Since the transformation is conformal, the associated modifications of the 

 vertically integrated equations of motion and mass continuity are minimized. 

 The coast, seaward boundary, and the lateral boundaries of the computing grid 

 are straight lines in the image plane thus facilitating the application of the 

 boundary conditions. The final coordinates allow for the greatest resolution 

 near the coast in a central area of principal storm surge development and 

 modification. 



The model is employed in the simulation of the storm surge induced by 

 Hurricanes Carla (1961) and Camille (1969) which crossed the gulf coast of the 

 United States and Hurricane Gracie (1959) which crossed the east coast. Ana- 

 lytical interpretations of the wind and atmospheric pressure-forcing functions 

 are used in the computations.
