GENESIS is a shoreline response numerical modeling system. The model
is adopted as the official shoreline change model of US Army Corps of Engineers.
There are an estimated 1,000 users around the world.

The system has the following properties:

• Accounts for shoreline change by longshore sediment transport gradients
• The longshore extent is about 5 to 100 km
• The temporal extent is about 1 to 20 years
  

Model Capabilities:

• Internal wave transformation module
• Almost arbitrary numbers of groins, detached breakwaters, beach fills & seawalls
• Almost any combination of structures & beach fills
• Bypassing & transmission of sand at groins & jetties
• Multiple diffraction from structures
• Multiple wave trains
• Wave transmission through detached breakwaters
• Tombolo development inside detached breakwaters
• Sediment transport from breaking waves combined with other currents (tidal, wind,...)
• Accounts for pre-specified stable regional or local contours
• Algorithm for variable, time-dependent transmission coefficient

Model Limitations:

• No wave reflection
• No tombolo development
• No provision for changing tide level
• Sediment transport produces by wave-generated currents only.
• Basic limitations of shoreline change modeling theory
