THE ASSESSMENT OF GEOMORPHOLOGICAL CHARACTERISTICS AND THEIR INFLUENCE OVER LAND DEGRADATION PROCESSES WITHIN VALEA NEAGRĂ CATCHMENT AREA

Oana Petronela Ailincai, Remus Ciprian Cotunoaea

Abstract


The paper analysis geomorphological conditions in the drainage basin of Valea Neagră river, upstream Dulcești locality, and also the influence of the landforms over the development of  main degradation processes: soil erosion, linear erosion and landslides. The area lies on the western edge of the Moldavian Plateau, where the unit confines the Moldavian Subcarpathians. The characteristic landform is the hilly relief, with altitudes ranging between 219 m and 505 m. Geologically, the monoclinic structure of the deposits determined the evolution of cuesta landform that emphasizes the double asymmetrical structure. The relief inversions occured in the territory are the result of a long paleogeomorphologic evolution. In the studied section, the Valea Neagră river valley has a subsequent direction, except from the river section, upstream Hârtop village, where the valley is consequent. Results indicate that unappreciable soil erosion characterizes 73% of the entire area, while the landslides occupy 22% of the territory, being often accompanied by linear erosion forms.
