The ecohydrological approach can be applied to reconstructed wetlands where an appropriate vegetation design is needed in order to optimise hydraulic behaviour, water quality improvement and biodiversity increase. The purpose of this study is to examine the hydraulic effects of different development stages of vegetation in a demonstrative reconstructed wetland in Italy characterised by a central canal and two vegetated lateral shallow zones. Tracer tests were carried out in different vegetation conditions. The residence time distributions were analysed using several parameters. As expected, the results show that with more developed vegetation the hydraulic dead zones increase. On the other hand, a moderate increase of vegetation density doesn’t hinder the flow, but rather increases dispersion number. A proper design has to avoid hydraulic short circuiting and provide a good distribution of the flow especially in the vegetated zones.

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.

Riparian vegetation is a typical ecotone by its structural and functional position between the terrestial part of the watershed and the stream (Naiman, Decamps 1990). In consequence, the riparian zone forming an integrated component of stream ecosystems significantly determines the aquatic community. Macroinvertebrates are affected by defined variability of environmental factors. In streams under canopy: light access is reduced; summer temperatures are lower; shed leaves form the main source of energy; insects falling from the vegetation into the water create another source of food; roots from trees form shelter and strongly influence hydraulic patterns. As a result, many (micro) habitats can exist and persist. The relationships between the covered percentage of the riparian zone, hydraulic processes, POM retention and macroinvertebrate functional organization was analyzed. Riparian vegetation forms a buffer zone in agricultural landscape and thus prevents inflow of nutrients, but also of fine sediments. Clearing of riparian vegetation changes all these conditions, resulting in a totally different and less varied biocommunity. Examples are given from Poland and The Netherlands.
