The scientifc results obtained from the research in the Tigheci hydrographic basin (located in the northwest of the Tigheci Hills) argue the immense agricultural potential of the region, but the erosion processes lead to a reduction in the amount of humus and nutrients in the soil, thus limiting the ability to productivity. erosion is the most widespread geomorphological process, has an appreciable intensity especially on the agriculture lands, where the average rate of soil loss, estimated according to the ROMseM model, is 2.16 t/ha/ year. although erosion is seen as a bio-physical process, the way of land use contributes signifcantly to the appearance of this form of degradation, having numerous economic consequences. Thus, it was found that the soil loss values are higher on arable land (about 11 thousand ha aﬀected), followed by pastures (over 2 thousand ha) and perennial plantations (about 1000 ha). The need for such a study in order to estimate soil losses is of great importance, because only by quantifying the risk can diﬀerently measures, ways to prevent and combat erosion processes be developed.
