In the description of a soil deposit and a contaminant source (eg. a landfill) the values of all the input data are not always known with certainty. For example, the length of time that the primary leachate collection system will function before becoming clogged [Rowe and Fraser, 1993a, 1993b]. However, if the minimum and maximum values of the parameter can be estimated then Sensitivity Analysis can be used to predict the expected range of contaminant concentrations.
This feature is vary similar to Monte Carlo simulation; except, that when performing a Sensitivity Analysis only one variable may be evaluated at a time.
To use this feature select the Sensitivity Analysis menu item from the Special Features menu. The Sensitivity Analysis form will be displayed. This form has two tabs, one for the general data and one for the variable data.
