Effects of Coal Gangue Content on Water Movement and Solute Transport in a China Loess Plateau Soil.

The article discusses a study which examined the effects of coal gangue contents on infiltration, saturated hydraulic conductivity and solute transport parameters of a Chinese Loess plateau soil. Gangue refers to a waste residue from coal mining and coal washing. Findings revealed a decline in infiltration rates and saturated hydraulic connectivity as gangue content increases. The solute transport processes have been described by the simplified convection-dispersion equation and a two-region model.
