Feasibility of groundwater withdrawal in coral island (Lakshadweep)- a paper in hydrological sciences

Groundwater on a small coral island occurs in the form of a lens floating on saline water. The freshwater lens is highly sensitive to various stresses such as pumping, sea tide, etc. Since groundwater is the only source of freshwater on the island, it is not only being utilized for various purposes but also there are growing demands for increased pumping.

The hydrological parameters were  used to construct a two dimensional solute transport model and the effect of additional groundwater pumping on quality of groundwater was studied. The model helped in arriving at a safe groundwater pumping scheme. Feasibility of groundwater augmentation by constructing a subsurface dam was also  demonstrated through this study.
