Macropores are ubiquitous in soils and yet, among the poorly understood flow systems in soils. in saturated flow conditions, macropores create a unique flow fleld. While a part of the macropores shows a diverging flow field, the rest of the macropore shows a converging flow field. This creates drainage issues in soils for water and solutes. The extent of this dipole-like nature of macroporous flow is dependent on the location of the macropore within the soil and its texture. In this study, we analyze this dipole-like macroporous flow behavior using experimental and modeling approaches.
