Paper Summary

Human activities have significantly changed the sediment distribution in the Pearl River Estuary in China from 1975 to 2017. The sediments have become coarser over time due to reduced upstream sediment flow, dredging, and sand mining. Sandy sediments have shifted locations, and the sediments now have a patchy distribution. These changes are likely to continue in the future with ongoing human activities.
