This article offers the results of an analysis of natural and anthropogenic impacts on eolian coastal marine natural complexes of the Curonian and Vistula spits. The authors identify the contribution of natural and anthropogenic factors to the transformation of the spits’ natural complexes.
This article considers the influence of terrain on the assessment of natural system sensitivity to anthropogenic impact. The author presents a classification model of natural system sensitivity to anthropogenic chemical and mechanical impacts. The article examines certain cases of the influence of terrain on the assessment of natural complex sensitivity in the areas of oil exploration drilling located in different geomorphic regions of the Kaliningrad region.
This article presents a study into the shape variation of thermokarst lakes coastal boundaries carried out on six test sites in Eshtykol in the Altai Mountains. The authors describe the methodological issues of the statistical analysis of lake boundary variability with the help of satellite images. The authors show that the degree of lake shoreline variability is increasing with time. The study results can be used in modeling the fields of thermokarst lakes and research on thermokarst dynamics on permafrost territories in the conditions of climatic changes.
This article focuses on the development features and distribution patterns of karst rocks in the Perm region, as well as their impact on the economic activity.
This article considers the hydrogeological parameters of the karstosphere and emphasises its unstable regime in the transit areas. Deep karst water zones and their catchment areas are more stable, in discharge areas they are characterised as weakly thermal. The sulphate karst is the site of formation of sulphate-calcium water with mineralisation of ≥ 3.5 g/l. Sulphate-sodium and soda subtype water with mineralisation of 0.3÷0.5 g/l forms in the areas of development of younger sediments. The hydrochemical method proved to be very
efficient when studying karst.
