Abstract: It is well known that sea (salt) water intrusion is a natural disaster, and its process follows the law of energy conservation, the law of conservation of momentum and the Newton’s second law. It is not a single linear relationship between sea (salt) water intrusion factors both in the natural state and human intervention state. In this paper, using dimensional homogeneity theory, the mathematic representation of seawater intrusion dynamic balance is made under both natural conditions and typical prevention measure conditions. The foundation factors and key factors under all sorts of seawater intrusion pre-vention measure conditions are proposed, and the dimensionless relationship between the foundation factors and key factors is built. The result shows that different artificial control projects correspond to different key indicators, and the dimensionless relation indicates that the water curtain migration time distance and fresh water injection flow present a good regularity. The dimensionless relation will also provide a technical support for seawater intrusion prevention and research in the future.
