![]() ![]() The importance of watershed management in relation to the sediment management has increased, as the number of dams and their ages increase. Reservoir sedimentation is a complex process that varies with watershed sediment production, rate of transportation, and mode of deposition. The dam construction dramatically alters this balance since the increased flow depth and decreased flow velocity of a reservoir, reduces the sediment transport capacity and causes settling. Most natural watercourses are approximately balanced with respect to sediment inflow and outflow. Soil erosion by water is one of the greatest environmental challenges facing the Globe, being equally challenging problem for the countries of the Balkan Peninsula, changing the quantity and quality of their water resources, reducing at the same time availability and use of fresh water. The concerns about erosion are related to accelerated erosion, where the natural rate is significantly increased by human activity. Soil erosion is a natural process, occurring over geological time and is essential for soil formation.
