Soils can be defined as four dimensional natural bodies, where the lithosphere, the atmosphere, the hydrosphere and the biosphere are soil ? forming factors which operate in geological time. The soil profile reflects the climate change passed during soil ? forming process. The majority actual soils are the result of a polyphasic soil development, therefore they involve in their age the climate existing in the Tertiary, especially in the Quaternary, period. Climate change is expected to have several effects on soil...

In the hydrological area of Banat from Romania, 20 bodies of underground water were identified and delimited, out of which 5 are cross-border underground water bodies. The present paper characterizes the underground water bodies in the B?rzava catchment area, which has an area of 1202 km2, with an average altitude of 289 m. The B?rzava catchment area occupies the central part of the Banat catchment area, bordering the north and east with the Timi? catchment area, to the south with the Nera catchment area and to th...

Evolution and development of landslides is influenced by a number of natural factors (soil, geological substrate, relief, climate, vegetation etc.) and anthropogenic factors (deforestation, overloading of land with constructions, inadequate meteoric waters drain, artificial undermining of slopes-embankments for roads etc.). In this paper we propose to analyze the causes of landslides that affected the county road DJ 585 located in Visag area, Caras-Severin county limit, and also to issuing technical solutions for ...

Hydric soils, named as Gleysols and Stagnosols, have formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part of soil profile. If microbes are active (>50C), if the soil is saturated with stagnant water, and there is a source of usable organic matter in the soil, then redox feauter will result. In the region Banat, situated in the north west of Romania, there is a large area with soils that have water excess: hydric soils, wi...

Study of soil cover is particularly important for solving the occurred problems from implementation of infrastructure works of the roads. The soil cover is at the upper part of the Earth's crust and has distinct properties morphological, mineralogical, physical and chemical differences due to climate, relief, waters. The interrelatedness of the various geomorphological, climatic, hydrological and soil factors and the human factor, resulted in a wide variety of soils with specific and constantly evolving. In Timi? ...

Soil erosion is a naturally occurring process on all land. The agents causing soil erosion are water (especially on sloping land) and wind (especially on horizontally land), each contributing a significant amount of soil loss each year. These factors are responsible for about 84% of the global extent of degraded land, making excessive erosion one of the most significant environmental problems worldwide. Soil erosion is a slow process that continues relatively unobserved, or it may occur at an alarming rate causing...
