How Do You Landsat from a Delta in China

With rapidly rising sea levels and drastically declining river discharge, the Changjiang Delta, near Shanghai, China, is continually evolving. Using Landsat imagery, researchers focused on tidal level fluctuations to help understand the changes to the largest uninhabited island in the estuary, Jiuduansha island.



Researchers used 497 Landsat images from 1974 to 2020 to analyze shoreline positions and tidal exposure. The studies showed a rapid area growth rate despite a decrease in sediment deposition rates. Sustained growth is attributed to a wide variety of factors including the island’s shape and the natural vegetation.
