%X In order to evaluate the effect of slope on wetting pattern using a linear water supply a study has been taken in research field during the fall of 2014, at Shahid Chamran University of Ahvaz, Iran. In this research two flow rates 6 and 9 liters per hour per unit length, three slopes, including 0, 2 and 5 percent with three replications at the randomized block design were used. The soil texture was silt loam. The results of statistical analysis showed that with increasing discharge and slope, width and depth, area and volume soaked increases. The results showed these differences are significant in 1% level for 2 and 5 percent slopes compared to 0. Increase width soaked in for the rate of 6 liters per hour in slope of 2% with compared to a 0, 10 percent and for slope 5%, was 20 percent. Also the increase for width in the rate of 9 liters per hour respectively was 3 and 13 percent. Increase depth soaked in for the rate of 6 liters per hour in slope of 2% with compared to 0, 12.5 percent and the slope of 5%, was 25 percent. Also the increase for depth in the rate of 9 liters per hour respectively was 17 and 35 percent. Increase area in for the rate of 6 liters per hour in slope of 2% with compared to a 0, 24 percent and for slope 5%, was 56 percent and for flow rate of 9 liters per hour the increase for area, respectively was 28 and 45 percent.
