In the paper, after presenting the terraces identification methodology (field research, drilling data, fauna remains, cartographic materials, satellite images, and bibliographic sources), describes rock type structure and morphometric parameters of terraces and rivers beds levels in the area of the biggest hydrographic basin located between the Prut and Nistru rivers – the Raut river basin. They identified and described five Pleistocene terraces and two levels of the upper Pliocene age in the river’s valleys. A detailed rivers terraces levels analysis showed that fault and folded formations found in the sedimentary cover of Moldovan plate, together with hydrologic characteristics and basic level oscillations were part of the fluvial morphogenesis during Neogene and Pleistocene age.

The high degree of land use in the Republic of Moldova as a whole, and the Cogâlnic river basin in particular, imposes the need to assess the quality of the environment and the characteristics of the anthropogenic pressure on the landscapes in temporal and spatial dynamics and to identifying an adequate of measure system for the purpose to maintain/restore the optimal structure and functioning of landscape systems. Based from the Land Cadastre on data, statistical data of population censuses, bibliographic and cartographic sources, a system, was appraised a system of indicators(of naturalness, of artificialization of landscapes, environmental changes) and quantified human pressure on the environment through agriculture and anthropogenic pressure on forest landscapes from the Cogâlnic catchment area. The values of the indices and the human pressure on the landscapes were processed using GIS techniques and elaborated cartographic models.

In erosion studies, special attention was paid to identifying the characteristics of linear erosion formations. Based on different information sources (cartographic materials, aerial photographs with different years of publication, land cadasters, bibliographic sources, field research, etc.) was assessed the spatial dynamics (ravins density and raven`s formation indices by geomorphological and territorial administrative units) and temporal dynamics of morphometric and quantitative characteristics the ravines in the space of Bessarabia from the middle of the XIX century and the Republic of Moldova in the second half of the XX century, and until 2020. The results of the possible influence of agricultural activities, including arable land on the processes of the linear erosion in the middle of the XIX century and the beginning of the XX century, were modeled using GIS techniques.
