What is LandSim?

An interactive program developed by Golder Associates on behalf of the Environment Agency, LandSim uses Monte Carlo probabilistic performance assessment models constructed for new and existing landfill sites.

The model essentially tracks leachate production, chemistry, migration and leakage through engineered and non-engineered structures, followed by leachate migration through the unsaturated zone to assess the ultimate impact on the aquifer.

LandSim 2.5 is supported on Windows XP and earlier Windows operating systems but has not been tested on Windows 7, 8 or 10.

An accompanying Distance Learning Package for LandSim 2.5 comprising audio lectures and self-study workshops is also available.
