摘要：Flood plains are a specific sedimentary environment.They are a natural clarifier and filter for rivers carrying large amounts of heavy metals, biogenic elements and other contaminants transported during high water and floods.Plenty of it is accumulated in the riverbank zone of channels i.e.a buffer strip.This is a relatively narrow strip of land situated along watercourses, often covered with riparian plants.It is functionally associated with river flooding and it forms a transition zone to ecosystems of mixed (oak-lime-hornbeam) forest plants.These plants unquestionably grow into a natural protective system of surface waters against contamination flowing down from areas used for agricultural purposes.Buffer zones provide the opportunity for self-cleaning, and according researchers they are among the most efficient natural tools to protect a catchment area.They can reduce the amount of sediments and nutrients carried by surface water flowing down from agricultural areas.Besides positive effects, the zones are accompanied by the phenomenon of flow blockage, which is particularly hazardous in case of directing great water away from its main channel.Shrubby vegetation retains small elements of plant origin and thus the free flow of water stopped.The article analyses the effect of vegetation structure density on flow conditions for small plant debris on a laboratory scale.
