Abstract
This paper is an introduction to a collection of nine studies that are intended to fill the gap in the literature associated with landform development and landscape changes related to natural forces and human activities in the Central European Mountains and their close forelands. The papers are grouped into four general categories that describe the influence of climate on glacial landforms and snow avalanches, the evolution of slopes in high mountains, the development of mid-mountain relief, and changes in fluvial systems in mountains and their forelands. This paper summarises the contributions of these studies to this special issue and attempts to outline possible avenues of future research on landforms and landscapes in mountainous areas.

Abstract
The article presents the evolution of water temperature changes in the Wisłok river (the upper Vistula basin)as an effect of Besko reservoir, existing since 1978, with a capacity of 15 million m3. The thermal effect of thissmall Carpathian reservoir is compared to that of larger reservoirs located in the region. As has been found in the analysis, the direction (increase or decrease) of the annual water temperature variations in the Wisłokas a consequence of the thermal conditions in the reservoir is the same as in other Carpathian rivers downstream of larger reservoirs. On the other hand, the scale of that effect is much smaller and it is observablein a shorter section of the river compared to other rivers with reservoirs. Therefore, the thermal effects of Beskoreservoir may be considered of little significance for the natural environment.
