In the coastal regions it is often necessary to meet the growing water requirements by continuous groundwater withdrawals from coastal aquifers. Excessive withdrawal of freshwater disturbs the dynamic balance across fresh - saline water interface which results in seawater intrusion. This causes deterioration of ground water quality. The main objective of the book is to highlight some remedial measures of seawater intrusion for sustainable utilization of the ground water. A numerical model is developed to study 2-D steady state seawater intrusion problem for single and ...
