The infiltration characteristics of the soil are an important component of the hydrological conditions. They are one of the components of the water balance and are necessary to describe the runoff response by a runoff model, in addition to describe the effect of water movement on the changing of the soil properties within infiltration.
The present work emphasis on the characteristics of the infiltration by using laboratory model. This model is performed on the remoulded sample of specific density for different heads of water, 10, 20, and 30cm. The results revealed that there are significant effect of the water head with high interaction of the wetting conditions of the soil sample. A comparison was made with the results of field infiltration work, made by Mohammed Sh. Al Shakerchy, 2006. A statistical analysis was made to develop a relationship among the different studied parameters and between the field and laboratory works.
