Demonstration of probabilistic hydrological and atmospheric simulation flood events in the Alpine region (D-PHASE) is made by Forecast Project connection with Mesoscale Programme (MAP). Its focus lies end-to-end forecasting a mountainous such as Alps surrounding lower ranges. scope ranges from radar observations modeling to decision making civil protection agents. More than 30 high-resolution deterministic models coupled some seven various combinations provided real-time online information....

Hydraulic risk maps provide the baseline for land use and emergency planning. Accordingly, they should convey clear information on potential physical implications of different hazards to stakeholders. This paper presents a vulnerability criterion focused human stability in flow specifically devised rapidly evolving floods where life, before than economic values, might be threatened. The body is conceptualized as set cylinders its slipping toppling assessed by forces moments equilibrium....

Abstract. Surface melting is a major component of the Greenland ice sheet surface mass balance, and it affects sea level rise through direct runoff modulation dynamics hydrological processes, supraglacially, englacially subglacially. Passive microwave (PMW) brightness temperature observations are paramount importance in studying spatial temporal evolution due to their long coverage (1979–present) high resolution (daily). However, limitation PMW datasets has been relatively coarse resolution,...

In recent years, flood-related risk has been increasing worldwide, being inundations among the natural disasters which induce maximum damage in terms of economic losses. research reported this paper, a methodology to map flooding residual hazard due levee failure events induced by piping embankments protecting flood-prone areas is proposed. Ensemble simulations are used account for uncertainties location, geometry, and time-evolution breaches. Probabilistic flooding-hazard maps generated...

Precipitation measurements by rain gauges are usually affected a systematic underestimation, which can be larger in case of snowfall. The wind, disturbing the trajectory falling water droplets or snowflakes above gauge, is major source error, but when tipping-bucket recording used, induced evaporation due to heating device must also taken into account. Manual fresh snow equivalent (SWE) were Alpine areas Valtellina and Vallecamonica, Northern Italy, compared with daily precipitation melted...

In mountainous regions, debris flows represent a significant hazard, causing extensive damage and casualties each year. Among the various triggering factors, rainfall is primary driver of in catchments with high sediment availability. Determining critical thresholds for debris-flow initiation therefore essential improving early warning systems mitigating associated risks. This study focuses on:a) Defining using monitoring data collected over relatively short period (three years), even...

The problem of mapping debris-covered glaciers using images derived from satellite-borne optical scanners is addressed in this paper. Results also Terra-ASTER on the Belvedere and Miage glaciers, both located Italian Alps, are presented. Field measurements energy balance modeling indicate that for debris superimposed ice, surface temperatures some degrees colder than pure, to be expected morning. This fact confirmed by processing satellite taking into account thermal band. results black...
