The goal of this study is to develop an objective methodology for estimating design floods, i.e. the flood peak discharge with return period T , at ungauged river catchments in Iceland. First, a regional flood frequency analysis is presented for estimating the T -year flood peak discharge with fixed duration D, Q(T,D), for poorly gauged and ungauged catchments. This is done by scaling a regiona...

Two-third of the area of the Netherlands is flood prone. Storm surges at the North Sea, floods in the rivers, failure of secondary dikes, as well as heavy rainfall may cause flooding. Most of the flood prone areas rely for their existence on drainage by pumping, because their surface level may be permanently or during floods up to several metres below the surrounding water levels. During the pa...

A geospatial sensor web can be seen as a complex observation system consisting of distributed nodes with different functions and web-based access interfaces. Because of its heterogeneous characteristic, the precise discovery and efficient allocation of available nodes have become key problems in the field of sensor web resource integrated management. Considering the management requirements of a...

In this paper we present the data management tasks and tools used in a flood prediction application of the CROSSGRID project. The application consists of a computational core a cascade of three simulation stages, a workflow manager, two user interfaces and a data management suite. The project is based on the Grid technology, especially the Globus toolkit 2.4 and 3.2 and the EU DataGrid project....

Due to a number of recent high-profile flood events and the apparent threat from global warming, governments and their agencies are under pressure to make proactive investments to protect people living in floodplains. However, adopting a proactive approach as a universal strategy is not affordable. It has been argued that delaying expensive and essentially irreversible capital decisions could b...

The study of knowledge transfer is becoming important in many areas such as small-medium enterprises, higher education, health management and disaster management. Our study focuses on the process of knowledge transfer in the flood management domain in Malaysia. Currently, there is a lack of standard practice in terms of transferring knowledge between entities in this domain. Thus, based on a re...

Natural disasters such as floods and earthquakes impact many parts of Southeast Asia. In Malaysia, recent floods—such as those in 2014−2015—have caused untold damage to property and livelihoods. Up to that point, flood management had mainly emphasized disaster response, rather than risk-reduction strategies. The aim of this paper is to identify the local knowledge and practices of flood-affecte...

Flooding is a particular hazard in urban areas worldwide due to the increased risks to life and property in these regions. SAR sensors are often used to image flooding because of their all-weather day-night capability, and now possess sufficient resolution to image urban flooding. The flood extents extracted from the images may be used for flood relief management and improved urban flood inunda...

Flood risk reduction can be obtained in many ways and by many measures. A common approach in the Netherlands is to divide the measures into three layers: flood prevention, land-use planning and emergency management. An important question is how to divide the investment between these layers. In this paper we follow an economic approach: the selection of measures is guided by minimising the total...
