Climate change is profoundly affecting the global water cycle, increasing likelihood and severity of extreme water-related events. Better decision-support systems are vital to accurately predict monitor environmental disasters optimally manage resources. These must integrate advances in remote sensing, situ , citizen observations with high-resolution Earth system modeling, artificial intelligence (AI), information communication technologies, high-performance computing. Digital Twin (DTE)...
Abstract Snow in mountainous regions is a key water resource from local to continental scales. However, the link between increasingly frequent snow droughts and socio-hydrologic impacts headwaters lowlands not fully understood. To untangle this relationship, here we combine climate reanalyses with range of data terrestrial storage, streamflow, emergency water-use restrictions for archetypal 2022 drought Po basin (Italy). We find that persistent high-pressure ridge during winter 2021–2022...
Abstract. We investigate snow depth distribution at peak accumulation over a small Alpine area ( ∼ 0.3 km2) using photogrammetry-based surveys with fixed-wing unmanned aerial system (UAS). These devices are growing in popularity as inexpensive alternatives to existing techniques within the field of remote sensing, but assessment their performance areas map is still an open issue. Moreover, several attempts UASs have used multi-rotor systems, since they guarantee higher stability than...
Abstract. Multi-year droughts in Mediterranean climates may shift the water balance, that is, partitioning rule of precipitation across runoff, evapotranspiration, and sub-surface storage. Mechanisms causing these shifts remain largely unknown are not well represented hydrologic models. Focusing on measurements from headwaters California's Feather River, we found also mixed rain–snow basins a lower fraction was partitioned to runoff during multi-year compared non-drought years. This...
Abstract. Satellite-based Earth observations (EO) are an accurate and reliable data source for atmospheric environmental science. Their increasing spatial temporal resolutions, as well the seamless availability over ungauged regions, make them appealing hydrological modeling. This work shows recent advances in use of high-resolution satellite-based EO In a set six experiments, distributed model Continuum is up Po River basin (Italy) forced, turn, by satellite precipitation evaporation, while...
Abstract. In a warming climate, periods with lower than average precipitation will increase in frequency and intensity. During such periods, known as meteorological droughts, the decline annual runoff may be proportionally larger corresponding precipitation. Reasons behind this exacerbation of deficit during dry remain largely unknown, challenges predictability when occur future how intense it be. work, we tested hypothesis that droughts is common feature across climates, driven by...
Abstract. We present IT-SNOW, a serially complete and multi-year snow reanalysis for Italy (∼ 301 × 103 km2) – transitional continental-to-Mediterranean region where plays an important but still poorly constrained societal ecological role. IT-SNOW provides ∼ 500 m daily maps of water equivalent (SWE), depth, bulk density, liquid content the initial period 1 September 2010–31 August 2021, with future updates envisaged on regular basis. As output operational chain employed in real-world civil...
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...
Performing two independent surveys in 2016 and 2017 over a flat sample plot (6700 m 2 ), we compare snow-depth measurements from Unmanned-Aerial-System (UAS) photogrammetry new high-resolution laser-scanning device (MultiStation) with manual probing, the standard technique used by operational services around world. While previous comparisons already laser scanners, tested for first time MultiStation, which has different measurement principle is thus capable of millimetric accuracy. Both...
Abstract. Data of liquid water flow around a capillary barrier in snow are still limited. To gain insight into this process, we carried out observations dyed infiltration layered at 0 °C during cold laboratory experiments. We considered three different finer-over-coarser textures and input rates. By means visual inspection, horizontal sectioning, measurements content (LWC), barriers associated preferential were characterized. The dynamics each sample also simulated solving the Richards...
Abstract. Precipitation orographic enhancement is the result of both synoptic circulation and topography. Since high-elevation headwaters are often sparsely instrumented, magnitude distribution this enhancement, as well how they affect precipitation lapse rates, remain poorly understood. Filling knowledge gap would allow a significant step ahead for hydrologic forecasting procedures water management in general. Here, we hypothesized that spatially distributed, manual measurements snow depth...
Abstract This paper investigates how atmospheric circulation and orography affect the spatial variability of extreme precipitation in terms depth–duration–frequency (DDF) curve parameters. To this aim, Italian territory was considered because it is characterized by a complex different dynamics regimes. A database 1494 time series with more than 20 years maximum annual data collected for durations 1, 3, 6, 12, 24 h. For each series, parameters DDF curves were estimated using statistical...
Maximum annual daily precipitation is a fundamental hydrologic variable that does not attain asymptotic conditions. Thus the classical extreme value theory (i.e., Fisher-Tippett's theorem) apply and recurrent use of Generalized Extreme Value distribution (GEV) to estimate quantiles for structural-design purposes could be inappropriate. In order address this issue, we first determine exact maximum starting from Markov chain in closed analytical form under hypothesis stochastic independence....
Abstract. An inconsistent relationship between precipitation and runoff has been observed drought non-drought periods, with less usually during droughts than would be expected based solely on deficit. Predictability of these shifts in the precipitation–runoff is still challenging, largely because underlying hydrologic mechanisms are poorly constrained. Using 30 years data for 14 basins California, we show how Budyko framework can leveraged to decompose versus into “regime” shifts, which...
Abstract. Trustworthy estimates of snow water equivalent and depth are essential for resource management in snow-dominated regions. While ensemble-based data assimilation techniques, such as the Ensemble Kalman Filter (EnKF), commonly used this context to combine model predictions with observations therefore improve performance, these ensemble methods computationally demanding thus face significant challenges when integrated into time-sensitive operational workflows. To address challenge, we...
Climate change significantly impacts snow dynamics, thereby affecting water resources, especially in countries like Türkiye, where is crucial for supply. This study focuses on one of the largest Mediterrenain river basins, Seyhan Basin (21,890 km²), contributing to Türkiye's overall resources. The basin's extensive agricultural activities and significant hydropower potential necessitate sustainable management its long-term sustainability. complex mountainous...
The Alps are a crucial water reservoir for over 170 million people in Europe, storing as snow and ice during the cold season releasing it warm season. However, climate warming is causing earlier snowmelt glacier shrinkage, leading to mismatch between availability peak demand, thereby increasing risk of shortages conflicts among key users such agriculture, energy, tourism. In this framework, skillful seasonal predictions combined with snow-hydrological modeling might help early warning...
Measuring evapotranspiration (ET) is crucial for understanding the complex interactions among atmosphere, vegetation, and land. In context of global climate change, distributed quantification actual ET has become even more important, as alterations in hydrological cycle affect water availability, ecosystem dynamics, thus agriculture.In this study we present a network to directly measure across different land uses Aosta Valley (Western Italian Alps) Agile Arvier project. Supported by funding...
