| Session Description | Hydrological processes are inherently stochastic and prediction and estimating their extremes are generally far more complicated than estimation of means. Extreme hydrological events, be it flood or drought, can cause devastating damages and thus modeling and estimating these extremes are of great importance. Extreme events do not occur frequently and thus hydrological extremes in large sample sizes are generally not available. Additionally, extraordinary extremes (outliers) can be observed even within a relatively short observation period. All these make modeling of extremes a difficult task. In this session, we invite presentations on modeling hydrological extremes, including theory, simulation and practical applications. Specific topics include, but are not limited to, the followings: 1. Extreme value theory 2. Collecting and modeling extreme series – Annual maximum/minimum, annual exceedance, peak-over-threshold, etc. 3. Goodness-of-fit tests of extremes 4. Parameter estimation 5. Dealing with smaller sample sizes (short record lengths) 6. How to deal with extraordinary outliers 7. Modeling spatial and temporal variations of extremes 8. Regional frequency analysis 9. Frequency analysis of multisite extreme events 10. Probable maximum precipitation |
