Abstract
The main objective of the proposed project is to evaluate variability of mesohabitats at different flow regimes in regulated rivers in conection with the community of phytobenthos. According to analyses and sampling, the hydromorphologic and physico-chemical characteristic of mesohabitats, which preserve the community of water organisms, especially phytobenthos in at least good ecological staus will be defined.
The researches will take place on regulated rivers sections in Slovenia, which belong to different eco-regions: alpine, dinaric, panonic and mediterranean.The reference sites will be chosen in the rivers sections upstream from the water abstraction, more sites for analyses will be determined in the rivers sections, which are impacted by water abstractions. On rivers sections the mesohabitats will be analysed, their hydrologic, hydraulic, morphologic and phisico-chemical characteristics and sampling of phytobenthos will be carried out. The maping and analysing of mesohabitats and sampling of phytobenthos will be carried out at different flow regimes.
The impact of increasing water flow on increasing of particular mesohabitats on regulated river sections will be assessed.The corellation of parameters, which form mesohabitas and phytobenthos will be analysed with appropriate statistical methods.
The hydromorphologic characteristics of mesohabitats which affect the phytobenthos community will be defined. According to species composition and biomass of phytobenthos the requirements of water body will be defined for achiving good ecological status. The results of the project will contribute to the understanding of increasing flow in regulated rivers on ecological status.
