19 ABSTRACT (Continue on reverse if necessary and identify by block number) 



This report documents a numerical modeling system named GENESIS, which is designed 

 to simulate long-term shoreline change at coastal engineering projects as produced by 

 spatial and temporal changes in longshore sand transport. The name "GENESIS" is an 

 acronym that stands for GENE ralized Model for Simulating Shoreline Change. Typical 

 longshore extents and time periods of modeled projects can be in the ranges of 1 to 

 100 km and 1 to 100 months, respectively, and almost arbitrary numbers and combinations 

 of groins, detached breakwaters, seawalls, jetties, and beach fills can be represented. 

 GENESIS contains what is believed to be a reasonable balance between present capabilities 

 to efficiently and accurately calculate coastal sediment processes from engineering data 

 and the limitations in both the data and knowledge of sediment transport and beach 

 change .
