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; ...
Landslides are one of the most common events that cause natural disasters. Therefore, performing geodetic monitoring of moving soil mass is necessary to ensure the safety of people and their property. During geodetic surveys connected with landslides monitoring it is very important to plan the moments of observations in a correct time periods. Choosing appropriate moments of observation series can give the observer proper view on progress of process kinematics with identification of development stages of process, which occur sequentially with various severity and frequency. Authors presented the rules of planning observation series during geodetic surveys of deformations according to literature. They focused mainly on formulas connected with ground deformations caused by underground exploitation and gave proposition of planning observations series on the example of landslide, taking into account factors influencing the intensification of soil mass movement, such as water saturation of soil, geological structure of the area or soil type and its properties. ...
The article presents the concept of a measurement unit for monitoring landslide risk areas. The unit is a part of an innovative integrated system created for long-term measurements. The apparatus allows to measure the changes in baseline lengths between the points mounted on the ground. Configuring the system and measurement equipment will allow automatic measurement and remote data transmission. This paper presents the components of the measuring system and the sample implementation of the system in the area adjacent to the landslide in the Milówka village (hamlet Prusów). The first results of measurements are also pre-sented. It is worth mentioning that both single item and the proposed system may support the decision-making procedures in order to determine the suitability of land for investment purposes. ...
The paper presents landslides threats occurring in the community of Zakliczyn (the Małopolska region) in the context of spatial planning. Moreover, it enumerates an available sources of landslides information used for planning purposes. Particular attention was paid to the implementation of achievements and existing effects of SOPO project - The Landslides Cover Systems. SOPO is a proj-ect thanks to which our country return to the concept of general geotechnical studies.It was found that one of the most serious problems of the local planning in Zakliczyn is a big participation of landslides areas in the general area of the mu-nicipality. This causes problem with finding the investment areas, including buildings areas. As one of the most effective ways to prevent and minimize landslides damage was considered actually carried out planning and zoning. ...
The paper presents results of shallow landslides research located in Siary near Gorlice in June of 2010. In the frame of investigations were done in-situ tests including evaluation of geologic- engineering condition near the landslides and laboratory tests including determination of geotechnical properties of soils (grain-size distribution, Atterbergs' limits, shear strength parameters). The main part of paper included analysis of infiltration process and its influence on stability of slope. There were used two methods describing water flow through unsaturated soil: piston model of Lumb and Montrasio-Valentino model. Tests and slope stability analysis results proved that main factor controlling failure of analyzed parts of slope were very intense rainfall, which caused saturation of superficial slope layer built of gravelly silt. The another factor which contributed to saturation were impermeable soil layer of cohesive soil. Integrated infiltration and slope stability calculation results using Montrasio-Valentino model revealed its sensitivity on K parameter, which describes drainage capability of soil. It was indicated that K parameter can be interpreted as function of coefficient of permeability. Slope stability calculations made using Montrasio-Valentino model in analyzed case gave less values of stability factors than the ones based of infiltration calculations using piston flow model.

Mass wasting processes are very dangerous phenomena, mainly due to their unpredictability. Moreover, their tumultuous and rapid character has led to attempts of predicting the places of occurrence of such phenomena and to assess the possible threat. Unfortunately, it is not possible to monitor all potentially unstable areas, however, temporary monitoring of such areas, that are already activated, is legally required. Monitoring the area prone to mass movements is essential to assure the safety of its inhabitants and their possessions. The article presents the example of a surveying solution which was applied to monitor the landslide areas as well as their surroundings.The subject of the research was the landslide that occurred within the area of the Carpatians flysch in the village of Kłodne. Its activation, disastrous in its effects, occurred in 2010 and was caused by an intense rainfall. The first described stage of the research was the design and stabilisation of a control network. This resulted in the stabilisation of 68 points creating an observational network. The next stage, described in the article, was conducting two observational series using both satellite and classic measurement techniques. In the following part of the article, the results of the field measurements were ...
