Spatial and temporal dynamics of linear erosion in the Republic of Moldova

Abstract

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.
