Exceptional flood events in the summer of 2018 in Trebes Negel Reprezentativ bazin (Romania)

In the summer of 2018, the general unstable weather throughout the central and eastern parts of Romania has led to significant rainfall, sometimes exceeding 60 mm/day, and consequently to a massive runoff on the slopes that rapidly increased the flow on tributaries and the main course of the river Trebes from the Moldavian Subcarpathians. The majority of the hydrometric basin stations recorded exceeded caution levels, and the hydrometric station Bacau registered the maximum historical level (H= 348 cm). Analysis and data processing were performed using programs and hydraulic calculations for different probabilities that demonstrated this.
