Summary


GenCade is a one-line shoreline simulation model that combines the capabilities of regional-scale, planning-level calculations of CasCade and project-scale, engineering design-level calculations of GENESIS. GenCade computes shoreline change and wave-induced longshore and cross-shore sand transport. It has been operated within the Surface-water Modeling System (SMS)

  • GenCade version 1.x was officially released in April 2012 and SMS 11.1 was released in October 2012. Publications for GenCade, including technical reports, notes, tutorial materials (video clips and presentation slides) can be found on the CIRP website GenCade page.
  • Wiki pages for GenCade version 1.x can be found here.

The GenCade interface has undergone many changes and improvements and being developed for SMS 13.3 and later. Most of the changes have come in the actual SMS interface for the setup for the GenCade simulations using a new Dynamic Model Interface in the SMS which allows for faster integration of updates and new features. Other changes to GenCade have been as new features implemented in the actual GenCade mode, such as Cross-Shore sediment transport and the ability to perform a series of Monte Carlo simulations.

A few workshops have included a demonstration and information transfer showing the new GenCade Cross-shore transport and Monte Carlo features, but did not cover any changes to the SMS interface. These were:

  • September, 2022 - Mobile, Alabama - Full day workshop highlighting new cross-shore transport feature and Monte Carlo simulations.
  • June, 2023 - Los Angeles, California - Full day workshop highlighting new cross-shore transport feature and Monte Carlo simulations.

The upcoming CIRP Workshop in Buffalo, New York in November 2024 will also cover the new GenCade features, but there will also be demonstration of the new SMS interface. It is our hope that all users will have access to the new interface in Q2 of FY25.
