Zusammenfassung |
Moldova River is located in the east part of Eastern Carpathians, being tributary
of the Siret River, one of the biggest from Romania. Is 205 km long river with
discharge of about 32.8 m3/s (Roman hydrometric station), and drainage basin of 4316
km2.
In order to understand the river’s adjustments, we have analyzed the channel planform
behaviour and the controlling factors from a cause-effect perspective. On this line, we
accorded main importance to water-sediment system and it’s variability in the last 60
years.
In this study we have used four sets of topographic maps, with scales ranging
between 1910 and 2005, covering a period of nearly 100 years and also instrumental
measurements of discharge from 3 hydrometric stations along the river, covering the last six
decades.
The morphological changes of river channel bed were put in relation with the changes of
the water-sediment system in the analysed period by us. In the factor’s category that are
controlling these changes, we tried to distinguish the role of human factor. Thus, based on the
combination of the obtained data, we have found that the response of the Moldova
sediment system to anthropic forcing seems to be subsequent to the natural one. |
