The Mozhaysk Dam on the Moscow River has changed the sediment flow, leading to a decrease in sediment load and peak concentrations. This is mainly due to changes in river flow and less erosion from cultivated land. The dam has altered the natural sediment patterns, with a significant drop in sediment below the reservoir. However, some sediment is still released from the reservoir, helping to maintain sediment levels. By studying water turbidity, researchers can now estimate sediment load more accurately than before.
