Abstract

In order to study the effect of super absorbent on runoff volume in slopes and various intensity of rainfall research was accomplish according to split – factorial blocks method with main treatment and two accessory treatments in three replicate . the main treatment consist of three dominant slopes (10 , 20 , 30 percent ) and accessory treatments consist of five levels of substance super absorbent ( instance , 20 , 40 , 60 , 80 kg/ha ) and three levels of various rainfall intensity (25, 30,40 mm/hr). the rain simulator set was used and the rainfall duration intervals was 30 minutes. To establish hydraulic pressure complementary water volume added to reservoir tank in each 5 minutes. Then runoff was gathered to measure output runoff volume. Finally statistical analysis was done on the collected data. Results shows that substance super absorbent treatments of various rainfall intensity in comparison with control plate has significant effect in decrease of output runoff volume to 5 level percent.
