The German Research Network for Natural Disasters (DFNK) linked 15 partners with scientific expertise in the field of natural hazards. Main objectives were the development and provision of the scientific fundamentals for an advanced risk management of important natural disasters in Germany, i.e., floods, earthquakes, storms and wildland fires. This included risk analyses, the development of information systems for supporting disaster management, and recommendations for risk reduction measures. This paper gives an overview of DFNK and summarises its experiences concerning multidisciplinarity and user-orientation. It illustrates the concept of risk chains, causally linking the different processes from hazard to risk. The step from hazard to risk requires interdisciplinary research teams. The experiences show that integrative concepts allow results not achievable with mono-disciplinary approaches. Integrative approaches pave the way to harmonised safety considerations taking into account the different hazards in a region within a common framework. User-orientation, policy advice and development of operational tools are key issues of disaster research. The experiences of DFNK illustrate the limitations of a research network in bridging the gap between research and application within rather short-term projects. Successful cooperation with users could be established by those activities where, at the beginning of the project, a user was identified who had a strong interest in solving an urgent problem.  相似文献

The development of new and better methods for preventing and managing natural disasters requires a variety of different data sets, covering the range from referenced data, e.g. topographic data and digital elevation models, to various kinds of thematic data, e.g. data about soil, vegetation and land usage as well as monitoring data like precipitation and water levels. So a well-organised data and information management and the implementation of a modern processing environment to acquire, store, analyse and visualise data were decisive for the success of the German Research Network Natural Disasters (DFNK). An information infrastructure was established to support data management and information flows inside the network. A web-based portal offers general information to the public and internal documents, data and software tools to the project community. A catalog service allows the overview of existing but distributed data scombined with flexible data retrieval. Based on internet technology and global standards these concepts contribute to a superior information infrastructure and finally substantiate to the development of Spatial Data Infrastructures (SDI). SDIs aim is to improve availability and usability of spatial data for the manifold application areas. Disaster management is one field depending on a very high level on high-quality data equipment, and on a working SDI.  相似文献

Landslide susceptibility mapping is a vital tool for disaster management and planning development activities in mountainous terrains of tropical and subtropical environments. In this paper, the weights-of-evidence modelling was applied, within a geographical information system (GIS), to derive landslide susceptibility map of two small catchments of Shikoku, Japan. The objective of this paper is to evaluate the importance of weights-of-evidence modelling in the generation of landslide susceptibility maps in relatively small catchments having an area less than 4 sq km. For the study area in Moriyuki and Monnyu catchments, northeast Shikoku Island in west Japan, a data set was generated at scale 1:5,000. Relevant thematic maps representing various factors (e.g. slope, aspect, relief, flow accumulation, soil depth, soil type, land use and distance to road) that are related to landslide activity were generated using field data and GIS techniques. Both catchments have homogeneous geology and only consist of Cretaceous granitic rock. Thus, bedrock geology was not considered in data layering during GIS analysis. Success rates were also estimated to evaluate the accuracy of landslide susceptibility maps and the weights-of-evidence modelling was found useful in landslide susceptibility mapping of small catchments.  相似文献

灾害信息系统和地理信息的组合进行因特网上的发布和综合研究已经成为灾害研究的一种趋势.SVG技术作为一种新的因特网矢量图形标准,对降低灾害研究信息发布的成本、减低网络压力、提高信息交换的可能性提供了一个新的途径.文中以一个灾害发布网站为实例对其实用性和未来前景进行了探讨,在实践上发现,当前的浏览器由于还没有实现对SVG技术的内置支持,对使用的方便性有一些影响,但对提高系统的响应速度,降低webGIS的制作难度,提供更加集成化的网站等有诸多优点.基于SVG结构的自然灾害信息管理系统很大程度上克服了我们以往的灾害信息系统负载过重、数据交换困难、系统更新慢、系统的使用者多为专业人员等诸多缺点,使我们可以在全国甚至更大范围内宣传减灾、救灾,实施灾害管理,是灾害信息管理系统的一个重要的发展方向.  相似文献

The Mediterranean wetlands are unique in biological diversity and provide multiple benefits, constituting a great water reserve for the planet and producing biomass and nutrients for the trophic chain. However, the increasing human impact and socio-economic development in recent decades have caused important losses in these ecosystems. This work was carried out in the Natural Park of L’Albufera (Valencia, Spain), which includes a coastal lagoon, marshlands, dunes and pinewoods, surrounded by rice fields and orchard in its non-urbanized part. Despite this great ecological value, it suffers impacts derived from the high human and industrial occupation and the hydrological contributions of the connected irrigation systems. The study focused on the development of a combined methodology, based on environmental forensics principles, with the aim of identifying the presence, flow paths and spatial distribution of illicit drugs entering the Natural Park. It is organized around two major procedures: analysis of 16 water samples and application of Geographical Information Systems (GIS) integrating different sources and data formats, as analysis of 14 drugs of abuse by Liquid Chromatography-Mass Spectrometry techniques, and social and environmental data in either GIS layers or tabular digital formats. Results show that, at present, most analyzed drugs have been identified in all sample points. Besides the population distribution pattern, the traditional irrigation system connected to sewage treatment plant (STP) locations is the way by which illicit substances are introduced into the Natural Park waters.  相似文献

Data management is the key of geotechnical risk management and disaster prevention providing right information at right time and right place. It supports regular construction cycles as well as handling of exceptional situations occurring probably during execution stages where the detailed knowledge of the actual state of construction is especially important. The web-based client–server software platform DoMaMoS was developed to cover all aspects in a new fashion. Main parts of the software are a graphical user interface, a SQL database and a controller application. Software development concerned user-friendly handling, geotechnical monitoring, security aspects, rapid access and adaptivity during a running project. Basic ideas and main features of the developed software are described and the practical application is shown.  相似文献

Landslide susceptibility zonation (LSZ) is necessary for disaster management and planning development activities in mountainous regions. A number of methods, viz. landslide distribution, qualitative, statistical and distribution-free analyses have been used for the LSZ studies and they are again briefly reviewed here. In this work, two methods, the Information Value (InfoVal) and the Landslide Nominal Susceptibility Factor (LNSF) methods that are based on bivariate statistical analysis have been applied for LSZ mapping in a part of the Himalayas. Relevant thematic maps representing various factors (e.g., slope, aspect, relative relief, lithology, buffer zones along thrusts, faults and lineaments, drainage density and landcover) that are related to landslide activity, have been generated using remote sensing and GIS techniques. The LSZ derived from the LNSF method, has been compared with that produced from the InfoVal method and the result shows a more realistic LSZ map from the LNSF method which appears to conform to the heterogeneity of the terrain.  相似文献

During disasters, many researchers highlight the efficiency of the various information techniques that are used for emergency response. However, only a few information systems consider on-site and off-site information requirements synchronously. The results achieved by the emergency responders will not be as effective as they should be, since the emergency responders cannot access necessary information. Therefore, this study proposed an approach for dealing with three problems associated with emergency situations, i.e., inadequate escape guidelines for people, incomplete geographical information for relief workers, and insufficient on-site information for disaster managers. In a simulated scenario, when serious debris flows occurred, this study tested the approach. The test results showed that the people rapidly finished self-evacuation, the relief workers effectively completed their on-site relief work, and the disaster managers successfully managed the on-site activities regarding the people and relief workers. Overall, the recommended approach improved information access for emergency response and provided a useful reference for similar applications in disaster management.  相似文献
