Uncertainty and sensitivity analysis of coastal flood damage estimates in the west of the NetherlandsNatural Hazards and Earth System Sciences - Tập 12 Số 4 - Trang 1045-1058
Hans de Moel, Nathalie E. M. Asselman, J.C.J.H. Aerts
Abstract. Uncertainty analyses of flood damage assessments generally require a large amount of model evaluations. This is often hampered by the high computational costs necessary to calculate flood extents and depths using 2-dimensional flow models. In this paper we developed a new approach to estimate flood inundation depths that can be incorporated in a Monte Carlo uncertainty analysis. ...... hiện toàn bộ
Physical vulnerability modelling in natural hazard risk assessmentNatural Hazards and Earth System Sciences - Tập 7 Số 2 - Trang 283-288
John Douglas
Abstract. An evaluation of the risk to an exposed element from a hazardous event requires a consideration of the element's vulnerability, which expresses its propensity to suffer damage. This concept allows the assessed level of hazard to be translated to an estimated level of risk and is often used to evaluate the risk from earthquakes and cyclones. However, for other natural perils, such...... hiện toàn bộ
Scale orientated analysis of river width changes due to extreme flood hazardsNatural Hazards and Earth System Sciences - Tập 11 Số 8 - Trang 2137-2147
G. Krapesch, Christoph Hauer, Helmut Habersack
Abstract. This paper analyses the morphological effects of extreme floods (recurrence interval >100 years) and examines which parameters best describe the width changes due to erosion based on 5 affected alpine gravel bed rivers in Austria. The research was based on vertical aerial photos of the rivers before and after extreme floods, hydrodynamic numerical models and cross sectional me...... hiện toàn bộ
Comparison of event landslide inventories: the Pogliaschina catchment test case, ItalyNatural Hazards and Earth System Sciences - Tập 14 Số 7 - Trang 1749-1759
Alessandro Mondini, E. Villanueva, Marco Cavalli, Lorenzo Marchi, Gerardo Herrera, Fausto Guzzetti
Abstract. Event landslide inventory maps document the extent of populations of landslides caused by a single natural trigger, such as an earthquake, an intense rainfall event, or a rapid snowmelt event. Event inventory maps are important for landslide susceptibility and hazard modelling, and prove useful to manage residual risk after a landslide-triggering event. Standards for the preparat...... hiện toàn bộ
Evaluation of far-field tsunami hazard in French Polynesia based on historical data and numerical simulationsNatural Hazards and Earth System Sciences - Tập 7 Số 2 - Trang 195-206
Anthony Sladen, Hélène Hebert, François Schindelé, D. Reymond
Abstract. The first tsunami hazard map of French Polynesia is presented here on the basis of historical data, and numerical simulations. French Polynesia, because of its central position in the most tsunami prone ocean, the Pacific, is strongly exposed to far-field tsunamis. As no previous study on the area had been conducted, we compiled catalogues of all the historical observations (14 ...... hiện toàn bộ
Regional disaster impact analysis: comparing input–output and computable general equilibrium modelsNatural Hazards and Earth System Sciences - Tập 16 Số 8 - Trang 1911-1924
Elco Koks, Lorenzo Carrera, Olaf Jonkeren, Jeroen C. J. H. Aerts, Trond Husby, Mark Thissen, Gabriele Standardi, Jaroslav Myšiak
Abstract. A variety of models have been applied to assess the economic losses of disasters, of which the most common ones are input–output (IO) and computable general equilibrium (CGE) models. In addition, an increasing number of scholars have developed hybrid approaches: one that combines both or either of them in combination with noneconomic methods. While both IO and CGE models are wide...... hiện toàn bộ
A preliminary investigation of radar rainfall estimation in the Ardennes region and a first hydrological application for the Ourthe catchmentNatural Hazards and Earth System Sciences - Tập 5 Số 2 - Trang 267-274
Alexis Berne, M. ten Heggeler, R. Uijlenhoet, Laurent Delobbe, Philippe Dierickx, Micha Werner
Abstract. This paper presents a first assessment of the hydrometeorological potential of a C-band doppler weather radar recently installed by the Royal Meteorological Institute of Belgium near the village of Wideumont in the southern Ardennes region. An analysis of the vertical profile of reflectivity for two contrasting rainfall events confirms the expected differences between stratiform ...... hiện toàn bộ
Microseismic activity analysis for the study of the rupture mechanisms in unstable rock massesNatural Hazards and Earth System Sciences - Tập 10 Số 4 - Trang 831-841
David Amitrano, M. Arattano, Marta Chiarle, G. Mortara, Cristina Occhiena, Marina Pirulli, Claudio Scavia
Abstract. Rockfalls are common instabilities in alpine areas and can cause significant damage. Since high mountains have been affected by an increasing number of these phenomena in the last years, a possible correlation with permafrost degradation induced by climate change has been hypothesized. To investigate this topic, a monitoring system, made of 5 triaxial geophones and 1 thermometer...... hiện toàn bộ
