EROSION PHENOMENA IN THE BISTRA HYDROGRAPHIC BASIN PUBLISHEDNicoleta Nemeş, Ioana Alina Costescu
The exact appreciation of the soils degradation state, by the erosion and associated processes, is an operation that involves high costs and a long time for observations, determinations and measurements. It also requires a geographic informational system that allows to identify the spatial dates and to compare these dates and the interpretation of theses are made through analytical methods. In Romania, the intensity of the soil erosion on the agricultural lands is very high; annual 106 mil to/year of soil are lost. In Bistra Hydrographic area the surface erosion is caused by the improper usages of the lands and by the excessive grazing.
