Performance of GCLS in liners for landfill and mining ...
· Liners in landfill and mining covers/caps have exhibited both good and poor performance over the years. If intact, GMBs are excellent barriers to the advective migration of fluids (liquids and gases), but once they have holes or openings (, due to inferior welding), they can readily transmit relatively large volumes of fluid through the hole(s), and it is for this reason that they are ...

Gravimetry
Gravimetry is a potential field technique which measures variations in the Earth's gravitational field. These variations are caused by density contrasts in the near surface rock and sediment. Gravimetric surveys are carried out using extremely sensitive instruments capable of measuring tiny variations in the gravitational field.
