    Opis:
    Celem artykułu było przedstawienie zasadniczych problemów kartograficznych przy rozpoznawaniu i dokumentowaniu osuwisk oraz terenów potencjalnie zagrożonych ruchami masowymi w obszarach miejskich Gdańska i Gdyni. Określenie lokalizacji i stopnia aktywności osuwisk oraz zagrożeń związanych z ich ponownym uruchomieniem wspomoże władze lokalne we właściwym zagospodarowaniu przestrzeni oraz wypełnieniu obowiązków dotyczących problematyki ruchów masowych wynikających z odpowiednich ustaw i rozporządzeń. Rozpoznanie lokalizacji i zasięgu osuwisk jest pomocne w tworzeniu planów odnoszących się do ryzyka osuwiskowego, czyli w ograniczeniu w znacznym stopniu szkód i zniszczeń wywołanych rozwojem osuwisk oraz zaniechaniu łub dostosowaniu budownictwa drogowego i mieszkaniowego w warunkach panujących w obrębie osuwisk.
    The aim of this article is to depict the fundamental cartographic difficulties towards appropriate recognition and evidence of landslides and areas potentially at risk of mass wasting, within urban zones of Gdańsk and Gdynia. Designation of landslide location, activity, and assessing a threat of landslide reactivation, is going to support the local authorities spatial planning accuracy - an obligation resulting from the adequate laws and regulations. A proper recognition of landslide location and coverage helps to apply suitable arrangements, aiming to reduce the damage caused by landslide development, as well as omission, or adaptation of road construction and housing, within areas being at risk of mass wasting and landslide activity.

    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.

    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.

    Late Glacial
    Opis:
    The area of Poland, including the Carpathian Mountains, is located in a zone where landslides cause large material damage. This issue can be considered using different time scales. Using various dating methods, it was possible to distinguish periods of increased landslide activity. Among others, the radiometric methods are the most common. Based on the 14C dated landslides in Szczawnica-Biafy Stream, Zapadle near Szymbark, Rychwatd near Żywiec and on data published by Margielewski (2006), it was possible to hypothesize that landslides in the Carpathians have been developing over 13,000 years, i.e. since the Oldest Dryas. This is related to the beginning of degradation of the permafrost, which can be considered as the inception of the development of large rock landslides. On the basis of the presented data, it can also be stated that these landslides have been active up to modern times and their development is very long. An example of this is the landslide in Zapadle. The position of the landslide tongue, which is subjected to erosion, is of great importance, which promotes its further activity. Permanent removing of the colluvial material by a stream and its supplementing by subsequent new displacements from the scarp causes that the landslides can be active for a very long period of time.

    Opis:
    Mass movements are an ever present threat to building construction, water management, vegetation formation and biodiversity. This paper presents an approach to landslides research based on non-invasive geoelectrical method - Electrical Resistivity Tomography (ERT). Mapping and displacement monitoring of unstable slopes is crucial for the hazards prevention and assessment. The ERT technique is an effective tool to obtain structural differentiation of geological medium through interpretation of 2D electrical resistivity models. The main advantage of the method is a wide range of applicability what makes its useful during field works on a landslide. It is commonly used for measurements of slope instability, determination of shear surface, landslide susceptibility, depth of bedrock, slip plane geometry. The aim of the work is to identify the geological structures underneath three selected landslides in south Poland: in Racibórz, Milówka and Porąbka. Attempts have been focused on determination of the usefulness of the proposed ERT methodology for evaluation of possible further development of mass movements. On two investigation sites two different arrays have been used: Wenner-Schlumberger and dipole-dipole which allowed to prepare combined data set and resistivity models based on them. Forward modelling of synthetic models based on a priori information allowed to understand anomalies present on resistivity models. Applied approach ensured quality increase of final interpretation of resistivity models.

    Opis:
    When conducting geological and engineering research, the most common statement is information that the landslide is shallow and should not pose a threat to the designed objects. In the case of large, structural landslides, this approach may lead, with the wrong determination of the deepest slip surface, to the occurrence of a construction disaster as a result of improper execution of the protection structure. The article presents specific locations of landslides with deep displacements in inclinometric columns exemplified by landslides monitored as part of the SOPO project in Tarnawa Górna, Słotowa and Międzybrodzie Bialskie - Łazki. The documented slip surfaces are found at depths of 19-42 m. Such deep displacements indicate that large, landslides reach significant thicknesses and such data should be presented in a geological and engineering documentation. It is proposed to modify the regulation on the execution of the geological and engineering documentation by adding a point regarding the documentation of landslides. If such an area exists, special requirements must be met when conducting geological surveys.

    In 2010-2015, various research teams conducted geological operations on the Kurów landslide. They independently documented the course of deep-seated slip surfaces. The studies were carried out in three stages, embracing preparation of expert’s reports, geological documentation, and reports on monitoring work. The procedures used in Małopolska, worked out within the framework of the SOPO (LCS-Landslide Counteracting System) project, were of great importance during the recognition and protection ofpart of the landslide area. It was proposed that the scope (depth and distribution of boreholes) have been consulted with the appropriate representative of the scientific surveillance of the PGI-NRI Carpathian Branch in Cracow before the tendering procedure.

    Opis:
    In this contribution the author presents the results of geological and geomorphological field mapping and structural analyses conducted within the area of a newly recognized landslide situated near Włodowice, in the southern part of the Nowa Ruda Basin (Central Sudetes, SW Poland). The landform is located within the eastern limb of the Intra-Sudetic Synclinorium (Nowa Ruda Monocline) built of Upper Carboniferous to Lower Permian (Rotliegend) sedimentary rocks. Geomorphological characteristics of the landslide are presented, but the greatest attention is paid to the way of transformation of individual structural elements of basement rocks (bedding surfaces, sets of fractures) by mass movements. The study allows recognition and interpretation of landslide type according to failure mechanism - the analysed form represents a typical translational landslide with a flat, structural slip surface related to bedding planes. A model of the development of a translational landslide under specific geological conditions (monoclinal structure built of different lithological varieties of sedimentary rocks with different rheological properties) is presented. Due to the partial exposure of the slip surface in the upper and lower parts of the landslide, the form should be considered unique among the previously identified landslides in the Sudetes Mts. During this study the author repeatedly confirms the usefulness of analyses of LiDAR models in landslide investigations.
