PREFACE 



This report is published to provide coastal engineers with the results 

 of a study to develop an operational program for numerical simulation of 

 storm surges on a given segment of the Continental Shelf, using a curvi- 

 linear coordinate system. The report consists of two volumes. Volume I 

 discusses the theory and application of the transformation procedure for 

 generating the curvilinear shelf coordinate system for particular regions, 

 and the theory, numerical algorithm, and application of the storm surge 

 program for simulation of Hurricanes Carla (1961), Camille (1969), and 

 Gracie (1959). Volume II presents the program documentation and the coded 

 programs for carrying out the coordinate transformation (CONFORM), for 

 establishing the spatial lattice (GRID), and for carrying out the storm 

 surge calculations on the shelf (SSURGE) . The work was carried out under 

 the wave mechanics program of the U.S. Army Coastal Engineering Research 

 Center (CERC). 



Volume I of the report was prepared by John J. Wanstrath (who also 

 authored Volume II), Robert E. Whitaker, Robert 0. Reid, and Andrew C. 

 Vastano, Department of Oceanography, Texas ASM University, College Station, 

 Texas, under CERC Contract No. DACW72-73-C-0014. Most of the computational 

 work in the development and application was carried out at the National 

 Center for Atmospheric Research which is supported by the National Science 

 Foundation. 



The authors express their appreciation to Thomas J. Reid for assist- 

 ance in program coding, and to Dr. D. Lee Harris, CERC, for very con- 

 structive comments on the draft of this report. 



Dr. D. Lee Harris, Chief, Oceanography Branch, was the CERC technical 

 monitor of the report, under the general supervision of Mr. R.P. Savage, 

 Chief, Research Division.
