Sediment Balance in the Danube River Mouth

The sediment balance in the mouth of the Kiliya Branch was analyzed on the basis of new data on the Danube sediment runoff and its distribution among branches. Through the comparison of variations in the fan volume in the branch mouth with the sediment runoff of this branch it was found that the sediment runoff data were underestimated, because they did not take into account the tractional load. The introduction of an appropriate correction made it possible not only to assess the sediment balance components for the Kiliya Branch mouth, but also to specify average long-term values of sediment runoff of the Danube River proper.
