Abstract

This study was performed to investigate the effect of Polyacrylamide (PAM) on pattern of variation of runoff components consist of the amount of runoff during rainfall, cumulative runoff, the runoff commencement and cessation time and runoff amount at different time steps. The experiments were taken place in Soil Erosion and Rainfall Simulation Laboratory. In this study, three small cubic plots with dimensions of 0.5 m, total volume of 0.125 m3 and having 20% slope were used. The conducted experimental treatments were consisted of 0 (control), 0.4, 0.6, 1, 2, 3, 4 and 6 g PAM/m2. The results indicated that the PAM-treated plots had no significant reducing influence on runoff amounts (P=0.49). The reduction of runoff amount at different levels of PAM had also no specific trends. In addition, the maximum reduction in total runoff occurred in treatments 2, 6 and 1 g PAM/m2, respectively. The runoff commencement time was increased by increasing the amount of PAM to 2 g/m2 and runoff cessation time was decreased due to increasing amount of PAM level to 1 g m-2, respectively. The assessment of runoff amount in common time steps of different treatments also revealed that the different amount of PAMs had no significant effect (P>0.12) on RUNOFF CONTROL in all steps except the first and third time steps.
