compilation of a matrix of beach change volumes at various sections of the 

 coast by which the technical solutions could be ranked. Economic consider- 

 ations were then used to arrive at the most feasible project plan. 



Step g 



49. In addition to aiding in the evaluation and optimization of project 

 designs, shoreline response modeling can provide guidance for preparing a 

 monitoring plan (Step g) . Regions of anticipated maximum and minimum shore- 

 line change or sensitivity can be identified and the monitoring plan struc- 

 tured to provide data in these important regions. Initial estimates of the 

 monitoring schedule (frequency of measurements) and density or spacing of 

 measurement points can also be made by reference to model predictions. 



Conclusions 



50. Because of their great power and generality, shoreline change 

 numerical simulation models such as GENESIS provide a framework for developing 

 shore-protection problem and solution statements, for organizing the collec- 

 tion and analysis of data, and, most importantly, for evaluating alternative 

 designs and optimizing the selected design. Numerical models of beach 

 evolution extend the coastal experience of specialists and introduce a system- 

 atic and comprehensive project management methodology to the local engineering 

 or planning office. 



51. This chapter has attempted to demonstrate the utility and benefits 

 of numerical modeling of coastal processes to the coastal planning and 

 management community. Although emphasis was on numerical modeling and beach 

 processes, it should be recognized that planning and design of a shore- 

 protection project will involve a wide range of techniques and tools.
