This session is sponsored by the Statistics in Hydrology Working Group (STAHY-WG) of International Association of Hydrological Science (IAHS). It aims to explore methods for univariate and multivariate statistical analysis of hydrological variables (extreme values, inference procedure, copula functions) including stochastic modelling (linear and non-linear models, space-time simulation procedures, time series analysis, point processes). Presentations and poster contributions focusing on new theories and hydrological applications are particularly encouraged.
