The paper examines the flash floods that may appear in a representative river
basin occupying the south-western Romania and also feature an example of the
most recent flash flood from 2005-2006, more specifically, its causes and
consequences. In order to accomplish the objectives, hydrological data were
used to identify the characteristics of the floods. Finally, the case study
of the flash flood was delivered through the field research, observational
method, discussion with the authorities and investigation of the
meteorological and hydrological available data. The research offers an
insight on the dimension of damages triggered by a flash flood event, based
on the statistical data provided by the village hall and the few remaining
places preserving the traces of the floods (houses, bridges). Because we
could not provide all the necessary data in order to determine the frequency
and scale of such risk phenomena, the analysis is assessed on general
hydrological statistics of flood events between 1964 to 2011. By leading the
research, it resulted that the specific feature of the upper basin of
Desnatui River is its temporary drainage and that in the periods of high
flow, the capacity of the river channels is diminshed and the floods may
occur. The paper succeeds to revive the insufficient scientific concerns on
this kind of hydrological risks issued in the space occupied by the upper
basin of Desnatui River and eventually, to supply the need for such study in
the context of modern hydrological research preoccupations
