A probabilistic view on the August 2005 floods in the upper Rhine catchment
A probabilistic view the August 2005 floods the upper Rhine catchment
2009/12/30
Appropriate precautions in the case of flood occurrence often require long lead times (several days) in hydrological forecasting. This in turn implies large uncertainties that are mainly inherited fro...
Ensemble prediction of floods – catchment non-linearity and forecast probabilities
Ensemble prediction floods catchment non-linearity forecast probabilities
2009/12/30
Quantifying the uncertainty of flood forecasts by ensemble methods is becoming increasingly important for operational purposes. The aim of this paper is to examine how the ensemble distribution of pre...
Risk assessment and mapping of extreme floods in non-dyked communities along the Elbe and Mulde Rivers
Risk assessment mapping of extreme floods non-dyked communities the Elbe and Mulde Rivers
2010/1/26
Assessing and mapping damage risk of floods for large river basins is still in its infancy. Damage risk is understood to be the combination of flood hazard and the vulnerability of communities to a fl...
The use of radar in hydrological modeling in the Czech Republic–case studies of flash floods
radar hydrological modeling Czech Republic flash floods
2009/12/29
Flash flood induced by severe convection is the hydrometeorological phenomenon that is very difficult to forecast. However, the implementation of radar measurements, especially radar-based Quantitativ...
Karst flash floods:an example from the Dinaric karst (Croatia)
Karst flash floods an example Dinaric karst
2009/12/29
Flash floods constitute one of the deadliest and costliest natural disasters worldwide. This paper explains the karst flash flood phenomenon, which represents a special kind of flash flood. As the maj...
The variation of floods in the middle reaches of the Yangtze River and its teleconnection with El Niño events
floods the Yangtze River teleconnection El Niñ o events
2010/1/25
Middle reaches of the Yangtze River are the worst flooded segments along the Yangtze River. It is important to understand and study the variations of frequency and magnitude of historical floods in th...
Model system development and uncertainty for the provisionary management of extreme floods in large river basins
Model system development uncertainty provisionary management extreme floods
2010/1/25
A research project is introduced in which a modelling system is being developed to quantify risks of extreme flooding in large river basins. In the system, computer models and modules are coupled to s...
Use of historical data to assess the occurrence of floods in small watersheds in the French Mediterranean area
historical data the occurrence of floods small watersheds the French Mediterranean area
2010/1/22
The results of an investigation on historical floods in four watersheds of the Aude region in France are presented herein. Using both, archive documents and field investigations, the discharges of the...
In this paper the catastrophic and extraordinary floods occurring in Barcelona County (Catalonia, NE Spain) are studied, in order to characterise the temporal evolution of extreme flash floods in that...
Floods can cause large interannual differences in littoral net ecosystem productivity
interannual differences littoral net ecosystem productivity
2014/5/19
Littoral wetlands comprise a terrestrial to aquatic continuum along which carbon dioxide is exchanged with the
atmosphere and organic carbon is transferred to lakes. Net ecosystem productivity—the di...
