Multimedia Leaching Assessment Model

MULTIMED, Multimedia Assessment Model, is a user-friendly model which simulates the fate and transport of contaminants leaching from a waste disposal facility into the multimedia environment. Release to either air or soil including the unsaturated and saturated zone and possible interception of the subsurface contaminant plume by a surface stream are included in the model. MULTIMED includes two options for simulating leachate flux. Either the infiltration rate to the unsaturated or saturated zone can be specified directly or a landfill module can be used to estimate the infiltration rate. The landfill module is one-dimensional and steady state and simulates the effect of precipitation, runoff, infiltration, evapotranspiration, barrier layers (which can include flexible membrane liners), and lateral drainage.

Multimed is DOS program. Please review our other unsaturated flow and transport software for updated Windows-based products.

MULTIMED has bee replaced by MULTIMED for Windows.
