Flood Frequency Quantification for Ungauged Sites using Continuous Simulation: a UK approach
The paper outlines recent and ongoing research addressing the quantification of river flood frequencies at ungauged sites across Britain. The approach is one of modelling continuous time series of catchment runoff. Model parameters are established where data permit: the spatial generalisation to ungauged sites is effected by relating model parameters to widely available catchment properties whi...

متن کاملA regional Bayesian POT model for flood frequency analysis
Flood Frequency Analysis is usually based on the fitting of an extreme value distribution to the series of local streamflow. However, when the local data series is short, frequency analysis results become unreliable. Regional frequency analysis is a convenient way to reduce the estimation uncertainty. In this work, we propose a regional Bayesian model for short record length sites. This model i...
متن کاملComparison of hybrid regression and multivariate regression in the regional flood frequency analysis: A case study in Khorasan Razavi province
Background: Magnitude, rate and frequency of the stochastic and unexpected events are of great significance and importance in hydrology. Nowadays, for economic planning of the projects, the use of analytical methods of unexpected events in hydrology is unavoidable. The aim of this study was to compare hybrid regression and multivariate regression to estimate flood peak discharge in the province...
متن کاملTransfer of Satellite Rainfall Uncertainty from Gauged to Ungauged Regions at Regional and Seasonal Time Scales
AU1 Hydrologists and other users need to know the uncertainty of the satellite rainfall datasets across the range of time–space scales over the whole domain of the dataset. Here, ‘‘uncertainty’’ refers to the general concept of the ‘‘deviation’’ of an estimate from the reference (or ground truth) where the deviation may be defined in multiple ways. This uncertainty information can provide insig...
