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.

Bóbr River Valley
Western Sudetes
Opis:
The paper presents results of field mapping and geomorphometric LiDAR DEM-based analysis of the Bóbr river valley (Izerskie Foothills, Western Sudetes), between Wleń and Nielestno, where a number of individual landslides and their groups were recognized in 2015-2016. The area affected by mass-movements is located within the Wleń Graben - a regional geological unit that constitutes the south-eastern prolongation of the North-Sudetic Synclinorium. The Wleń Graben is a NW-SE trending, elongated morphological and structural depression composed of sedimentary and volcanic rocks of Late Carboniferous, Permian, Triassic and Cretaceous age. The specific geological structure of the graben is reflected in geomorphic features of the study area. Based on mass movement classifications, the forms are considered as: (i) deep-seated rotational landslides (Świerkowa Dolina and Czerwony Wąwóz landslides); (ii) shallow slides and flows of weathered material and rock blocks (headwater areas in the south-western slopes of Gniazdo Hill, "Izerskie Gołoborza” locality), and (iii) complex landslide forms (deep-seated and shallow landslides on the south-eastern slopes of Gniazdo Hill). The studies confirmed the usefulness of geomorphometric analysis based on LiDAR-derived DEMs combined with field investigations. The landslides are located mainly in heavily forested mountainous areas. It was probably the main reason they had not been identified in the past.

Opis:
The paper presents the results of field mapping and structural analyses conducted within the landslides situated near Ludwikowice K³odzkie, in the central part of the Nowa Ruda Basin (Middle Sudetes, SW Poland). The area affected by mass movements is located within the eastern limb of the Intra-Sudetic Synclinorium (Głuszyca Monocline) composed of Upper Carboniferous to Lower Permian (Rotliegend) sedimentary rocks. Nine individual landslide forms, ranging in area from 0.5 to 22.7 ha, including two landslide complexes (Sokółka landslides, 49.7 ha in total area) have been identified and described in terms of their origin and geological conditions. Studies of landslide morphology and structural analysis allow recognition of several types of mass movements. They include: (i) rotational landslides (landslides Sokółka 1-3 and 5); (ii) translational slides (landslides Miłków 1-3); (iii) deep-seated, compound landslides (landslide Sokółka 4), and (iv) topple evolving into deep-seated rotational (?) slide (Sławosz landslide). The studies repeatedly confirm the usefulness of analyses of LiDAR digital elevation models coupled with field investigations and structural analyses.
