Dynamika transportu fluwialnego górnej Parsêty jako odbicie funkcjonowania systemu zlewni
Dynamics of fluvial transport of the upper Parsêta River as a response of the catchment system
In the contemporary denudation system of West Pomerania, fluvial transport plays a fundamental role in carrying away material from erosion and denudation in a catchment. A detailed analysis of fluvial transport allows it to be recognised as an indicator of relief evolution, including soil leaching and erosion. In the present study, the object of investigation was the upper ParsÍta catchment, which was judged representative of the young-glacial zone of West Pomerania and for the Polish Plain. Systematic investigations of modern morphogenetic processes in the upper ParsÍta catchment have been carried out since 1981. Since 1 November 1985, daily measurements have been taken in the profile closing the upper ParsÍta catchment (at Storkowo), which is treated as an independent denudation system. The basic aims of the present article include:
- a description of the controls, pattern and intensity of fluvial transport, which are reflections of the denudation processes occurring in the upper ParsÍta catchment system, i.e. mainly soil erosion and leaching,
- establishing variations in the upper ParsÍta's regime,
- a description of variations in the physical-chemical properties of solutes and solids in the upper ParsÍta channel as factors controlling the variability of fluvial transport and determining its role in the contemporary denudation system of the catchment,
- the presentation of a multi-parametric predictive model of river load carried away from the upper ParsÍta catchment.
