<strong>Technical</strong> <strong>Reports</strong> – Part C: Water Quality 41 4.9. Suspended Solids Discharges The rivers Prut and Siret drain the southeastern part of Ukrainian Carpaty. The average annual discharge of suspended solids in the river Prut basin amounts up to 49-241 ton per km 2 per year, 30-39 ton per km 2 per year in Cheremosh River basin, 119 ton per km 2 per year in the Siret River basin. The high rate of human induced denudation, calculated by suspended solid discharges, occurs in the stream river basins with high human pressure (for example, Siret River basin). The rivers Tisza, Latorytsia and Uzh have high-suspended solids discharges in many cases exceeding 100 ton per km 2 per year. Only in upper reaches of Tisza, Tereblia and Borjava it varies between 71-105 ton per m 2 per year. In the other river basins the suspended solids discharges vary between 11-384 ton per km 2 per year. The sediments of the majority of the rivers consist of the 5-10% particles with 0,5-1,0 mm in diameter. The highest turbidity is reported for mountainous parts (up to 500-750 g per m 3 ). The movement of bottom sediments is not sufficiently studied for the rivers of Western Ukraine. It is reported that transport of bottom sediments consists of 10 -15 % of suspended solids. In mountainous and semi-mountainous rivers this ratio may reach 70-90% and exceeds suspended solids transport by 2-3 times. 4.10. Content of the Suspended Solids Content of the suspended solids in the Danube water (Vilkovo) is presented in the Fig. 4.8. Maximal content of suspended solids is observed during the summer seasons, and because the rivers are not covered with ice during winter periods. Small peaks in springtime are related to the spring flood events.
