Uncertainty and sensitivity analysis of coastal flood damage estimates in the west of the Netherlands
Natural Hazards and Earth System Sciences - Tập 12 Số 4 - Trang 1045-1058
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. This all...
Physical vulnerability modelling in natural hazard risk assessment
Natural Hazards and Earth System Sciences - Tập 7 Số 2 - Trang 283-288
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 as
mass...
Scale orientated analysis of river width changes due to extreme flood hazards
Natural Hazards and Earth System Sciences - Tập 11 Số 8 - Trang 2137-2147
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
measurements ...
Comparison of event landslide inventories: the Pogliaschina catchment test case, Italy
Natural Hazards and Earth System Sciences - Tập 14 Số 7 - Trang 1749-1759
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 preparation
of e...
Evaluation of far-field tsunami hazard in French Polynesia based on historical data and numerical simulations
Natural Hazards and Earth System Sciences - Tập 7 Số 2 - Trang 195-206
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
events), ...
A nonlinear model coupling rockfall and rainfall intensity based on a four year measurement in a high Alpine rock wall (Reintal, German Alps)
Natural Hazards and Earth System Sciences - Tập 9 Số 4 - Trang 1425-1432
Abstract. A total of more than 140 000 kg of small-magnitude rockfall deposits
was measured in eight rockfall collectors of altogether 940 m2 in size between
1999–2003 below a 400–600 m high rock face in the Reintal, German Alps.
Measurements were conducted with a temporal resolution up to single days to
attribute rockfall intensity to observed triggering events. Precipitation was
assessed by a ra...
Regional disaster impact analysis: comparing input–output and computable general equilibrium models
Natural Hazards and Earth System Sciences - Tập 16 Số 8 - Trang 1911-1924
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 widely
used,...
A preliminary investigation of radar rainfall estimation in the Ardennes region and a first hydrological application for the Ourthe catchment
Natural Hazards and Earth System Sciences - Tập 5 Số 2 - Trang 267-274
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 and conv...
Microseismic activity analysis for the study of the rupture mechanisms in unstable rock masses
Natural Hazards and Earth System Sciences - Tập 10 Số 4 - Trang 831-841
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, was ins...
Góc nhìn được mời: Góc nhìn thủy văn về ngưỡng cường độ - thời gian mưa đối với sự khởi phát sạt lở đất: đề xuất ngưỡng thủy-meteo Dịch bởi AI
Natural Hazards and Earth System Sciences - Tập 18 Số 1 - Trang 31-39
Tóm tắt. Nhiều vụ sạt lở đất nông và dòng chảy sỏi được khởi phát bởi mưa. Do
đó, đánh giá nguy cơ sạt lở khu vực thường dựa trên các ngưỡng cường độ - thời
gian (ID) mưa thu được từ thực nghiệm và các danh mục sạt lở đất. Thông thường,
hai đặc điểm của các sự kiện mưa được vẽ và gán nhãn với sự xuất hiện hoặc không
xuất hiện của sạt lở (nông). Sau đó, một đường phân cách hoặc khu vực được vẽ,
chủ...
