ABSTRACT 



A quasi-two-dimensional numerical model for open-coast storm-surge computa- 

 tions is discussed from the standpoint of underlying assumptions, range of validity, 

 calibration, and application. While it is possible to make computations manually, 

 electronic digital calculations are generally preferred. Elementary aspects of 

 hurricanes and the physical factors of storm-generation processes are discussed. 

 The basic hydrodynamic equations are given, together with the assumptions generally 

 made in their development. The equations consistent with the model 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 astro- 

 nomical tide, initial water level, and atmospheric-pressure setup are considered. 

 A problem is solved for the Chesapeake Bay Entrance by computer and manually. The 

 computer program used is listed.
