erosion

The safety of earthen embankments, including levees and dams, depends in large part on how resistant they are to erosion.

That resistance can hinge on the soil materials used in their construction.

Cavities or not, your teeth could be in more trouble than you know because of a silent and destructive phenomenon called dental erosion.

Scientists have found that the incidence of dental erosion, which is the steady loss of the teeth's protective enamel, is on the rise in the United States.

Soils under desert pavement have an unusually high concentration of nitrate, a type of salt, close to the surface.

Vulnerable to erosion by rain and wind if the desert pavement is disrupted, this vast source of nitrate could contaminate surface and groundwaters, posing an environmental risk.
