Consequently, the road surface can become flooded or the road embankment can act as a dam, creating flood conditions upstream of the embankment. Similarly, bridges could flood if the volume of water in the flood flow is greater than the volume of water that can reasonably pass underneath or around the bridge at ordinary velocities.

Typically, these vertical sand columns have diameters ranging from 30 to 60 cm and are spaced 2.5 to 6 meters apart in a hexagonal pattern. At the base of these drains, a horizontal sand blanket, approximately 40 to 60 cm thick, is installed, extending across the entire width of the embankment.

This would include trees that could damage upstream slope protection and trees on a crest where uprooting could leave less than a 10- or 19-foot width of undamaged embankment. Trees on or near a downstream slope should be removed if their root systems can penetrate significantly into the minimum necessary embankment cross section.

Soft Rock and Shale Embankments. In embankments composed of rock fill with rocks that weather quickly, there is a potential for the rocks to become soil. As a consequence, these materials could fall into the spaces between the rocks — leading to significant settlement of the embankment, and ultimately, slope failure. It is for this …
