Summary:

The aim of this study is to analyze the turbulence value in the basic hydromorphologicalunits of mountain river in the example of the Skawa river section. In four hydromorphological units - pool, run, riffle, rapid in eight random locations the instantaneous velocity components were measured usingMicroADV at 20% and 40% of the local depth. On the basis of the measurement the value of the local velocity and turbulent motion parameters: turbulence intensity and turbulent kinetic energy were calculated. The results show a large variation in local turbulence parameters within the one unit. The value of turbulence parameters increases with velocity values andordering unit as follows pool, run, rapid, riffle. It was noticed that turbulence increased towards to river bed in units of low flow velocity values -pool and run. While units with higher flow velocity (riffle and rapid) did not show similar trend.
