1.0 Introduction Water is one of the most important factors limiting the growth of plants in all Agricultural systems. In this respect, good water management is necessary in order to solve water related problems such as irrigation and erosion control. Infiltration is the process by which water arriving at the soil surface enters the soil. This process affects surface...
