record shows that some period after leveling of the dumped soil, erosion of the slope occurred.
To overcome this, geotextile tubes can be used to protect coastline from waves and tides—as
has been utilized in some countries. The tubes, which can be installed along the coastline, are a
few meters in diameter and a few kilometers in length can be illed with dredged soils (Figure
8.22). They can also serve as a breakwater for man-made islands and wetlands.
