ABSTRACT
The environment of the contemporary, fast-growing, cities is exposed to numerous risks related to progressive urban development, extension of engineering infrastructure and transportation, growth of services and industry as a result of which the greater and greater anthropogenic impact upon the environment takes place. A frequent phenomenon accompanying the spontaneously implemented changes is degradation of cities’ spatial structure that leads to irreversible changes in their functioning. The research on cities’ natural threats, including potential water erosion have been conducted for many years. In case of superficial extension of built-up areas in the cities, including their outskirts, more and more often they happen to invade onto the areas being at risk of water erosion. Water erosion of soil is a natural process and its intensity is determined, among other things, by some anthropogenic factors such as the uncontrolled urban development, inappropriate implementation of infrastructure. The City of Kielce, due to its location within the Świętokrzyskie Mountains and its dynamic growth, is exposed to water erosion risk to a large extent. Having used the data gathered in the Spatial Information System for the City of Kielce, a soil and gradient map within the City was elaborated and further compared to a area coverage map as a result of which a potential water erosion risk map was generated. The analysis was performed with the use of the ArcGis software. The final part of this paper deals with the analysis of City’s urban development documents in respect of the arrangements related to erosion risks and methods of its prevention, land development trends for areas at risk by efficient development of urbanized land as well as protection of open ground

Keywords: Kielce, water erosion, hazard of soils with erosion, land development
