Macropores constitute around 5% of the total soil pores, but account for 70-80% of water and solute movement. Despite their importance, the existing studies in India mostly ignore their effect while modelling water and contaminant movement in subsurface. This study proposes to develop a modified model for flow through macropores based on numerical and experimental analysis.
