River flow extremes constitute a complex random process in both space and time. In this paper, some basic characteristics of flood flows considered as a spatial process are reviewed and discussed. Of particular interest are both marginal and joint distributional properties of annual peak flows at a collection of points in some large region. Two widely used regionalization methods for modeling t...

Almost two centuries of human interventions at the Upper Rhine to adapt the river systems to led to a serious increase of the flood risk and potential damage downstream. In 1982, the two riparian countries, Germany and France, agreed to re-establish the former protection level against a once-in-200-years flood, with Germany taking most of the workload. This can be considered as the starting poi...

One of the major unresolved issues of the Late Pleistocene catastrophic-flood events in the northwestern United States (e.g., from glacial Lake Missoula) has been what happened when the flood discharge reached the ocean. This study compiles available 3.5-kHz high-resolution and airgun seismic reflection data, long-range sidescan sonar images, and sediment core data to define the distribution of...

Flood simulation models and hazard maps are only as good as the underlying data against which they are calibrated and tested. However, extreme flood events are by definition rare, so the observational data of flood inundation extent are limited in both quality and quantity. The relative importance of these observational uncertainties has increased now that computing power and accurate lidar sca...

UNLABELLED Lymphoscintigraphy uses intradermal or interstitial injections of (99m)Tc-labeled tracers to produce images of focal lymph nodes. Because there is little or no anatomic information in the (99m)Tc images, a (57)Co flood source is sometimes used to provide transmission data along with the emission data. The anatomic shadow from the transmission scan generally improves interpretation an...

The problem of computing risk measures associated to flood events is extremely important not only from the point of view of civil protection systems but also because of the necessity for the municipalities of insuring against the damages. In this work we propose, in the framework of an integrated strategy, an operating solution which merges in a conditional approach the information usually avai...

Biodiversity declined markedly over the past 150 years, with the biodiversity loss in fluvial ecosystems exceeding the global average. River restoration now aims at flood safety while enhancing biodiversity and has had success locally. However, at the scale of large river distributaries, the recovery remained elusive. We quantify changes in biodiversity of protected and endangered species over ...

In June/July 2009 the weather in the Czech Republic was influenced by a 12 days lasting baric low located over Mediterranean, which resulted in a sequence of many flash foods. The total damage was estimated to be about 200 mil. EUR and 15 people died. Although the flash flood is considered as hardly predictable phenomena, first efforts in flash floods forecasting have been already done [1]. Som...

Aim of this paper is to investigate the application of cost benefit analysis methods in the decisionmaking on a desired flood protection strategy in the Netherlands. After a discussion of historical developments in flood protection in the Netherlands the method of cost benefit analysis is presented as a useful instrument in decision-making. In the second part of the paper the economic analysis ...

Distributed denial-of-service (DDoS) flood attack remains great threats to the Internet. This kind of attack consumes a large amount of network bandwidth or occupies network equipment resources by flooding them with packets from the machines distributed all over the world. To ensure the network usability and reliability, real-time and accurate detection of these attacks is critical. To date, va...
