The paper presents the results of examination some basic granulometric and hydraulic parameters such as changes in granulometry, velocity, shear stresses, Froude number, Reynolds number and flow resistance coefficient within the region of two different gravel bars in the mountain stream. The sediment samples were taken from points situated along the bars and from the riverbed in the area where the bars have their influence on the river regime. On the top of the granulometry and hydrodynamics survey there were also the chemical properties of the sediments, including heavy metals, examined. The main conclusion of the paper is that a point bar (developed on the river band) is less stable, than an up-of the obstruction bar (an alternate bar) developed along the river bank. Also there are number of observations connected with the hydrodynamics influence on stream bars formation. The study was undertaken on the Skawica-Jałowiecki Stream in the Polish part of the Carpathian Mountains.
