Abstract
The research conducted at Hazrat al-Fadil one of the south Mosul villages in Qayara, With three arrangements including the rectangular (9m×12m), The isosceles triangle (12m×12m) and (11m×13m) . The calculated uniformity coefficient have (85.25%) for the rectangular arranging (9m×12m) and (85.67%) , (87.13%) for the isosceles triangle (12m×12m) , (11m×13m) respectively. The calculated distribution uniformity for the lowest quarter have (79.82% , 79.44% , 81.05%) for the rectangular (9m×12m) and the isosceles triangular (12m×12m) , (11m×13m) respectively. The calculated Values for the water addition rate under the three arrangements have Convergent for isosceles triangle (12m×12m) , (11m×13m) have (0.48) mm.hour-1 , (0.49) mm.hour-1 respectively, While the water addition rate value was higher under the rectangular (9m×12m) as it have (0.64) mm.hour
