City of Gdańsk is located in a coastal region where changing climatic conditions increase the frequency of extreme weather events. Developing urbanization affects the hydrology of natural basins by simplification of the drainage system and reduction of infiltration and base flow. Consequently greater runoff rates flow into storm water collection systems, reservoirs and surrounding water bodies. Not only infrastructures of urban areas but also citizens are exposed to the effects of heavier rainfalls or sudden snowmelts, resulting in flash floods, damages of hydro-technical systems, as well as environmental risks. Development of integrated solutions including precipitation, stream flow and reservoirs storage monitoring and management can reduce flood risk and help to protect the public health. In years 2011-2013 Department of Hydraulic Engineering (Faculty of Civil and Environmental Engineering of Gdańsk University of Technology) in collaboration with The Provincial Fund For Environmental Protection and Water Management in Gdańsk and Gdańskie Melioracje Sp. z o.o undertook the implementation of storm water monitoring system in the Strzyża River basin in Gdańsk. The results of measurements allowed performing the HEC-HMS hydrological model for one of the most flood prone areas of Gdańsk. Research on the development of the technical and non-technical methods of flood control, numerical modeling for build-up area inundation prediction, expansion of the existing rainfall-runoff and storage monitoring system, integrated water quantity and quality analysis are continued in frame of ongoing research project (2015-2017). The aims, objectives and preliminary results of the project will be discussed in the proposed paper on WMHE 2015 International Symposium in Brno.
