent advances geomorphology suggest it is important consider, a specific spatio‐temporal scale, structural connectivity system control processes, functional resulting way operate evolve through time. We argue...
The benefits of fractional snow cover area, as an additional dataset for calibration, were evaluated Icelandic catchment with a low degree glaciation and limited data. For this purpose, Hydrological Projections the Environment (HYPE) model was calibrated Geithellnaá in south-east Iceland using daily discharge (Q) data satellite-retrieved MODIS (SC) images, multi-dataset calibration (MDC) approach. By comparing results only obtained both datasets, value SC identified. Including improved...
