The article discusses how sedimentation in lakes and reservoirs can show changes in climate, land use, and dynamic conditions. Researchers studied various lakes and reservoirs to understand how urbanization, radioactive elements like Caesium-117, and natural processes affect sedimentation rates. They used techniques like seismic surveys, electron microanalysis, and particle tracing experiments to analyze lake sediment stratigraphy and geomorphology. Key findings include the impact of Chernobyl-derived radiocaesium on reservoir sediment, sediment budgets in different regions, and late Pleistocene sedimentation patterns near the Dead Sea.
