ABSTRACT
The aim of the study is to determine what influence made various forms of land use of catchment area on the size and variability of the outflow. Linking the flow rate with the forms of land use will determine which factors affect the runoff in the basin. The object of the research is Strzyża river basin situated within the administrative boundaries of the city of Gdańsk. It was found that streams flowing through urban areas, including the city of Gdańsk (river Strzyża), quickly react to any excess water. Heavy rain combined with the discharge of water through the storm sewer system results of increasing the flow and runoff in streams, among others, Strzyża river.
