Managing acidity movement in the coastal land with acid sulphate soils: a modeling approach

摘要

A new acidity module has been developed and coupled successfully into an existing hydraulic and salinity model for simulating acidity movement in canals under the controlled marine water intake in the coastal land with acid sulphate soil (ASS). The model allied with the Camau peninsula, Mekong Delta, Vietnam indicates that the most suitable option for improving the acidity condition is to open main sluice gates one day every week when difference of tide amplitude of between the East and West seas ishighest and to widen the canals connected to the West sea.
