This paper presents the dependence between particles of various sizes present in the sediments collected from the Klusov (Slovakia) water reservoir, such as sand, silt and clay and their nutrient content. The results of physical characteristics of sediments indicate that the clay/silt fraction dominated in the reservoir sediments. Chemical analysis showed that the total nitrogen content in sediments was recorded from 0.07 % in sediment collected at the inlet to the reservoir to 0.26 % in sediment taken near to the...

Soil erosion associated with non-point source pollution is viewed as a process of land degradation in many terrestrial environments. The question of nutrient loading of rivers and reservoirs, as it relates to sediment in general and farmland erosion in particular, is still a potentially important issue. This paper presents the suggestion of model for predicting the total nitrogen, phosphorus and potassium contents in reservoir bottom sediments. The model is based on the soil loss calculation using the Univer sal S...
