A mathematical model of the movement of fresh and salt waters in coastal aquifers in which fresh water is withdrawn by wells is presented. The location of the fresh-salt water interface in artesian and unconfined aquifers is determined on the basis of analysis of hydraulic forces in the body of fresh water. The 3-dimensional flow systems are developed by analogy to 2-dimensional finite-length systems. Dupuit-Forchheimer assumptions are entirely climinated. A Hele-Shaw model was constructed to study 2 dimensional flow of 2 immiscible fluids of different viscosities in transient and steady flow. Salt water intrusion was studied combining the effects of natural flow and multiple well pumpage.
