Litpack (Littoral processes and coastline kinetics) is simulation software for coastal sediment transport. The software is an industry standard model for one-line shoreline change. Litpack is developed by DHI.
Research
An Army Corps of Engineers study compared this program to two others, GenCade and Unibest. The study found "notable differences" in predictions of shoreline change models.
