Abstract:
The eastern part of Romania is frequently affected by floods. The flood regime in the Prut river catchment is
characterised by short, high intensity intensity rainfall, coupled with low infiltration in the soil, that lead to flash
floodings in the upland areas. The upper cathcment is controlled by the Stanca-Costesti reservoir that grately influences
the flow regime and decreseas significantly the flood risk for the downstream areas. Significant floods were recorded
during 2005 – 2020, with istoric maximum flows and total volumes. Through successive discharges of different
downstream flows, safe transit of volumes was achieved, without endangering downstream objectives. This paper
presents a comparative study of the maximum flows registered at the hydrometric stations and flood propagation times
between the succesive control sections. In order to maintain the safe operation of the defense lines on the Prut River (the
dykes), the personnel of Water Basinal Administration Prut – Barlad carried out immediate interventions at the critical
points highlighted on the embankment network (infiltrations, erosions, areas under the projected elevation, under
passages), depending on their seriousness and their negative effects. This paper can be used to further improve the
existing basinal flood defence plans.
