Program Layout 



4. The program CAUDAID consists of two categories of subroutines: 

 graphics screens and dolos design. The program contains five different types 

 of graphics screens: title, data input, plotting menu, plots, and summary. 

 The first screen is the title screen with the program name, the version 

 number, the date of last revision, _ the author, and the publishing authority. 

 The second screen is the data input screen. Values are required for dolos 

 weight, unit weight or weight density, waist ratio, number of layers, fatigue 

 factor, tensile strength, wave height, structure slope, stability coefficient, 

 and design exceedance probability. The default values on this screen are 

 those used for the 1986 Crescent City rehabilitation design, and the values 

 input must be in English units. The choice of metric or English units will be 

 added in a future release. The armor weight may be input as . , in which 

 case the program will compute the stable weight based on the Hudson equation. 

 The user moves on to the next screen by pressing the Fl key, once all of the 

 design values have been entered. 



5. The third screen is the plot selection screen. This is a menu that 

 allows the user to view various plots including waist ratio versus stress, 

 layer versus stress, combined stress probability function, and design 

 nomographs. The selected plot will then appear in the fourth screen. The 

 user can view a summary output screen by choosing the SUMMARY option on this 

 screen or can exit the program by choosing the selection. Again, the user 

 moves to the next screen by pressing the Fl key. 



6. The fourth screen is the plotting screen. This screen allows the 

 user to view the stress relation and design plots and to interactively modify 

 input data and view the results directly on the plots . This screen is the core 

 of the program and can be used to optimize the dolos design for both 

 hydrodynamic and structural stability. The screen has vertical and horizontal 

 menus that provide the user with a wide variety of utilities. These utilities 

 are described briefly in Tables Al and A2 . 



7. The reader will note that the items in the horizontal menu can be : 

 selected by moving left and right using the cursor control keys or by pressing 

 the key corresponding to the first letter of the menu item. Choosing the MENU 

 item on the horizontal plot moves the cursor to the top of the vertical menu 

 at the right side of the screen. The upper portion of the vertical menu is
