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 is operated within the Surface-water Modeling System (SMS) 11.1 interface and higher SMS. The model 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.

The GenCade interface is undergoing an overhaul and is presently being developed for SMS 13.3. This new interface will be available later this year (2024) and an update to SMS 13.3.

Several workshops have been conducted over the years to instruct new users and to highlight new model features:

  • February, 2011 - Jacksonville, Florida - Inaugural GenCade workshop.
  • August, 2011 - San Diego, California - Full day including demonstrations and hands-on examples
  • March, 2012 - Philadelphia, Pennsylvania - Full day including demonstrations and independent student activities
  • October, 2012 - First GenCade webinar - 3 days of instruction divided into 2-hour daily sessions. Included model setup using SMS.
  • November, 2018 - Detroit, Michigan - 1 day hands-on for GenCade as part of CMS/GenCade training to the Detroit District.
  • May, 2019 - Tampa/St. Pete, Florida - Full day training workshop during the 9th International Conference on Coastal Sediments
  • November, 2020 - GenCade webinar - Tutorials and example files can be found at
