The upper basin of Bârlad is clearly different in comparison to the middle and lower sectors, in what regards the genesis, evolution and specificity of the geomorphological processes. Upstream of Negreşti, the river presents a subsequent character (oriented west-east), which explains the asymmetry of the landscape, with an impressing cuesta front developed on the right side of the river. The strong regressive evolution of the tributaries from the left side (Bozieni, Poienari) and of their tributary caused a strong fragmentation of the landscape, doubled by the highlighting of the 2nd order asymmetry, as an effect of the inclination of the sedimentation deposits on the direction north-north-west - south-south-east. This paper analyses the main morphometric features, strongly conditioned by the lithology and the low base level of the river (140 m on Băceşti), directly linked or interconnected with the major geomorphological processes for this territory. The analysed area includes the sector upstream of Băceşti from the superior course of Bârlad, hydrographical basin with a perimeter of 76.2km and a surface of 215.59 km².
