Flood frequency analysis supported by the largest historical flood [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2014
The use of non-systematic flood data for statistical purposes depends on the reliability of the assessment of both flood magnitudes and their return period. The earliest known extreme flood year is usually the beginning of the historical record.

Flood frequency analysis of historical flood data under stationary and non-stationary modelling [PDF]

open access: yesHydrology and Earth System Sciences, 2015
Historical records are an important source of information on extreme and rare floods and fundamental to establish a reliable flood return frequency.

Regional analysis of runoff thresholds behaviour in Southern Italy based on theoretically derived distributions [PDF]

open access: yesAdvances in Geosciences, 2011
The analysis of runoff thresholds and, more in general, the identification of main mechanisms of runoff generation controlling the flood frequency distribution is investigated, by means of theoretically derived flood frequency distributions, in the ...

Comparative analysis of routed flood frequency for reservoirs in parallel incorporating bivariate flood frequency and reservoir operation

open access: yesJournal of Flood Risk Management, 2021
Flood frequency is commonly defined by natural flood characteristics such as flood peak, volume and duration. However, for floods at reservoir site, reservoir operation will significantly alter the natural flood process and flood frequency.

A conceptual investigation of process controls upon flood frequency: role of thresholds [PDF]

open access: yesHydrology and Earth System Sciences, 2007
Traditional statistical approaches to flood frequency inherently assume homogeneity and stationarity in the flood generation process. This study illustrates the impact of heterogeneity associated with threshold non-linearities in the storage-discharge ...

Climate change impacts on summer flood frequencies in two mountainous catchments in China and Switzerland

open access: yesHydrology Research, 2021
Flood events are difficult to characterize if available observation records are shorter than the recurrence intervals, and the non-stationarity of the climate adds additional uncertainty.

Climate, orography and scale controls on flood frequency in Triveneto (Italy) [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2016
The growing concern about the possible effects of climate change on flood frequency regime is leading Authorities to review previously proposed reference procedures for design-flood estimation, such as national flood frequency models.

Hydrological characteristics of extreme floods in the Klaserie River, a headwater stream in southern Africa

open access: yesJournal of Limnology, 2023
Climate change models for southern Africa predict less frequent, but more intense, rainfall events, and an increased frequency of tropical cyclones.

Analysis of Biweekly Oscillation and Low-Frequency Circulation Characteristics of Summer Precipitation in Drought-Flood Years over the Qinghai-Xizang Plateau

open access: yesGaoyuan qixiang, 2023
In order to study the characteristics of low frequency oscillation of summer precipitation over Qinghai-Xizang Plateau, based on the daily precipitation data of 62 meteorological stations over the Qinghai-Xizang Plateau from 1978 to 2017 and the high ...
