Interactive effect of slope aspect and rainfall intensity on soil permeability compared to acidic rainfalls

Interactive effect of slope aspect and rainfall intensity on soil permeability compared to acidic rainfalls. Environmental Sciences. 19(4): 131-144 sensitivity to soil permeability compared to acid rains. However, the Gachsaran formation showed uniformity changes compared to acidic precipitation and showed positive effects on slope aspect and rain intensity and interactive effect of slope aspect and rain intensity in almost all three concentrations. In addition, by increasing the amount of soil permeated with acid rains, the amount of soil porosity increased, this case was due to this type of contamination on the main ingredients of soil and washing soil bonds. Of course, slope aspect different amounts of clays in both Aghajari and Gachsaran formations, is more influenced by soil permeability than acidic precipitations. The existence of different organic matter in the main aspects of the slopes, especially in the northern and eastern slope aspects, creates a more complex situation in electrical charge changes, which necessitates further research to understand this complex mechanism. Conclusion: In general, by increasing the acidic degree and increasing the penetration time, soil properties were changed, including the resistance characteristics and bearing capacity of the soil, which in turn, due to the amount of clay and different organic matter, caused more influence of acidic precipitation on soil permeability.
