Hydrological Extremes in a Changing Environment: Modelling and Attribution Analysis
Hydrological extremes, i.e. droughts and floods, are globally important natural hazards with associated costly impacts on society and the environment. Floods and droughts result from the superposition of different processes at various space and time scales: physical processes in the atmosphere, catchments, the river systems and anthropogenic activities. However, the characteristics of hydrological extremes have been altered due to climate change and variability, such that approaches for their detection, attribution and frequency of occurrence need to be revisited as they are no longer stationary processes. For more accurate estimation of hydrological extremes under nonstationary and uncertain conditions, there is a need for holistic assessments. Time-frequency analysis, hydrological modeling, physical-cause analysis, multivariate statistical analysis and uncertainty analysis are powerful tools for detecting, attributing and making frequency analysis of nonstationary hydrological extremes in a changing climate. Both non-stationarity and uncertainty of frequency analysis of extreme hydrological events should be integrated to reveal the possible operational alternatives to the assumption of stationarity in hydrological extremes frequency analysis. This Special Issue aims to promote innovative research advances in the detection, attribution and frequency analysis of nonstationary hydrological extremes through novel techniques.
