K. Konecsny , Z. Nagy
ABSTRACT. – Main hydrological statistical characteristics of low water and
high water on the Tur/Túr stream. The Tur/Túr river network (1261 km2) is
the secondary left bank tributary of Tisa. The catchment is shared by Romania
(96%) and Hungary (4%). Daily streamflow data for the description of low flow
conditions are available since 1961, namely 49 years long series for
Negreşti-Oaş, Turulung (RO) and Garbolc (HU) consequently. Lower reaches of the
river were considerable modified during the 19th and 20th century river training
and flood protection works including the topology and geometry of channel
network, while the hydrological regime of the upper hilly and undulating regions
remained nearly natural until 1972. Discharge series until 1973 are or only
slightly influenced, while the impact of reservoir Călineşti-Oaş the temporal
distribution of runoff is felt after that period.
Key words: minimum and maximum discharge, low flow periods, high flow
periods, hydrological statistical analysis, water uses, discharge values
probabilities.
