Opis:
The paper presents the principles of the inclinometric method in the measurements of underground displacements of slopes are described and some example results. The advantages of the method and the practical examples are shown: results of the measurements on the slopes in the flysch Carpathians and Polish Lowland - i.e. in the Beskid Niski Mts., Beskid Ma³y Mts. and in Koronowo near Bydgoszcz. The capabilities of the method are described in detail. These include determination of the depth of the landslide slip surface or zone, description of the slide mechanism (rotational or translational), estimation of displacement rate and its connection with the external conditions, and determination of the movement direction.

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.

Opis:
In the recentyears intensified landslidingwas observed in the surroundings and in the town of Koronowo near Bydgoszcz. (Krajeñskie Lake District). The gently undulated moraine upland, a wide valley of the Brda river, its relatively steep valleysides and incised valleys of tributaries are morphologicfeatures related to modeling by North Polish Glaciation. Quaternary tills alternated with fluvioglacial sands and gravels are underalined by Miocene clay and mud with brown coal intercalations. Due to such morphologic and geologic setting the study area isprone to slope instability. Failure apt soil massifs were assigned to 4 groups. Out of 32 identified landslides, 9 were selected for detailed examination. To register a nature and rate of failures a complex monitoring system was installed on slopes where the selected landslides resulted in severe damages to municipal infrastructure. The system was facilitated with inclinometers andpiezometers, supported by a network of GPS-RTK geodetic benchmarks as well as with a recording weather station. The performed examination revealed that the most unfavourable arrangement of the layers is, when under a non-cohesive soil (e.g. sand, gravel) lies a cohesive impermeable layer (e.g. clay, loam). The landslides are rather shallow ones (except 2 incidents) with slow rate of displacement of an order offew mm/year. The landslide triggeringfactor is water originatingfrom precipitation and snow melting. Influence of water was especially significant in early Spring 2011, due to the combined effect ofsnow melting and infiltration of thawing water originating from the former, exceptionally high rainfalls. The influence of hydrologic conditions on slope deformations is complex. There is a significant timelag between a movement initiation and unfavourable hydrometeorological conditions. That is exemplified with the landslide that was initiated in February-March 2011 in consequence of atmospheric conditions of November-December 2010. The obtained results formed the background for inventing engineering treatment measures aiming at current remedial stabilization of slopes and mitigation ofpossible landsliding in the future.
