Tidal modeling is divided into two areas: physical scale modeling and mathematical modeling. Physical modeling entails developing, constructing, verifying, and testing a scale model of a prototype. Mathematical modeling entails the same steps for a set of mathematical and/or logical expressions whose solution, usually on a digital computer, yields the desired parameters. The modeling technique and solution method for a specific problem are determined by the problem itself, the type and precision of desired results, and available personnel and physical resources. Three specific applications of physical models are discussed: a study of the feasibility of renovating and maintaining three dikes in Delaware Estuary, a study of flushing characteristics of San Diego Bay with various second entrance plans, and a study of salinity intrusion in Delaware Estuary. Mathematical models are discussed, with emphasis on mathematical models for predicting one- and two-dimensional tidal flows. Specific examples are the Chesapeake and Delaware Canal and a general surge study at WES. Physical and mathematical modeling techniques each have certain advantages. Extensive employment of both techniques at WES shows conclusively that complementary use to resolve different aspects of a comprehensive tidal problem usually provides optimum results.
