Conclusions 



34. The shoreline change numerical model is the only general purpose 

 engineering model presently available for wide application in simulating long- 

 term evolution of the beach plan shape. This type of model provides a 

 framework for performing a time -dependent sediment budget analysis under a 

 wide range of situations encountered in shore-protection projects and requires 

 only generally available or estimated input data. With the advent of GENESIS, 

 the potential of the shoreline change model has reached a stage where it can 

 be operated without expertise in numerical modeling. Numerous refinements can 

 be expected as the model is tested and adapted to include other phenomena and 

 engineering activities responsible for causing long-term beach change.
