ABSTRACT
The paper presents the possibility of application of the hydrological model HEC-HMS in the development of a strategic environmental assessment of local spatial development plans on surface water. The practical possibility of using simulation models of catchment response to high intensity precipitation is shown on the example of the Różany Potok watercourse catchment which is subject to rapid urbanization process. The area of Różany Potok catchment is 8.1 km2 and a stream length is 5.57 km. In the years 1992–2012 there was a significant increase in impervious areas in the catchment of about 5.2 to 16%. In addition, new local spatial development plans are prepared within the catchment area. The implementation of their records may contribute to the increase in the proportion of impervious areas to over 20%. The increase in the share of impervious areas in the catchment area and traditional approach of precipitation water management can lead to doubling flood flows and increase the risk of local flooding.
