| Zusammenfassung |
| Flash-flood disasters are very rare in the Transylvanian Depression. In the
last decades just three events were signalled in the study area, all of them
during the last 10 years. The flash floods occurring in the study area during
the last decade had a significant impact on several localities situated at
the Transylvanian Depression border. Based on the post flash-flood
investigation, the present study intends to find out the main characteristics
of the flash floods and the causes that have led to disasters in a region
rarely affected by such kinds of events. Analyzing the hydrological data, it
has been seen that the maximum intensity of the flash floods was observed in
the upper and middle basins. By comparing the unit peak discharges from the
studied region with other specific peak discharges related to the significant
flash floods from Romania, it was noticed that the events from the
Transylvanian Depression have moderate to low intensity. On the other hand,
the results showed that besides high stream power and unexpected character
common to flash floods, the inappropriate flood risk management measures
increased the dimension of the negative effects, leading to tens of lives
lost and economical damages of tens of millions of dollars. |
