Opis:
On the basis of research and performed numerical stability analysis of two landslides, authors present issue of mass movement activated as a result of dump soils formation.The problem disscussed concern of dump soils used to build uncontrollable embankments, compensating ground surface or activate mass movement on relatively stabilized landslides according to improper liquidation by application dump soils. Significant reasons for landslides development in such conditions are instability of the soil structure, dump soil properties variability and a high sensitivity to external influences, in particular changes in moisture.

Opis:
The paper describes the geomorphological and geological structure of the cliff Baltic bank in Jastrzębia Góra. The detailed description and analysis of the landslide developed in the selected cross-section of the cliff is provided. Extensive complex investigations involving multiple techniques are described. These methods include the borehole drilling and inspection of the soils composing the slope, laboratory tests of the shear strength parameters by the triaxial compression method, slope stability calculations basing on the finite difference method and inclinometric measurements of the displacements in the borehole performed on the slope. The results prove that the extent of the landslide is limited to the upper part of the slope. The stability factor lower than 1.0 and the continuous displacements measured in the borehole indicate the recent cliff instability. Therefore the works for slope stabilization are strongly recommended.

Opis:
When conducting geological surveys in landslide areas, it is important to define the scope of the planned geological works. The most important issue in the study of landslides is the recognition of the depth and shape of the slip surface. This requires the correct type of drilling and a good core quality. Most often, within a single landslide, several slip surfaces are documented, which occur at different depths, which is associated with a complex manner of motion and shear. Proper determination of the deepest sliding surfaces allows for the construction of a calculation model and selection of the optimal method of securing the landslide area. The course of the slip surface is often not determined by the depth of the bedrock under the cover formations. Geological diagnosis should depend on the size of the examined landslide and the impact of its activation on potential damage / destruction of existing buildings and technical infrastructure. The method of documenting and carrying out calculations is presented as recommended in landslide areas. In the first step, calculations should be made on the basis of data obtained from field work and parameters obtained from laboratory tests. Monitoring should complement field research and assess the scale of displacements. Conducting stability calculations should be a standard for the preparation of geological and engineering documentation of landslides and areas at risk of mass movements. It allows you to assess the risk and threats to the planned investment or protective structure. This is to provide permanent safeguards to prevent damage to buildings that have been designed on the basis of uncertain geological data. It is postulated to modify the ordinance on the implementation of geological and engineering documentation by adding a point concerning the documentation of landslides. If there is such an area, special requirements must be met when conducting geological surveys.

Vajont landslide, which affected the northern slope of Monte Toc in the Dolomites (NW Italy), is one of the most famous examples of a natural disaster induced by human activity. A wave, generated by displaced material that filled the Vajont reservoir, overtopped the dam and destroyed a few villages in the nearby Piave valley, resulting in death of approximately 2000people. In this review paper, some facts about the disaster are presented and its triggering factors are discussed. Information related to tourism development in the area is also provided.

Opis:
The landslide on the northern slopes of Magura Witowska is an example ofa consequent-structural type oflandslide. It has been developed due to several favorable conditions like: monoclinal layer deposition where the dip angle and direction of collapsing layers are close to those of slope exposition. Moreover, shale packages are commonly present in the bedrock. In the lower part of the landslide an elongated basin filled with peat sediments is situated. The 8-m long profile was recovered with an Instorf sampler for 14C dating and pollen analysis purposes. The results of radiocarbon dating and pollen analysis point to Subboreal and Subatlantic age of these sediments. Undisturbed biogenic sedimentation, lack of minerogenic intercalations together with the unbroken course of pollen succession suggest that the studied landslide has not undergone any significant active events since its formation.

Opis:
In the area of landslides in Ochojno and on Stroma street in Stary S¹cz, geological works were carried out, including determination of geological-engineering parameters, and documentation of slip surface on the basis of the drill core analysis. The obtained results allowed the author to construct computational cross-sections on the basis of which slope stability index factors for each of the landslide areas were calculated. These results were compared with the values of stability index obtained from inclinometer measurements. A proposal for documenting landslide areas was presented, paying particular attention to the proper interpretation of the ground profile. This enables avoiding frequent errors made in preparation of geological-engineering documentation based on shallow ground recognition and improperly conducted drilling system.

Opis:
Landslide recognition is an important task for designers and contractors during the road construction process. The problems that contractors often face is insufficient recognition of the geological structure (at the design stage), too small area of purchased land under the "ZRiD’'decision, or the inability of fast responding to emerging threats. The studies described in this article shed more light on the complexity of slope deformation as a result of landslide processes. During the constructing of the expressway S-7, the problems related to deep landslide processes occurred, which most probably were associated with poorly recognized old “rocky-weathering material” type of landslide. The geological survey performed during the construction of this road, confirmed the occurrence of deep (>20 m) displacements, recorded by the inclinometer measurements. These deep displacements are linked to a large landslide with a main scarp located in the region of Mt. Cymbalowa Góra.

Opis:
Landslides are very common features in the Polish Outer Carpathians. In the classical cartography, landslides are recognized based on characteristic land relief: main and side scarps, toe, minor scarps, transverse ridges, recesses and cracks. Formerly, landslide mapping was carried out in the field, preceded by interpretation of topographic maps and aerial photographs. Nowadays, we use spatial data from airborne laser scanning (ALS). Spatial data reprocessing permits to achieve a high-resolution (pixel 1*1 m or more precise) digital terrain model (DTM). Exploration of land relief in search for landslides has become simpler and more accurate. DTM interpretation allows delimiting the boundaries of landslides and elements of their relief. By analysing groups oflandforms it is possible to determine the type of colluvium movement. In the eastern part of the Low Beskid Mts., four types of landslides predominate: rotational slides, translational slides, flows, and complex movements. Types of landslides are usually very well visible on the DTM. Information about types of mass movements can be useful during modelling further landslide activity and designing instrumental identification works and possibility ofstabilization.

Opis:
The basic assumptions determining the methodology for testing soil strength parameters have been known for almost 250years (Coulomb, 1773). Nevertheless, obtaining reliable and unambiguous parameter values for calculations is still a difficult problem. The main problem results from the fact that soil strength parameters are not a material constant. This means that the values of the angle of internal friction and soil coherence are dependent on the research methodology used. The article presents the impact of the method of determination of soil strength parameters on the assessment of slope stability. The earlier literature recommends adapting the method of testing samples as much as possible to real conditions. This allows the geologist to have some freedom in choosing the research methodology. The PN-EN1997-2: 2008 standard puts more emphasis on a uniform test methodology. In the interpretation of Eurocode 7, due to the need to determine accurately effective stresses, "only strength tests of soils completely saturated with water or dry soils are considered". Stability analyses performed for a small, still active landslide in Kojszówka have shown that the use of only effective parameters for slope analyses may not be fully reliable.

The main objective of the presented analysis was to investigate to what extent even minor changes in the hydrological and hydrogeological environment affect the changes in the dynamics of landslide surface displacement. The research was carried out for selected monitored landslides, which, in addition to the in-depth monitoring devices, were equipped with corner reflectors suitable for satellite radar interferometry measurements. The high temporal resolution of the interferometric data allowed demonstrating the existence of a relationship between the speed of surface movements and slight changes in the depth to the groundwater table. The analyses were performed for five landslides, which also showed a high dependence of these compounds on the geological structure of the landslide and its substrate.

Opis:
Principles of the rock massif modelling of the slopes as a discontinuous medium and examples of the numerical simulations of the deformation processes in such a medium are presented in the paper. The massif is modelled as a set of blocks, contacting themselves along the joints, so called "interfaces". Four examples of the deformation processes on the slopes using distinct element model and numerical code UDEC are described. The first example concerns the group of the rock blocks in Sudety Mts. The second presents the principles and the results of the slope deformation analysis in Carnian Alps in Italy, whereas in the third one the analysis of the landslide deformations of the rock wall in diabase quarry is presented. Fourth example concerns the analysis of the soil embankment. The possibilities, advantages and disadvantages of the discontinuous approach in jointed rock and soil media modelling are discussed. Popularisation of the discontinuous approach is suggested.

The article presents results of two-year study that included mapping of Czarna Góra (Podhale region, Carpathians), especially in local watercourses and dirt roads after the downpour of July 31, 2010. The field research shows that sudden morphological processes were induced as a result of intense rain (debris flow, which was triggered in a road cut and many shallow and small landslides in local stream valleys). The study presents results of mapping new landforms after the downpour. Because no earlier landforms of similar origin have been found in this area, it can be concluded that the event had a unique character.
