This paper reviews the basic concepts and modelling approaches of now and solute transport phenomena in groundwater modelling studies. The theme attains significance due to the adverse effects caused by saltwater intrusion in coastal aquifers due to overdraft and other aquifer stress conditions caused by the developmental activities. A good number of groundwater models are commercially available for use, of which commonly used models which are capable to simulate 3 dimensional flow and transport are presented. Also, the basics of governing equations of flow and transport used by the SEAWAT model are highlighted. A brief discussion on data required and steps involved in the simulation process arc discussed. In view of all these facts, groundwater modelling has emerged as a tool to understand and visualize all the complexities involved in groundwater management. Availability of user friendly softwares, have made the task even easier. Since, the whole process involves complicated numerical solutions, solving them manually would be rather difficult. However, the challenge still remains in understanding the mathematics involved in the development of software, customizing the data to the requirement of the identified problem, calibrating and validating the model and applying the same to various groundwater management problems considering future stress scenarios. The paper makes an attempt to review the state of the art transport models useful for the simulation of coastal aquifers.
