ABSTRACT.
– The Moldoviţa river basin is situated in the northern part of Eastern
Carpathians. It is a main right side tributary of Moldova river. The average
multi-annual flow recorded in Lunguleţ and Dragoşa hydrometric stations has the
value of 1.638 m3/s, and 5.099 m3/s, respectively. The last catastrophic floods
in Moldovita river basin occurred on 26th July 2008, with the high flood wave at
17:00. A maximum flow of 539 m3/s was recorded and a water level rise to 400m.
The high flood was devastating, damaging many houses and household attachments,
social and economic buildings. Over 20 ha of agricultural land were affected in
Vatra Moldoviţei. The waters flooded over 7 households in Valea Stânei village
and in Ciumârna, four gabions on the left river bank and 2 little bridges were
destroyed. In Vatra Moldoviţei village, 180 m of dam as well as a footbridge
were destroyed, and a wood deposit was flooded. In Paltinu village, the commune
road was 70% damaged, two bridges were severely affected, and the bridge defence
collapsed over a distance of 50 m. As a result of the anthropical intervention,
the catastrophic floods are more and more frequent.
