Analysis of the Hydroclimatic Risk Parameters at the High Level of the Tazlăul Sărat River in 2016 Year

Open access

Abstract

The paper presents an analysis of the hydrological risk parameters registered in June 2016 in the catchment area of the Tazlăul Sărat River. The studies and researches were carried out on the upper course of the river, in the area between Zemeş and Toderaş, the commune of Zemeş, Bacau county. The river basin of the Tazlăul Sărat River has been affected by several floods in recent years. The floods have morphologically modified the minor and the major river bed, which has influenced the stability of the county road and the river construction. The study focused on the analysis of precipitation and liquid flows over a period of 20 years. Processing of liquid flow data revealed more flood flows in the same year. In 2016 there was a flow of 342 m3 / s (probability of 3%). The effects of the floods have materialized through the excessive degradation of shore defence works until their total destruction. The degradation of shore defence works has contributed to breaking the county road and limiting the road traffic. Parameters of hydroclimatic risk highlighted by research impose special conditions when designing shore defence works and protecting the road adjacent to the river.
