Jiang, Cong; Xiong, Lihua; Xu, Chong-Yu; Yan, Lei (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)In flood frequency analysis, expanding the additional information with hydrological reasoning beyond local at-site flood samples can be very useful for improving the accuracy of flood frequency distribution (FFD) estimation ...

Yan, Lei; Lu, Dongyang; Xiong, Lihua; Wang, Hongfeng; Luan, Qinghua; Jiang, Cong; Xiong, Bin; Xu, Wentao; Yan, Pengtao; Lei, Qingwen; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Urban infrastructure traditionally relies on stationary rainfall intensity-duration-frequency (IDF) curves. However, this assumption is challenged by climate change and urbanization. Many studies tried to update IDF using ...

Yan, Lei; Xiong, Lihua; Ruan, Gusong; Zhang, Mengjie; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract In traditional flood frequency analysis, a minimum of 30 observations is required to guarantee the accuracy of design results with an allowable uncertainty, however, there has not been a recommendation ...

Yan, Lei; Zhang, Liying; Xiong, Lihua; Yan, Pengtao; Jiang, Cong; Xu, Wentao; Xiong, Bin; Yu, Kunxia; Ma, Qiumei; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The fundamental assumption of flood frequency analysis is that flood samples are generated by the same flood generation mechanism (FGM). However, flood events are usually triggered by the interaction of meteorological ...

Yan, Lei; Xiong, Lihua; Luan, Qinghua; Jiang, Cong; Yu, Kunxia; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Given a changing environment, estimating a flood magnitude corresponding to a desired return period considering nonstationarity is crucial for hydrological engineering designs. Four nonstationary design methods, namely ...

Yan, Lei; Xiong, Lihua; Ruan, Gusong; Xu, Chong-Yu; Yan, Pengtao; Liu, Pan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The conventional flood frequency analysis typically assumes the annual maximum flood series (AMFS) result from a homogeneous flood population. However, actually AMFS are frequently generated by distinct flood generation ...

Yan, Lei; Xiong, Lihua; Jiang, Cong; Zhang, Mengjie; Wang, Dong; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)The intensity and frequency of extreme precipitation have increased in many regions in the past century due to climate change. Many studies have revealed that short-duration extreme precipitations are likely to become more ...
