The long-term activity of a polymetallic ore mine in the region of Tarnita-Suceava, Romania, has resulted in an enormous amount of waste material, collected in tailing dumps and ponds. The impact of the waste materials on the surrounding ecosystem and human health are far to be fully estimated. The deposited waste has exerted negative impact on the environment, especially on the soils that host dumps and drainage waters. Heavy metals, including arsenic also interfere with the metabolism of plants, and reduce the n...

In the present work the researches were carried out in the Tata Valley watershed, which has an area of 17 km2 and administratively belongs to Dambovita county, Romania. The purpose of the study was to estimate the soil losses for a single storm event in the Tata Valley watershed using the MUSLE method and G.I.S. The identification of the erosion processes and the estimation of the quantity of eroded material is extremely important both for the elaboration of the risk maps, as well as for the analysis of the surfac...

In the mountain zone, the slope exposure plays important role in the process of soil formation. The aim of the work was to assess the impact of slope exposure on the soil properties of agricultural terraces in the Eastern Caucasus. A study of soil properties of agricultural terraces in the mountainous zone of the Eastern Caucasus (Dagestan, Russian Federation) was carried out. The purpose of the study was to compare the soils of agricultural terraces on the slopes of the northern and southern exposure. The content...

The research papers for the present study were carried out in the 2018-2019 period in the river basin of the Muscel stream, a tributary of the Dambovita river, in Romania, using the empirical method of weighted overlay of thematic maps and GIS, resulting the hazard maps considering landslides which occurred on the scale of the studied drainage area. For the application of the research method, the necessary data regarding the digital terrain model, the land cover with vegetation and the degree of urbanization, were...
