Line A. 4, the appropriate values will be read from these files. This error 

 message will appear if the end of the DEPTH file or WAVES file is prematurely 

 encountered and is remedied by adding more values to the two files, changing 

 the value of total number of calculation cells on Line A. 3, or changing the 

 grid cell numbers where the calculation starts and/or ends on Line A. 4. 



15. ERROR FOUND IN KDGODA. KD CALCULATION DID NOT CONVERGE. The 

 diffracted breaking wave conditions are found by a search method that normally 

 converges within 5 to 10 iterations. However, to avoid the risk of being 

 trapped in an infinite loop, which, for example, can happen if the shoreline 

 advances past a detached breakwater, the search is stopped after 20 itera- 

 tions. This message will appear if the search procedure has not converged 

 within 20 iterations, and if the error persists, it probably signals a signi- 

 ficant flaw in the wave, depth, or structure configuration input data. 



16. ERROR FOUND IN SHOIN. FILE SHORM CONTAINS TOO FEW VALUES. 

 Following specification of the total number of calculation cells on Line A. 3 

 and of the grid cell numbers where the simulation starts and ends on Line A. 4, 

 shoreline positions will be read from the data file SHORM in the subroutine 

 SHOIN. This message will appear if the end of the SHORM file is prematurely 

 encountered and is remedied by adding more values to the file, changing the 

 value of the total number of calculation cells on Line A. 3, or changing the 

 grid cell numbers where the calculation starts and/or ends on Line A. 4. 



17. ERROR FOUND IN SHOIN. LAST SHORELINE BLOCK(S) OUTSIDE THE CALCU- 

 LATION GRID. Following specification of the total number of calculation cells 

 on Line A. 3 and of the grid cell numbers where the simulation starts and ends 

 on Line A. 4, shoreline positions will be read from the data file SHORL in the 

 subroutine SHOIN. This message will appear if the end of the SHORL file is 

 prematurely encountered and is remedied by adding more values to the file, 

 changing the value of the total number of calculation cells on Line A. 3, or 

 changing the grid cell numbers where the calculation starts and/or ends on 

 Line A. 4. 



18. ERROR FOUND IN SWLIN. FILE SEAWL CONTAINS TOO FEW VALUES. 

 Following specification of the total number of calculation cells on Line A. 3 

 and of the grid cell numbers where the simulation starts and ends on Line A. 4, 

 seawall positions will be read from the data file SEAWL by subroutine SWLIN.
