    ESTIMAREA CANTITATIVĂ A PIERDERILOR MEDII ANUALE DE SOL PE DIFERITE CATEGORII DE UTILIZARE A TERENURILOR. STUDIU DE CAZ: BAZINUL HIDROGRAFIC TIGHECI
    (CEP USM, 2024) Bunduc, Tatiana; Bejan, Iurii; Sochircă, Vitalii; Bunduc, Petru
    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.

    ASPECTE GENERALE ALE REGIMULUI HIDROLOGIC ALE APELOR DE SUPRAFAȚĂ ÎN PARCUL NAȚIONAL ORHEI
    (CEP USM, 2024) Angheluța, Viorica; Bejan, Iurie; Bunduc, Tatiana; Jechiu, Iradion; Boaghe, Dionisie
    This study is oriented towards the analysis, evaluation and appreciation of the hydrological regime of the surface waters in the Orhei national Park. The hydrographic network of Orhei national Park is well developed, comprising 124 rivers and streams with a total length of 257.5 km. The two main hydrographic basins include the Moța, right tributary of the Răut and Teleșeuca, left tributary of the Ichel river, along with the upper and middle course of the Vatici river, right tributary of the Răut. Most of the rivers in the area have lengths between 1 and 10 km and only 6 have lengths greater than 10 km. The assessment of water resources is based on the data from the Jeloboc hydrological station, in operation since 1958, part of the monitoring network of the state Hydrometeorological service. The average annual flow of the Răut River in this sector is 10.44 m3/s in the period 1958-2010, with a slight decrease in the flow. There are 26 water reservoirs in the Orhei national Park, most of which are small, man-made ponds, built for various purposes, such as river flow regulation, flood protection, fsh farming and others.
