This paper presents the development and application of a three-dimensional numerical model for simulating the flow field and pollutant transport in a flood zone near the confluence of the Mississippi River and Iowa River during the US Midwest Flood in 2008. Due to a prolonged precipitation event, a levee along the Iowa River just upstream of Oakville, Iowa broke, and the small town was complete...

This paper identifies groups vulnerable to the effect of flooding on hospital visits due to diarrhoea during and after a flood event in 1998 in Dhaka, Bangladesh. The number of observed cases of cholera and non-cholera diarrhoea per week was compared to expected normal numbers during the flood and post-flood periods, obtained as the season-specific average over the two preceding and subsequent ...

r a 200 .021 : +886 2 ail.tku.e Summary Real-time flood control of a multi-purpose reservoir should consider decreasing the flood peak stage downstream and storing floodwaters for future usage during typhoon seasons. This study proposes a reservoir flood control optimization model with linguistic description of requirements and existing regulations for rational operating decisions. The approach...

This paper present recent achievements obtained within the context of the ANFAS project (Data fusion for flood simulation and decision support). The overal objective of ANFAS was to set up an integrated system for flood prevention and protection. Data fusion and models fusion techniques constitute the core of the scientific research work of the project. Data fusion refers to the use of multi-so...

A high-resolution sedimentological and geochemical study of a high-altitude proglacial lake (Lake Blanc, Aiguilles Rouges, 2352m a.s.l.) revealed 195 turbidites, 190 of which are related to flood events over the last 1400 years. We used the coarsest sediment fraction of each turbidite as a proxy for the intensity of each flood event. Because most flood events at this locality are triggered by l...

Global warming is currently of great concern. Yet the ecological effects of low-frequency climate variations remain largely unknown. Recent analyses of interdecadal variability in population abundance of the Oriental migratory locust (Locusta migratoria manilensis) in China have revealed negative associations with temperature and positive associations with Yangtze drought and flood frequencies ...

Protecting our water resources in terms of quality and quantity is considered one of the big challenges of the twenty-first century, which requires global and multidisciplinary solutions. A specific threat to water resources, in particular, is the increased occurrence and frequency of flood events due to climate change which has significant environmental and socioeconomic impacts. In addition t...

Flood disaster is one of the natural disasters those have the highest occurrence frequency. Remote sensing plays an active and important role in the flood disaster management such as monitoring, evaluation, emergency response and so on. Affected by the characteristics of flood disaster, emergency response for flood disaster must be guaranteed by a high quality and speedy remote sensing data res...

Among various natural disasters floods make the largest impact in terms of number of casualties, people affected and property lost. Flood data during the past 30 years show that flood events that cause significant impacts have increased at a steady rate. Available data suggest that this increase could be attributed to increasing population and exposure, increasing property values located in vul...

1. introduction flood is one of natural hazard which ranks the most one just like earthquake and drought according to the report of the natural hazard program of the united nations. besides physical factors, and lack proper management will increase the flood potential. therefore, in order to prevent flood damage it seems to be necessary to provide essential requirements before physical expansio...
