CONCEPTUAL AND NUMERICAL SIMULATION FOR CONTROL OF SEAWATER INTRUSION: A REVIEW

K. Jananee, N. Karthika, V. Murugaiyan

Abstract :

Sea water intrusion is the migration of seawater into freshwater aquifers due to over exploitation of groundwater. The most detrimental effect is that ground water depletion causes lowering of water table and also changes in fresh / saltwater interface. Therefore seawater intrusion should be controlled to protect groundwater resources. Methods for controlling intrusion varies depending on the source of the saline water, the extent of intrusion, geology, water use and economic factors. This review paper presents study on different methods proposed for simulation and optimization in both confined and unconfined aquifers. From the analysis, it was observed that ANN is an economically best model to analyse and ADR provides cost effective methodology for seawater intrusion. Also a coupled density–dependent finite element model developed for simulation of fluid flow and solute transport which has been integrated with an optimization model (GA) gives best results.
