BACKGROUND AND AIMS Reducing damage to rice seedlings caused by flash flooding will improve the productivity of rainfed lowland rice in West Africa. Accordingly, the morphological and physiological responses of different forms of rice to complete submergence were examined in field and pot experiments to identify primary causes of damage. METHODS To characterize the physiological responses, se...

v To all those who have pushed me, pulled me, taught me, and challenged me. vi " Though the rain comes in torrents and the floodwaters rise and the winds beat against that house, it won't collapse because it is built on bedrock. " − Jesus Christ, Matthew 7:25 (New Living Translation) vii ACKNOWLEDGEMENTS First, I want to note that I worked with Dr. Michael Marder and Dr. Pradeep Raviku-mar at U...

AVS in collaboration with Linkoping University are developing a Visual User Interface and Web-enabled advanced 3D visualization to a flood forecasting system in an EC funded project named MUSIC. The project develops state-ofthe-art precipitation estimation algorithms, assess their uncertainty and use an innovative combination of the output data of the three independent data sources radar, satel...

During the evacuation process, the most challenging task is to move people to safer locations. As time is the decision factor in the evacuation process, urgent and firmly decisions are required. An evacuation plan should be efficiently constructed by taking into account the routes of vehicle. This paper explored the feasibility of using a discrete particle swarm optimization (DPSO) algorithm to...

Flood forecasts are essential to issue reliable flood warnings and to initiate flood control measures on time. The accuracy and the lead time of the predictions for head waters primarily depend on the meteorological forecasts. Ensemble forecasts are a means of framing the uncertainty of the potential future development of the hydro-meteorological situation. This contribution presents a flood ma...

Affected locations by flash floods are rich in information for flood management. Usually, there are several types and sources of information which can be related to achieve better reliability to decision-making. However, a major challenge is to achieve the reliability this information within datasets so heterogeneous or complex. For instance, reports of Volunteered Geographic Information (VGI) ...

Flood waves resulting from dam breaks and flash floods have been responsible for numerous losses. In the present study, sudden flood releases were investigated down a large flume with a succession of abrupt drops. A new experimental technique was developed to obtain instantaneous void fractions, bubble count rates and velocities using arrays of conductivity probes. The results showed the surge ...

Flash flood risk management is among the key topics of European Flood Directive. Design hydrographs small river basins could underestimate hydraulic in case intense and short-duration events because intensification hourly rainfall design depths uncertainty often ungauged basins. The use synthetic hyetographs obtained from past observed can be useful for a better evaluation flash hazard at basin...
