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...

The purpose of this article is to examine major interrelated issues that are present in current discussions about the biblical Flood narrative of Gen 6-9. These include such questions as: the unity and literary genre of these chapters, the nature and extent of the biblical Flood, the relationship between history and theology in the Flood narrative, and the relationship of the biblical Flood nar...

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. One of the major tasks which member states must carry out in order to comply with this Directive is to map flood hazards and risks in their territory, which will form the basis of future flood ri...

Bankfull discharge estimation is a crucial step in river basin management. Such evaluation can be carried out using hydrological and hydraulic modelling to estimate flow-depths, flow velocities flood prone areas related specific return period. However, different methodological approaches are described the scientific literature. typically based either on assumption that bankfull corresponds narr...

The morphostratigraphy of flood plains along unconfined reaches of the Todd River, central Australia, indicate that flood plain formation is dominated by high magnitude floods. Processes of flood plain destruction include channel widening, vertical stripping, flood channel, back channel and macroturbulent scour. Flood plain construction occurs predominantly during high magnitude floods. Overban...

The disparate spatial and temporal distribution of rainfall in the country and climate variation sometimes leads to rivers flooding and large flood events, which are remarkable for life and financial losses. Flood control design requires accurate knowledge of the flood generator basin, especially smaller ones, in large basins. Determining the potential of flood generation to specify the...

Flooding in general is insignificant event worldwide and also in Thailand. The Central plain, the Northern plain and the northeast of Thailand are frequently flooded areas, caused by yearly monsoons. The Thai government has extra expenditure to provide disaster relief and for the restoration of flood affected structures, persons, livestock, etc. Current flood detection in real time or near real...

r Publis .030 : +1 413 mass.ed Summary Flood routing processes in the middle Yellow River basin are complex since they consist of three types of flood: bidirectional, convergent and divergent flood flows between the main channel and its tributaries. We propose three computation schemes to simulate the complex flood routing: a simple scheme for a single main channel with no tributary or backwate...

Outburst floods resulting from giant landslide dams can cause devastating damage to hundreds or thousands of kilometres a river. Accurate and timely delineation flood inundated areas is essential for disaster assessment mitigation. There have been significant advances in mapping using remote sensing images recent years, but little attention has devoted outburst mapping. The short-duration natur...

Of all natural disasters, flooding causes the greatest amount of economic and social damage. The United States' Federal Emergency Management Agency (FEMA) uses a number of hazard mitigation grant programmes for flood victims, including mitigation offers to relocate permanently repetitive flood loss victims. This study examines factors that help to explain the degree of difficulty repetitive flo...
