Comparison of Different Drainage Systems Usable for Solution of Environmental Crises in Soil

Selecting a proper drainage system always has been discussed to solution of environmental crises in soil. In anisotropic soils, this problem is more sensitive for experts. In this study, a comparison has been done between horizontal and vertical drainage in anisotropic soils. For this purpose, using EnDrainWin and WellDrain softwares drain spacing and well spacing, respectively, determined. The results showed that in the same situation, horizontal drainage systems due to the higher spacings between drains (reducing number of drainage and thus reducing the cost) were better than vertical drainage systems. However, vertical drainage systems due to the lower changes in well spacing in different anisotropic soils were suitable for conditions that soil hydraulic conductivity was likely to change
