Mitigation of seawater intrusion through managed aquifer recharge in southeast India - DHI Case Story
Application of coupled surface and groundwater modelling in a coastal aquifer
The water supply system of the metropolitan area of Chennai is facing problems due to high groundwater abstraction and progressing salt water intrusion. To increase groundwater recharge, several check dams have been constructed in this area. A supporting analysis and planning tool has been developed for long-term analysis of managed aquifer recharge (MAR) measures. An increase in groundwater levels was verified, but a reduction of the current abstraction rate is necessary for a sustainable management of the water resources.
