Abstract
This report studies the following problems.
1) To examine the effect of geology and topography as the controlling factors on groundwater flow systems.
2) To research the behavior of pollutants in the porous media concerning to groundwater flow systems.
In the first subject the author discusses that how far the effect of geologic and topographic conditions extend on groundwater flow pattern. An example is summarized in Table 1.
In the second subject he emphasizes that the sedimentary facies, many types of heterogeneous configurations and interlayered clayey deposits are important as the controlling factor on the behavior of pollutants. A few of his recent studies are introduced in this paper.
