The activity of water erosion in Albania is favoured from some factors like relief, geological structure, slope, soil, etc. Erosion depth growth is closely related with the vegetal cover ravage high rate and in the first instance that of woodland flora in sloping ground. The degradation of the flora or total destruction of it is defined from many factors, but in notably from social-economical system of every country. It can be also seen some special areas in our country were the results of the human negative impacts in natural environment. The erosion phenomenon is more problematic, especially during intensive raining time.展开更多

In many areas of our country, mountainous and hilly territories suffer major erosion in both surface and depth, where the solids are deposited in the flat parts of the country, thus leading to a higher content of gravel in agricultural land and filling of the sewage networks. The phenomenon of erosion is greater in the vicinity of residential areas where damages are larger and more sensitive. One of the most vulnerable in our country in terms of soil erosion is the district of Tirana. This study had the main goal to define and categorise of erosion rates in natural environments of the forest economies of the Tirana, the rate of recovery of vegetation, slope and rainfall index, which will serve as information and guidance on the land use by farmers, communes and the state regulatory officials, depending on the ownership of these woodland surfaces.展开更多

On the basis of watersheds classification, 7 typical watersheds were chosen andobserved for 11 years. The result shows that the sediment at the small watershed mainly comes from gullies,which is 60% of the total sediment. Erosion modulus of valley (including gully head, gully bed, valley side)is 1.28~2.48 times as that of the area between channels(including hill slope and mound of the Loess Plateau).The main sediment source of slope erosion is cultivated land on slope without water and soil conservationmeasures.展开更多
