Abstract. Studies on recent climate trends from the Himalayan range are limited, and even completely absent at high elevation (> 5000 m a.s.l.). This study specifically explores southern slopes of Mt. Everest, analyzing time series temperature precipitation reconstructed seven stations located between 2660 5600 a.s.l. during 1994–2013, complemented with data all existing ground weather both sides mountain (Koshi Basin) over same period. Overall we find that main most significant increase...
Snow stores a significant amount of water in mountain regions. The decrease storage the snowpack can have relevant impacts on supply for and lowland areas that rely snow melting. In this work, we modelled Water Equivalent (SWE) using daily depth (HS) data obtained from 19 historical HS measurement stations located southern European Alps (Italy). Then, analysed long-term (1930–2020) variability monthly Standardised SWE Index (SSWEI) its links with climate change large-scale atmospheric...
Abstract Snow represents a fundamental water resource for mountain and lowland areas. Changes in the frequency magnitude of snow droughts can significantly impact societies ecosystems that rely on snowmelt to satisfy their demands. Here we documented quantified drought affected Italian Alps during early 2020s. We used 15 long-term snow-depth series (period 1930–2023, elevation range: 864–2200 m a.s.l.) simulate equivalent (SWE), conjunction with climatic reanalysis data river discharge...
Abstract Understanding the response of Himalayan glaciers to global warming is vital because their role as a water source for Asian subcontinent. However, great uncertainties still exist on climate drivers past and present glacier changes across scales. Here, we analyse continuous hourly station data from glacierized elevation (Pyramid station, Mount Everest) since 1994 together with other ground observations reanalysis. We show that decrease in maximum air temperature precipitation occurred...
Abstract Groundwater resources are of utmost importance in sustaining water related ecosystems, including humans. The long-lasting impacts from anthropogenic activities require early actions, owing to the natural time lag groundwater formation and renewal. European Union (EU) policy, within implementation Water Framework Directive (WFD), requires Member States identify reverse any significant sustained upward trend concentration pollutants, defining specific protection measures be included...
Abstract. Various downscaling techniques have been developed to bridge the scale gap between global climate models (GCMs) and finer scales required assess hydrological impacts of change. Such may be grouped into two approaches: deterministic dynamical (DD) statistical (SD). Although SD has traditionally seen as an alternative DD, recent works on aimed combine benefits these approaches. The overall objective this study is whether a DD processing performed before permits obtain more suitable...
ABSTRACT This study analyses the precipitation pattern in Tiber River basin (central Italy) to determine trends, possible change points, periodicity and relationships with global climate indices, such as North Atlantic Oscillation ( NAO ) index. The dataset is composed of daily rainfall time series, recorded at 21 102 different sampling stations, from 1952 2007. following quantities were analysed both an annual seasonal scale: cumulative precipitation, number rainy days, mean intensity,...
Among different uses of freshwater, irrigation is the most impacting groundwater resource, leading to water table depletion and possible seawater intrusion. The unbalance between availability resources demand currently exacerbated could become worse in near future accordance with climate change observations scenarios provided by Intergovernmental Panel on Climate Change (IPCC). In this context, Increasing Maximum Capacity surface reservoir (IMC) Managed Aquifer Recharge (MAR) are adaptation...
Lake Bracciano has been historically used as a strategic water reservoir for the city of Rome (Italy) since ancient times. However, following severe crisis 2017, abstraction completely stopped. The relative impact various drivers change (climatological and management) on fluctuations in lake level is not yet clear. To quantify this impact, we applied Random Forest (RF) machine learning approach, taking advantage century observations. Since late 1990s monthly variation levels doubled,...
Abstract The available literature on natural hazard risk analysis focused the implementation of water safety plans (WSPs) is surprisingly quite poor, despite significant increase in number and severity disasters adverse effects drinking supply systems generated by hazards. At same time, WSPs that conveniently account for hazards with a comprehensive approach ‘from source to tap’ are still scarce as they typically occur at larger spatial scales adequate prevention, mitigation adaptation...
Abstract Daily precipitation and river discharge (1920-2010) in the Tiber basin (Central Italy) have been analyzed by means of standardized indices at annual seasonal scale; existence trends has verified non parametric Mann-Kendall. Advantages/disadvantages arising from use order to identify climatic signal scale are discussed as well relation between rainfall global (i.e. North Atlantic Oscillation Index).
Abstract Despite its strong impact on the time evolution of snowpack, current estimation new snow density ( ρ hn ) is usually accomplished either by using local empirical techniques or assuming a constant density. Faced with lack an model valid for wide spatial scale and supported suitable number observations, this study aims to develop simple monthly linear regression models at entire Italian Alpine chain based 12,112 snowfall observations 122 stations, only air temperature as predictor....
Abstract The Mediterranean area is one of the most important “hotspot” where effects climate change are more evident, with an increase extreme events such as hot waves and intense droughts. From this perspective, central Italy, which in recent past suffered from impact negative anomalies precipitation on water resources, shows peculiar characteristics, being its meteoclimatic regime determined by global, regional local factors. In context, study aims at exploring variability time space Italy...
Abstract The assessment of flood impact on a Water Supply System (WSS) requires comprehensive approach including several scales analysis and models should be managed in the Safety Plans (WSP), as recommended EU Directive 2020/2184. Flooding can affect quality groundwater surface water resources cause supply service interruption due to damaged infrastructures. A complete address WSS is required but not yet available, while only specific aspects were investigated details. This work introduces...
The aquifer system, which is the resource of water for city Milano (Italy), a multilayered aquifer, characterized by sandy and sandy-gravel units, connected discontinuous aquitards. recharge area phreatic close to prealpine area, some tens kilometers north city; nevertheless local given rain infiltration through soil not negligible contributes mass balance aquifer. A field campaign was carried out 16months in suburban Lambro Park evaluate due rainfall unsaturated zone; table this lies about...
Conditions of shortage in a water supply system (WSS) occur when the available resources are unable to satisfy related demand (failure). The definition risk conventionally relies on three indexes that capture characteristics possible failures terms probability occurrence (reliability), duration (resiliency), and intensity (vulnerability). Although conceptual bases for these definitions largely acknowledged, operative way define them can affect final value shortage, making it difficult...
