Selected AbstractsNutritional Response to the 1998 Bangladesh Flood Disaster: Sphere Minimum Standards in Disaster ResponseDISASTERS, Issue 3 2002Max R. O'Donnell In this study we use a cross,sectional survey to evaluate the nutritional response to the 1998 Bangladesh Flood Disaster by 15 relief agencies using standards developed by the Sphere Project. The Sphere Project is a recent attempt by agencies around the world to establish universal minimum standards for the purpose of ensuring quality and accountability in disaster response. The main outcomes measured were resources allocated to disaster relief, types of relief activities and percentage of agencies meeting selected Sphere food aid and nutrition indicators. Although the process of nutritional response was measured, specific nutritional and health outcomes were not assessed. This review found that self,reported disaster and nutritional resources varied widely between implementing agencies, ranging from US$58,947 to $15,908,712. The percentage of resources these agencies allocated to food aid and nutritional response also varied, ranging from approximately 6 to 99 per cent of total resources. Agencies met between 8 and 83 per cent of the specific Sphere indicators which were assessed. Areas in which performance was poor included preliminary nutritional analysis; beneficiary participation and feedback; disaster preparedness during non,emergency times; monitoring of local markets and impact assessment. Agencies were generally successful in areas of core humanitarian response, such as targeting the vulnerable (83 per cent) and monitoring and evaluating the process of disaster response (75 per cent). The results here identify both strengths and gaps in the quality of humanitarian response in developing nations such as Bangladesh. However, they also raise the question of implementing a rights,based approach to disaster response in nations without a commitment to meeting positive human rights in non,disaster times. [source] Flood Disasters and Agricultural Wages in BangladeshDEVELOPMENT AND CHANGE, Issue 4 2007Lopamudra Banerjee ABSTRACT This article examines the effects of abnormal floods on agricultural wages in Bangladesh. Drawing upon the district-wise monthly real wage data for the period 1979,2000, it shows that wages decline sharply in the regions that are severely inundated for a long period of time. Wages may remain depressed in these regions even in the post-flood months. However, wages increase in the flood months in the regions that remain submerged for short durations. The article examines the district-wise crop yield data to explain these results in terms of the impact of flood on agricultural productivity, and therefore the demand for labour. [source] A HYDROCLIMATOLOGICAL ANALYSIS OF THE RED RWER OF THE NORTH SNOWMELT FLOOD CATASTROPHE OF 1997,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 5 2001Paul E. Todhunter ABSTRACT: The flood hydroclimatology of the Grand Forks flood of April 1997, the most costly flood on a per capita basis for a major metropolitan area in United States history, is analyzed in terms of the natural processes that control spring snowmelt flooding in the region. The geomorphological characteristics of the basin are reviewed, and an integrated assessment of the hydroclimatological conditions during the winter of 1996 to 1997 is presented to gain a real-world understanding of the physical basis of this catastrophic flood event. The Grand Forks flood resulted from the principal flood-producing factors occurring at either historic or extreme levels, or at levels conducive to severe flooding. Above normal fall precipitation increased the fall soil moisture storage and reduced the spring soil moisture storage potential. A concrete frost layer developed that effectively reduced the soil infiltration capacity to zero. Record snowfall totals and snow cover depths occurred across the basin because of the unusual persistence of a blocking high circulation pattern throughout the winter. A severe, late spring blizzard delayed the snowmelt season and replenished the snow cover to record levels for early April. This blizzard was followed by a sudden transition to an extreme late season thaw due to the abrupt breakdown of the blocking circulation pattern. The presence of river ice contributed to backwater effects and affected the timing of tributary inflows to the main stem of the Red River. Only the absence of spring rains prevented an even more catastrophic flood disaster from taking place. This paper contributes to our understanding of the flood hydroclimatology of catastrophic flood events in an unusual flood hazard region that possesses relatively flat terrain, a north-flowing river, and an annual peak discharge time series dominated by spring snowmelt floods. [source] Marginalization, Facilitation, and the Production of Unequal Risk: The 2006,Paso del Norte,FloodsANTIPODE, Issue 2 2010Timothy W. Collins Abstract:, Drawing upon insights from the field of urban political ecology, this article extends the critical hazards concept of,marginalization,by incorporating a relational focus on,facilitation. Facilitation connotes the institutionally mediated process that enables powerful geographical groups of people to minimize negative environmental externalities and appropriate positive environmental externalities in particular places, with unjust socioenvironmental consequences. The article demonstrates the utility of a marginalization/facilitation frame for understanding the production of unequal risk based on a case study of the 2006 El Paso (USA)-Ciudad Juárez (Mexico) flood disaster. The case study reveals how uneven developments have produced complex sociospatial patterns of exposure to flood hazards and how processes of facilitation and marginalization have created socially disparate flood-prone landscapes characterized by unequal risks. The paper concludes by outlining how the frame presented helps clarify understanding of the production of unequal risk. [source] Effect of growing watershed imperviousness on hydrograph parameters and peak dischargeHYDROLOGICAL PROCESSES, Issue 13 2008Huang-jia Huang Abstract An increasing impervious area is quickly extending over the Wu-Tu watershed due to the endless demands of the people. Generally, impervious paving is a major result of urbanization and more recently has had the potential to produce more enormous flood disasters than those of the past. In this study, 40 available rainfall,runoff events were chosen to calibrate the applicable parameters of the models and to determine the relationships between the impervious surfaces and the calibrated parameters. Model inputs came from the outcomes of the block kriging method and the non-linear programming method. In the optimal process, the shuffled complex evolution method and three criteria were applied to compare the observed and simulated hydrographs. The tendencies of the variations of the parameters with their corresponding imperviousness were established through regression analysis. Ten cases were used to examine the established equations of the parameters and impervious covers. Finally, the design flood routines of various return periods were furnished through use of approaches containing a design storm, block kriging, the SCS model, and a rainfall-runoff model with established functional relationships. These simulated flood hydrographs were used to compare and understand the past, present, and future hydrological conditions of the watershed studied. In the research results, the time to peak of flood hydrographs for various storms was diminished approximately from 11 h to 6 h in different decrements, whereas peak flow increased respectively from 127 m3 s,1 to 629 m3 s,1 for different storm intensities. In addition, this study provides a design diagram for the peak flow ratio to help engineers and designers to construct hydraulic structures efficiently and prevent possible damage to human life and property.

[source] Japan's strategic contributions to hydro-meteorological disaster mitigation in the world: planning to establish the UNESCO,PWRI CentreHYDROLOGICAL PROCESSES, Issue 6 2006Tetsuya Ikeda Hydro-meteorological disasters such as floods are major challenges that need to be overcome in order to realize sustainable development and poverty alleviation for humankind. Devastating flood disasters have occurring in various locations throughout the world, and there has recently been rising concern that the intensity and frequency of catastrophic floods may be increasing. Being located on the eastern edge of monsoonal Asia and having climatic variations according to the seasonal and regional conditions, Japan has long suffered from numerous flood disasters, and thus has developed advanced flood management policies. This paper aims to discuss flood disasters in Japan and the recently improved flood management policies. In addition, this paper introduces a new plan attempted by the Public Works Research Institute (PWRI) of Japan that takes advantage of the wealth of long accumulated experience and knowledge in the hydro-meteorological field. The PWRI is now working toward the establishment of an International Centre on Water-related Hazard and Risk Management by acquiring UNESCO's auspices. In order to contribute to the global challenge of reducing devastating hydro-meteorological disasters all over the world, this centre aims to conduct research, capacity-building and training programmes, and information networking activities at the local, national, regional and global levels. The aim is to prevent and mitigate hydro-meteorological disasters from the viewpoint of sustainable and integrated river basin management. Copyright © 2006 John Wiley & Sons, Ltd.
