ABSTRACT
This chapter focuses exclusively on modeling and the application of data derived from the soil columns for predicting pollutant movement through soils. Physical models are also a possible means of evaluating a waste disposal system. One of the major problems using mathematical models in general and the Lapidus-Amundson model in particular is that of estimating meaningful values for the unknown parameters. The downward movement of a polluting metal through soil can be expressed in terms of the vertical velocity of a relative concentration. It is assumed that the velocity of each relative concentration reaches a constant value within a relatively short distance from the point of pollution. Multiple regression is a statistical technique through which the relationship between a dependent variable and a set of independent variables can be analyzed. After the velocities are found a multiple regression analysis is performed using the properties of soils and leachates from the laboratory column experiments.
