Distributed watershed models constitute a key component in flood forecasting systems. It is widely recognized that models because of their structural differences have varying capabilities of capturing...
Towards operational near real-time flood detection using a split-based automatic thresholding procedure on high resolution TerraSAR-X data
real-time flood detection split-based automatic thresholding procedure TerraSAR-X data
<
2009/12/16
In this paper, an automatic near-real time (NRT) flood detection approach is presented, which combines histogram thresholding and segmentation based classification, specifically oriented to the analys...

To support the transition from traditional flood defence strategies to a flood risk management approach at the basin scale in Europe, the EU has adopted a new Directive (2007/60/EC) at the end of 2007...
A contribution to improved flood magnitude estimation in base of palaeoflood record and climatic implications–Guadiana River(Iberian Peninsula)

2009/12/16
The Guadiana River has a significant record of historical floods, but the systematic data record is only 59 years. From layers left by ancient floods we know about we can add new data to the record, a...
Potential of historical meteorological and hydrological data for the reconstruction of historical flood events–the example of the 1882 flood in southwest Germany

This paper presents a hydrometeorological reconstruction of the flood triggering meteorological situation and the simulation of discharges of the flood event of December 1882 in the Neckar catchment i...
Rainfall thresholds and flood warning:an operative case study
Rainfall thresholds flood warning operative case study
<
2009/12/16
An operative methodology for rainfall thresholds definition is illustrated, in order to provide at critical river section optimal flood warnings. Threshold overcoming could produce a critical situatio...
This paper presents an assessment of normalised flood losses in Europe for the period 1970–2006. Normalisation provides an estimate of the losses that would occur if the floods from the past take plac...

Flood protection is one of the practical methods in damage reduction. Although it not possible to be completely protected from flood disaster but major part of damages can be reduced by mitigation pla...
Inundation scenarios for flood damage evaluation in polder areas
Inundation scenarios flood damage evaluation polder areas
<
2009/12/10
We present an approach for flood damage simulations through the creation of a comparatively large number of inundation scenarios for a polder area, using a high-resolution digital elevation model. In ...
Optimum multi-objective reservoir operation with emphasis on flood control and ecology

<
2009/12/10
The objective is to present a reservoir management system which is capable of determining optimal operating rules both for flood event based and normal operation while at the same time attempting to a...
Taking the heterogeneity of citizens into account:flood risk communication in coastal cities–a case study of Bremen

2009/12/10
The likely manifestations of climate change like flood hazards are prominent topics in public communication. This can be shown by media analysis and questionnaire data. However, in the case of flood r...
Flood history in the karst environment of Castellana-Grotte (Apulia, southern Italy)
Flood history the karst environment of Castellana-Grotte
<
2009/12/10
Karst environments are characterized by peculiar hydrologic features, and in particular by a very limited, if not absent, surface hydrography. Water tends to infiltrate rapidly underground through the...
