Summary: | This work presents the impact of land cover on water relations in the catchment of the Bogdanka watercourse which is 51.9 km<sup>2</sup>. The research and analysis of available cartographic materials have shown a significant increase in the anthropogenically transformed areas due to urbanization from almost 8% in 1940 to over 42% in 2012. Urbanized areas (buildings and communication routes) have contributed to sealing the area and thus reduced retention capacity by 0.25 million m<sup>3</sup>. Therefore, the effective rainfall P<sub>10%</sub> and P<sub>1%</sub> have increased respectively by 0.4 mm and 0.8 mm. As a result the maximum flow of exceedance probability of 10% and 1% have reached over 20% in the Bogdanka watercourse. |
