What is the
difference between
Weathering and
Erosion?
Movement!
When we build
we have to consider
weathering and erosion

Engineering Erosion
Compiled by Rhonda Hawley, Educator
Funded by the
MathScience Innovation Center
The job of the Civil Engineer is to
plan, slow down, and even STOP!
the rock/soil from moving in areas
where people live and work.

Slide 6 & 16 are video clips taken by Dr. Echol Marshall from the
MathScience Innovation Center.
Slide 28 : Where is EcoGrid used?
EcoGrid can be used as either a temporary or permanent ground
reinforcement. It is used to reinforce lawns and other grassy areas to
prevent mud and damage to the ground. Once laid ecogrid can be filled
with stone, earth or seeded. When the grass has grown EcoGrid
becomes invisible but still resists wear and compression.
Ecogrid is perfectly suited to pathways, parking lots or driveways and
has numerous sporting applications such as equestrian facilities and
golf courses. EcoGrid is provides excellent ground support and
prevention from erosion.
