Opis:: The study deals with landslide threats in a low-relief region which exemplifies an area rarely perceived as prone to such geohazards. Actually, in the gently undulated landscape in the vicinity of Koronowo at the Brda River (South Pomeranian Lake District, northern Poland) intensified landsliding was observed in the recent years. The field mapping and examination of air photos showed that endangered terrains are fairly extensive and cannot be limited to initially identified slope failure incidences (hot-spots). The devised landslide susceptibility and hazard map is an outcome of predictive modelling using empirical likelihood ratio function (LR) with respect to seven evidential layers: elevation, slope angle, slope aspect, flow accumulation, surface deposits, depth to glacial raft, land cover as well as the landslide scars. The values of potential losses were calculated based on the mapped land-use categories and current market prices of estates and services. The final map, which resulted from combining landslide hazard with potential losses, shows damage propensity in a spatial scale of the town surroundings. It is meant as a supportive tool for decision-making with regard to allocating funds for stabilization measures or planning placement of new investments. On this background, stabilization solutions for selected sites are assessed in a cost-benefit context.

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.
