Summary:

In the local spatial development plan for Wiśniowa district covering the area of Węglówka village there have been formed areas with the possible existence of landslides and screes. The aim of the article is the analysis of the two out of nine distinguished landslide areas paying special attention to the legitimacy of their formation and possible dangers resulting from the settlement of these areas. Among geomorphological processes, landslides constitute the most negative process from the point of view of the economic activity of people living in the area. The range of this problem is so wide that the classical methods of field observations are no longer sufficient. Therefore, besides the traditional methods, such as geological field studies, there have been applied also more considerably modern methods in the article such as: – tachometric measurement of the lie of the land carried out with the use of Leica TCRA 1203 total station, applied for collecting field points; – interpolation made with the use of the programs such as CorelDraw, Micromap and Surfem, applied for the creation of elevation models for landslide areas; – GPS technique used in geological field studies; – vector analysis, applied for the calculation of gradients resultant vectors; – statistical analysis with the use of the Rayleigh’s test applied to check the gravity (importance) of gradients resultant vectors. The carried out studies, measurements and observations revealed that some landslide areas should be verified once again paying special attention to a threat that they pose to current and future inhabitants. There are also speculations that there is a possibility of the existence of other landslide areas that were not included in the local plan.
