From the developer:
GasSimLite is fully functioning freeware based on GasSim which is designed to help landfill operators submit their Pollution Inventory responses to the Environment Agency. The main screen shows a cartoon, which guides you along the process of defining the source term, the gas management options, details of the contaminant transport pathways (from the source to the various receptors).
