Risk factors for driving into flooded roads 总被引:2,自引:0,他引:2
Motor vehicle-related deaths account for more than half of all flood fatalities in the United States, but to date, very little is known about the risk factors associated with why people drive into flooded roads. Using data from survey questionnaires administered in Denver, CO, and Austin, TX, this paper suggests that people who do not take warnings seriously are more likely to drive through flooded roads, as are people aged 18–35, and those that do not know that motor vehicles are involved in more than half of all flood fatalities. In Denver, people who have not experienced a flood previously and those who do not know they live in flood-prone areas are also more likely to drive into flooded roads. 相似文献

We propose a suite of actions for strengthening water governance in contexts with complex, multi-tiered arrangements. In doing so, we focus on the collective water policies and approaches of the United Kingdom (UK), including those of devolved governments, which confront a host of serious water-related challenges—from massive flooding of urban areas and agricultural lands, to pressure on aquifers from rising water demand and drought. Further complexity in addressing these challenges has emerged in the wake of the June 2016 vote to leave the European Union (EU), so-called ‘Brexit’, and the ensuing ‘separation process’ with uncertainties for institutional and governance arrangements to follow. We make ten proposals for improving and reinvigorating water policy in complex, multi-layered situations, and comment specifically on their application in the UK setting. These are: put in place a system-wide water policy; fully embrace community-led nested river basin planning and management; fully fund river basin planning and management; re-focus the policy framing; use best-available data and information; create conversational spaces and become a more water-literate society; mobilise people; support and sustain core community networks; underpin river basin plans with regulatory provisions and effective monitoring and enforcement; and address systemic institutional amnesia. Individually and collectively, we contend that these actions will have a marked effect on transforming the planning and management of water resources. A system-wide water policy that maintains and builds on the substantive biophysical and socio-economic benefits delivered through implementation of the EU Water Framework Directive, together with the more recent Floods Directive, will galvanise stewardship of water in the UK. We urge more active engagement with and empowerment of the multiplicity of system ‘actors’, and highlight the role of non-government actors in a post-Brexit world as conduits for reaching out to and connecting directly with a wide range of water-related actors, especially across the EU. While attention to-date has focused on a plethora of specifically water-related projects, initiatives, plans and regulations, what is really needed is a systemic, long-term view of water resource management. 相似文献

Abstract Warnings and emergency planning for flooding are based on the reality that no matter how thorough our investigations and flood prevention efforts through engineered structural works or land use management, some risk will always remain. This paper examines recent experience with flood warnings in the UK and continental Europe. It combines this experience with an overview of the relevant literature to identify lessons for incorporation into policy, and problem areas which would most obviously benefit from additional research. Throughout, the emphasis is on the non-engineering aspects of warning systems. Results indicate that much is being achieved in terms of the detail of warning design, but the broader issues seem to be largely ignored by both the research literature and practice. First among these broader issues is the failure, by those charged with warning system development and operation, to conceptualise the warning task as one based explicitly on the needs of those at risk. Making this happen will require the development of processes to build the necessary culture of cooperation and learning among the many organisations involved. 相似文献

In 1977 the Government of New South Wales introduced a flood prone lands policy which attempted to break with the past emphasis on structural works. Cornerstones of the policy were the preparation of floodplain maps, and use of the 1:100 (100 year or 1%) flood to delineate floodplains and 1:20 flood for floodway definition. The fiscal and regulatory elements of the policy were to be applied more or less uniformly within the two zones. At first there was little effective opposition to the program, but this changed when large areas of Sydney, which had not been inundated since development, were mapped. Local government concern over issues of legal liability led to decisions which in turn prompted opposition to the policy from residents' action groups and property development interests. A perceived drop in property values provided the main motivation for action by residents. This pressure for change, which intensified just before the 1984 state election, saw the policy overturned.
The new policy gives local government greater responsibility for floodplain management. State authorities have withdrawn from floodplain mapping, although technical advice will continue to be provided, and there are no longer any uniform floodplain or floodway definitions. Policy implementation is to be guided by a Manual which attempts to define flood hazard in terms of both physical and social criteria. 相似文献

This research examines sources of information for flash floods in two large metropolitan areas, Denver, CO, and Austin, TX. Previous research has noted that information delivery systems for weather forecasts are geared toward the cultural majority and suggests that inadequate warnings are a primary contributor to deaths and injuries from hazards. This investigation used chi-square analysis to determine the prime warning source preferences and preferred time of day for receiving different media. Results indicate that successful warning messages need to be targeted toward specific sub-populations if the warning is to be received, understood, and responded to properly. 相似文献

Monitoring morphological and vegetation changes and flow events in dryland river channels 总被引:1,自引:0,他引:1
Hooke JM 《Environmental monitoring and assessment》2007,127(1-3):445-457
Monitoring of impacts of floods in river valleys of dryland regions has become important with the onset and threats of desertification
and is likely to become even more vital with predictions of increased effects of climate and land use change. It is also needed
in order to conform to requirements of the EU Water Framework Directive. Monitoring in such regions sets particular challenges.
This paper explains a system of low-cost monitoring of changes in morphology, vegetation and sediment cover in channels and
valley floors of ephemerally flowing streams. It has been applied in SE Spain for 10 years and has proved very effective.
In particular, the use of simple crest-stage recorders for measuring flow height and the use of real-time differential GPS
for rapid and accurate survey and for relocating points have proved very valuable. Part of the monitoring is focused on the
interaction of plants and channel processes. Small changes in and around vegetation associated with flow events have been
detected by a combination of quadrat surveys and cross-profiling of the channel. A range of flow events has been measured
over the period of monitoring, demonstrating their differing effects and the varying sensitivity and responsiveness of different
sites. The sporadic occurrence of flood events in such an environment means that a strategy of monitoring several sites and
of continuation over many years has great benefits. 相似文献

This paper presents a review of Australian urban riverine flooding. By world standards the Australian flood problem is relatively small, though there are pockets of development subject to regular severe inundation. In the past, government response to flooding was ad hoc and characterized by structural adjustments. The 1970s and 1980s, however, have seen a major shift in approach. The new approach emphasizes resource management rather than construction, and consists of the announcement of policies, enactment of enabling legislation, and the introduction of procedures to help ensure that the widest range of flood damage reduction measures are considered. The changes are evident at both the federal and state levels of government.
Though problems remain, particularly at the local government level, where ultimate responsibility for policy implementation generally rests, the authors feel there are good grounds for optimism. Some suggestions for future policy are offered and the importance of public safety is stressed. 相似文献

The occurrence of natural disasters, such as floods and earthquakes, are, in themselves, beyond oar control. However, careful preparation before such events, and the correct management of the problem once it occurs, can both lead to major redaction of the suffering involved.
Disaster preparation and emergency planning are both inextricably linked to politics and economics, both on a national and an international scale. Disasters themselves raise a number of issues of a political or economic nature, and die response to a natural disaster both in the short and the long term is largely determined by the political relations within a country, and between that country and the international community.
This paper examines these issues by taking the examples of the earthquake of Managua, Nicaragua in 1972 and the flooding that occurred in Nicaragua in 1982. These two natural disasters occurred under different administrations in Nicaragua, and tills allows some interesting comparisons. 相似文献

Weather, climate, and flood predictions are incorporated into human decisions in a wide variety of situations, including decisions related to hazardous hydrometeorological events. This article examines ethical aspects of such predictions and decisions, focusing on the case of the 1997 Red River flood in Grand Forks, North Dakota and East Grand Forks, Minnesota (US). The analysis employs a formal ethical framework and analytical method derived from medical and business ethics. The results of the analysis highlight issues related to forecast generation, communication of forecast meaning and uncertainty, responsibility for the use of forecasts in decision making, and trade-offs between the desire for forecast certainty and the risk of missed events. Implications of the analysis for the broader arenas of weather, climate, and flood prediction and disaster management are also discussed. 相似文献
