Taking the two typical tributaries in the loess plateau as an example, the hydrological effects of water and soil conservation measures were studied with parallel comparative analysis method. The results show that water and soil conservation measures can reduce annual runoff and sediment module, cut down flood peak discharge and lower sediment concentration efficiently. And meanwhile, it also c...

Although river dikes still play a key role for flood protection in the Netherlands there is a growing interest for other measures to deal with larger peak discharges, such as lowering or widening the floodplains. Regardless of the strategy chosen the assessment of its effect on the flood risk depends on the peak discharge statistics. A problem here is that the statistical analysis of peak disch...

introduction flood is a natural hazard that its occurrences can be observed more frequently in recent years. for better flood mitigation and control, it is needed to identify flood production factors and determine the high potential flood areas. hydrological model is a simplified representation of natural system and the rainfall-runoff model is one of the most frequently used events for flood s...

Statistical distributions of flood peak discharge often show heavy tail behavior, that is, extreme floods are more likely to occur than would be predicted by commonly used have exponential asymptotic behavior. This behavior may surprise managers and citizens, as human intuition tends expect light the heaviness tails is very difficult predict, which lead unnecessarily high damage. Despite its im...

(1) Snow melt period of December to April in combination with precipitation (typical of lowland and hilly parts of the Labe, Vltava and Morava catchments). (2) Longer duration of rainfall lasting 10 to 72 hours (rainfall intensified and prolonged by elevation enhancement). (3) Intensive short duration of summer rainfall exceeding (flood peak occurring within hours of rainfall peak, small areas ...

Extreme flood events in recent years in Canada have highlighted the need for historical information to better manage future flood risk. In this paper, a methodology to generate flood maps from Landsat to determine historical inundation frequency is presented for a region along the St-John River, New Brunswick, Canada that experiences annual springtime flooding from snowmelt and river ice. 1985–...

This paper examines the effects of urbanization on the flood hazard in semi-arid/arid southern California using traditional hydrograph, frequency-magnitude and statistical analysis augmented with GIS-based variable parameterizations and visualizations. It was found that the peak flood discharges were significantly increased in urban watersheds in conjunction with increasing mean baseflow in the...
