EVALUATION OF THE IMPACT OF LAND USE CHANGES ON THE OUTFLOW FORMATION FROM LOCAL MICROCATCHMENT OF THE WUELS ARBORETUM AREA IN PAWŁOWICE

In the paper the impact of land use changes localised in catchment of the Wrocław University of Environmental and Life Sciences (WUELS) arboretum in Pawłowice near Wrocław on outflow from local micro-catchment was analysed. The study results show necessity for solutions that allow increasing the efficiency of rainwater management discharged from the sealed surfaces in the arboretum area. In this study the selected investments that are planning to improve water condition of forest habitat and to decrease flood risk of lower localised area were characterised. The planned investments include the development of various forms of small scale retention taking into account the aspect of improving water quality.
