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.
