Bianca Otilia ADAM, Simion NACU
ABSTRACT. – Bacău County is located on both sides of Siret River in the central part of the river basin. Bacău County has a varied and picturesque land, having the Eastern Carpathians and the hills crossed by Bistriţa, Trotuş, Siret, Tazlău, Caşin and Slănic river valleys. The first part of this article contains the most important floods that happened in Bacau county. These were recorded in the following years: 1955,1969,1970, 1975,1991, 2005, 2008 and 2010. The exceptional flood that took place from 28-29 of July, 1991 on Tazlau River, produced the failure of Belci dam: The floods produced in 1991 destroyed 47 km of dikes and about 117 km of stream gradation, flooding causing the loss of 110 human lives. The flood between 12 of July and 17 of July, 2005 was the most important due to the maximum flow rates produced (the highest during the monitoring period) and due to its catastrophic flooding effects in the Trotuş river basin. The floods produced during the period 23.07-05.08.2008 in the northern half of the Siret river basin were, in most hydrometric stations, the largest in the entire monitoring period for over 60 years. At the Drăgeşti hydrometric station was recorded a maximum historical flow of 2930 mc / s. During the period 17.06-10.07.2010, in Bacău county were several floods on the main rivers due to the abundant rainfall that fell in the area, exceeding 100 l per sqm and reaching 189.9 l per sqm in Bacău, 239, 8 l per sqm in Goiasa and 258, 7 l per sqm in Scorţeni. During 2005-2019, a number of 23 towns were badly affected by the flood, registering over 10 events, the most affected being Moineşti with 15 events.
