Mountain floods ¿ regional joint probability estimation of extreme events - ISDR

01.09.2008 - 31.07.2016
Research funding project
This project analyses the probabilistic characteristics of floods in a regional context to provide insight into the causal factors. Dependence models (copulas) are used to represent the joint probabilities of flood characteristics, specifically, the dependence between flood peak and flood volume, and the dependence between flood flows at the tributaries and the main stem of river confluences. Synthetic runoff time series are generated to identify the most suitable copula functions and parameters, which are tested against flood data of numerous catchments in Slovakia and Austria. The overall outcomes of this project are a better understanding of the nature of dependence as a function of flood magnitude, its causal controls and its spatial and temporal variability. These new insights are the basis for more accurate extrapolations to extreme events and to ungauged locations than is possible with standard methods.
