Conference Paper
Full-text available
Climate change is likely to transform dam risks in the mid and long term. Management strategies must be adapted to new climate scenarios in order to define the most efficient implementation sequence of risk reduction measures. A comprehensive process based on the risk analysis framework has been proposed by the authors that encompasses all the phas...
Article
Full-text available
This paper presents a practical approach for adaptive management of dam risk based on robust decision-making strategies coupled with estimation of climate scenario probabilities. The proposed methodology, called Multi-Prior Weighted Scenarios Ranking, consists of a series of steps from risk estimation for current and future situations through the d...
Article
Full-text available
Dams are critical infrastructures whose safety must be properly managed. Traditional decision-making approaches often assume the stationarity of factors defining risk. However, dam risk is susceptible to evolve with time. Risk can no longer be considered a static but a time-dependent concept which cumulative value must be reduced for different time...
Article
Full-text available
Glacier shrinkage – accelerated over the last decades due to climate change – is exposing large areas in mountain regions worldwide. But an even dire consequence of the melting ice is the forming of more glacier lakes, which are increasing in size. Glacial lakes have caused some of the world’s most devastating floods, for example, in the Andes, Him...
Article
Full-text available
Dam safety is increasingly subjected to the influence of climate change. Its impacts must be assessed through the integration of the various effects acting on each aspect, considering their interdependencies, rather than just a simple accumulation of separate impacts. This serves as a dam safety management supporting tool to assess the vulnerabilit...
Chapter
Full-text available
In most analysis techniques, dam risk is often assessed at one point in time. However, risk is susceptible to evolve with time as sequence of measures are implemented or as new conditions affecting dam safety are expected (e.g. the alterations due to climate change). A broader perspective to dynamically evaluate time issues in the prioritization se...

Poster
Full-text available
The impact of climate change on the drought occurrence based on the SPI values has been analyzed and applied to the Valais region, in Switzerland. The new Swiss scenarios CH2018 (Swiss Climate Scenarios CH2018, 2018) have been used to assess how climate change is expected to affect drought occurrence in the Valais region, Switzerland. The CH2018 da...
Conference Paper
Hydrological forecasting in Alpine environments continues to represent a major challenge despite of technological development. The spatial variability of precipitation as well as the importance of snow-melt in spring are two major issues. The present article explores the use of various precipitation products for the calibration of an Alpine catchme...
Article
Full-text available
This paper presents a simple tool for the assessment of maximum overtopping probabilities of dams. The tool is based on empirical relations between the overtopping probability and the basic hydrological and hydraulic characteristics of the dam-reservoir system: the unit storage capacity, V*F, and the unit spillway capacity, Q*Cap, both weighted wit...
Article
Full-text available
Dams as well as protective dikes and levees are critical infrastructures whose associated risk must be properly managed in a continuous and updated process. Usually, dam safety management has been carried out assuming stationary climatic and non-climatic conditions. However, the projected alterations due to climate change are likely to affect diffe...
Chapter
Full-text available
Glacial-related risks are a key issue in Peruvian high mountains. The April 2010 outburst of the glacial Laguna 513 in the Cordillera Blanca (Ancash), above the city of Carhuaz, is an emblematic example. In the context of the multidisciplinary project “Glaciares 513—Adapting to climate change and reducing disaster risks due to receding Andes glacie...

Article
Full-text available
Drought indices based on precipitation are commonly used to identify and characterize droughts. Due to the general complexity of droughts, the comparison of index-identified events with droughts at different levels of the complete system, including soil humidity or river discharges, relies typically on model simulations of the latter, entailing pot...

While developing a Risk Model, the flood routing analysis' objective is to provide the system loading (peak reservoir levels, overtopping durations, discharges …). In order to accomplish this, the needed data are: incoming hydrographs, starting pool levels, spillway and outlet works properties (including functionality), reservoir physical propertie...
