Displaying 15 of about 557 resultsThe study aims to identify and characterize 'hotspots' of flood risk, accounting for spatial variation in social vulnerability, to provide improved insights into the geography of risk and enhance disaster risk planning and response efforts, particularly in lower income countries with limited data or capacity. Exposure to flooding is greatest in low- and…
The main objective of this quarterly report is to show how the European Crisis Management Laboratory (ECML) Mapping Team at the Joint Research Centre (JRC) plays a key role in delineating all the components of disaster event phases with its daily situational awareness reports (ECHO Daily Flash and Daily Maps) and on-demand products (ECHO Situation Maps/…
This study is designed to provide a scientific reference for the establishment of rainstorm and flood disaster prevention system in Guilin region and improve the risk assessment of rainstorm and flood disasters. To realize the goal, a flood risk evaluation model is established by weight analysis methods including the entropy weight method and the analyt…
This article presents a systematic review of quantitative methods proposed in the scientific literature or prescribed by government authorities to assess the hazard associated with natural or anthropic flooding. Flood hazard assessment is a fundamental step in flood risk mapping. Quantitative assessment requires hydrodynamic modelling of the flooding pr…
These hazard maps were prepared using satellite remote sensing data and have been ratified with ground truth by the respective district administrations to ensure effective acceptance of the information. This will enable all stakeholders in assessing flood prone areas for an effective management and informed decision making.
The flood hazard atlas…
The Yukon River Basin (YRB) is one of the most important river networks shared between Canada and The United States, and is one of the largest river basins in the subarctic region of North America. The Canadian part of the YRB is characterized by steeply sloped, partly glaciated mountain headwaters that generate considerable runoff during melt of glacie…
This study introduces a new statistical approach for quantifying the weights used in landslide susceptibility mapping and their associated uncertainty. Mitigating the impacts of landslides requires quantifying the susceptibility of different infrastructures to this hazard through landslide susceptibility mapping. The mapping requires overlaying the spat…
This contributing paper presents a mapping tool that connects the seven World Meteorological Organization (WMO) state of the climate indicators to climate change impacts and the United Nations Sustainable Development Goals (SDGs). Although there is emerging scientific literature on climate change, risk and policy action, the interdisciplinary nature of…
This study explores agent-based tsunami evacuation simulations to compare the evacuation ratio when agents are evacuated to their nearest inland evacuation facility regardless of direction relative to the coastline. Future earthquakes originating in the Nankai Trough and Hyuga-nada Sea near Japan are expected to cause strong tremors and large tsuna…
This contributing paper explores the opportunities offered by digital media mining to complement impact databases. Impact data on past disasters caused by natural hazards (in short, impact data) are of paramount importance for several applications. These include advocacy for investments in disaster risk reduction (DRR) and providing and evidence base fo…
In the Hindu Kush Himalayas (HKH) region, large areas in Afghanistan, Bangladesh, China, India, Myanmar, Nepal, and Pakistan get inundated by floodwater during every rainy season. Among them, Bangladesh has been experiencing record-high floods where four types prevail: flash flood, local rainfall flood, monsoon river flood, and storm-surge flood; a…
This paper addresses the visual communication issues with a focus on natural hazards which vary in time and space (such as the avalanche danger level) or purely in space (such as maps using the Avalanche Terrain Exposure Scale, ATES, to communicate how different terrain is exposed to avalanches). This study is a follow up of a previous study on the effi…
This report presents the results of analysis which collates information on the impacts of flooding and related hazards in communities, public services, infrastructure and businesses in the UK since 2007 from newspaper articles using a form of artificial intelligence called Natural Language Processing (NPL). It has extracted information on flood events f…
This study adopts the 1D–2D model SOBEK to investigate the impact of drainage density on river flow. Coupled 1D–2D hydrodynamic models are widely utilized in food hazard mapping. Previous studies adopted conceptual hydrological models or 1D hydrodynamic models to evaluate the impact of drainage density on river flow. However, the drainage density a…
This paper aims to acquire vulnerability indicators to geo-hydrological hazards and examines an example of mobile phone-based data collection. Geo-hydrological risk reduction is a key issue for local governments in Italy. In this context, a collaboration was undertaken between multiple actors in the La Spezia municipality aimed at: (i) monitoring buildi…
