Bečva R. is an originally anabranching gravel-bed stream
drains the Czech part of the Flysh Carpathian Mts. as a left tributary of
the Morava R. The Bečva R. begins by confluence of two source streams, the northern Rožnovská Bečva R. and the southern Vsetínská Bečva R. The drainage area is 1620 km2. The mean annual discharge of the river reaches up to
17.3 m3 s-1 at the Dluhonice gauging station, where the
basin area is 1592
km2 (data source: Czech Hydrometeorological Institute).

We started with monitoring of the Bečva R. channel. First
part of research is connected with use of geodetic survey, grain-size analysis
and modeling of sediment transport. Main aim of our research is focused on
evaluation of transport parameters of selected channel reaches. The set includes single-thread, channelized and incision affected reaches, compared with
anabranching renaturated reaches (they were renaturated by flood event in year 1997).
Other aim of this research is a sedimentary budget of the channel segment from
the point of view of transport parameters.
