A Bivariate Extreme Value Distribution Applied to Flood Frequency Analysis
Bivariate Extreme Value Distribution Flood Frequency Analysis
<
2009/10/23
This article presents a procedure for use of the Gumbel logistic model to represent
the joint distribution of two correlated extreme events. Parameters of the
distribution are estimated using the me...
Threshold effects in catchment storm response and the occurrence and magnitude of flood events：implications for flood frequency
catchment storage flood frequency flood
<
2009/5/12
The aim of this paper is to illustrate the effects of selected catchment storage thresholds upon runoff behaviour, and specifically their impact upon flood frequency. The analysis is carried out with ...

flood frequency flood generation process
<
2009/5/12
Traditional statistical approaches to flood frequency inherently assume homogeneity and stationarity in the flood generation process. This study illustrates the impact of heterogeneity associated wit...

A space-time hybrid hourly rainfall model for derived flood frequency analysis
hourly rainfall model flood frequency analysis
<
2009/5/6
For derived flood frequency analysis based on hydrological modelling long continuous precipitation time series with high temporal resolution are needed. Often, the observation network with recording r...
In general, different mechanisms may be identified as responsible of runoff generation during ordinary events or extraordinary events at the basin scale. In a simplified scheme these mechanisms may be...
Strong increases in flood frequency and discharge of the River Meuse over the late Holocene：impacts of long-term anthropogenic land use change and climate variability
high-flow climatic change
<
2009/4/28
In recent years the frequency of high-flow events on the Meuse (northwest Europe) has been relatively great, and flooding has become a major research theme. To date, research has focused on observed d...
Climatic and basin factors affecting the flood frequency curve: PART II – A full sensitivity analysis based on the continuous simulation approach combined with a factorial experimental design
Monte Carlo simulation factorial experimental design
<
2009/3/24
The sensitivity analysis described in Hashemi et al. (2000) is based on one-at-a-time perturbations to the model parameters. This type of analysis cannot highlight the presence of parameter interactio...

<
2009/3/24
Regionalized and at-site flood frequency curves exhibit considerable variability in their shapes, but the factors controlling the variability (other than sampling effects) are not well understood. An ...
