Abstract: Abstract: Open-coast' storm-surge computations are of value in planning and constructing engineering works in coastal regions.. A quasi-two-dimensional numerical model for such computations is discussed from the standpoint of the model's underlying assumptions, range of validity, calibration, and application. When using simple numerical schemes of this sort., it is possible to make computations manually, although electronic digital calculations are generally preferred. Elementary aspects of hurricanes and the physical factors governing storm generation processes are discussed. To display the principle characteristics of the model from a physical as well as a mathematical point of view, the basic hydrodynamic equations are given, together with the assumptions generally taken in their development. The equations · consistent with the model described here are reduced forms of the basic equations in which several terms have been neglected. These omissions are indicated, and their effects on the resulting numerical scheme are discussed. The use of design hurricanes for engineering studies is treated. Effects of astronomical tide, initial water level, and atmospheric-pressure setup are considered. An open-coast storm-surge problem is solved for the Chesapeake Bay Entrance near Norfolk, Virginia. Calculations are made both by computer and manually. The computer program used is listed.
