Abstract: The reliability of the function and safety of hydraulic structures is often very markedly affected by winter conditions (ice acting on the structures, ice jams, clogging of the inlets by sludge, etc. ). Therefore statistical characteristics of ice phenomena and processes present frequently a considerable part of the operational reliability characteristics of the structures thus gaining a great significance. For the generalization and prediction in water management practice it is essential to investigate the stipulating and influencing time series of meteorological, climatic and hydrological characteristics such as temperature time series, wind conditions observation series, discharge series, series describing the occurrence and duration of the different ice phenomena and processes and series of values describing the intensity of the partaking ice phenomena and processes. The processing of the values obtained from the observations and measurements are not of the same standard and some of the partaking processes are not sufficiently known for the needs of the ice-engineering. The presented paper deals with some analysis results and determined statistical properties of some stipulating climatical and hydrological phenomena and data series of cryological parameters.
