Drainage refers to the removal of surface or subsurface water by natural or by installing artificial drainage systems. Drainage helps in lowering the water table and reducing the risk of rising groundwater table and accumulation of salts through the capillary rise. Hence, it is necessary to have a proper drainage system in order to reduce the negative impacts of rising water table and accumulation of salts. It can be accomplished by establishing surface (through ditches) and subsurface drainages (through open ditches, mole drains) (Shahid et al. 2018).
