Theobjective followed in the present study was to investigate runoff generation in soilscontaminated with Kerosene and Gas Oil. Towards this end, variables of runoffcommencement, runoff coefficient, variations in runoff duration time as well ascumulative runoff were determined for the contaminated soils. The experimentaltreatments consisted of two concenterations of Kerosene and Gas Oil.. The resultsindicated that Kerosene and Gas Oil contaminated soil plots significantly influenced thecommencement of runoff, so that, the runoff commencement for non-contaminated plotsoccurred 128 seconds later than that for the contaminated plots. However, different typesof petroleum of the same quantities did not significantly influence the runoffcommencement. In addition, a maximum runoff coefficient was obtained for higherconcentrations of contaminants. The results further indicated that the runoff coefficient incontaminated plots was about 3 to 3.5 times that of non-contaminated plots. Thecontaminated soil plots exerted a significant influence on an increasing of the cumulativerunoff in comparison with the non-contaminated plots. %U https://ijswr.ut.ac.ir/article_54301_d8544855777d0867ebf1beb75f4a5227.pdf
