Sažetak
Bistriţa is the river with the longest mountainous sector in Romania, two thirds of its course passing through the Eastern Carpathians. The paper analyzes the most frequent hydrologic and meteorological phenomena with negative consequences from Bistrita valley (extreme
temperatures, torrential rainfall, violent storms, winter phenomena etc.), whose frequency has significantly increased during the last decades. Data from meteorological stations and rainfall gauges in the area were used, as well as references considering the factors influencing the occurrence and evolution of risk phenomena. The study also analyzes some of the most important climate and hydrological hazards and risks that have occurred along Bistriţa
valley and on some of its tributaries during the last decades, and attempts to establish the peculiar characteristics of the ice jams on Bistriţa and Bistricioara and the causes that have led to the formation in the 1972-1973 winter on Bistriţa of an ice jam considered unique in Romania and even Europe, as well as of solutions to substantially diminish the effects of these phenomena.
