When Projecting Coastal Resilience, Sediment Compaction Is Key

by Morgan Rehnberg 30 September 202230 September 2022

The addition of new sediment helps build up lowland environments like deltas and marshes, but it also compacts materials beneath it—a vital, but often overlooked, factor in landscape evolution studies.

A bright red, orange, and yellow thermal image of London and the surrounding area maps hotter and cooler areas of the city. The center of the image is the city of London, which is yellow, indicating that it is hotter than surrounding suburbs, which appear in varying shades of orange and red. The suburbs tend to become cooler, and appear darker red, moving toward the edges of the image. The River Thames snakes from right to left across the center of the image. It and several water reservoirs to the left of center are black, indicating that they are much cooler than the neighboring land.
