engineers , some material is repeated in the different contexts to allow both 

 groups to achieve understanding of the modeling system. 



15. The second function of this report is to serve as an operating 

 manual for GENESIS, including practice in implementing its principal features. 

 Part VI begins the manual portion and concerns the structure and use of the 

 interface consisting of input files and output files. The potential of 

 GENESIS is demonstrated in Part VII through simple examples that show various 

 combinations of capabilities of the modeling system. Part VIII presents a 

 realistic case study that draws on theory and practice developed in 



Parts V-VII. 



16. Appendix A gives a review of the literature dealing with GENESIS 

 and its predecessor, covering model development, tests, case studies, and 

 findings of general interest. Appendix B contains blank input files, which 

 may be photocopied in preparatory work for running GENESIS. Common error 

 messages and suggested recovery procedures are given in Appendix C. Input 

 files for the case study are given in Appendix D. Notation used in this 

 report is listed in Appendix E. Appendix F is an index. 



17. The present report documents Version 2 of GENESIS. It is antici- 

 pated that additional volumes will provide updates on improvements of GENESIS 

 that lead to significant enhancements and new versions of the shoreline change 

 modeling system. Report 2 in the series is scheduled to be a workbook for 

 power users of GENESIS and will be referred to as the "GENESIS Workbook." The 

 GENESIS Workbook will be a toolbox containing computer routines developed for 

 preparing and analyzing data in conjunction with GENESIS. It will also 

 describe analysis strategies and provide more detailed information on the use 

 of an external wave transformation model with GENESIS than was possible here.
