The Particle Tracking Model (PTM) is a Lagrangian particle tracker designed to simulate particle transport processes (McDonald et al 2006, Lackey and Smith 2008, Gailani et al. 2016). PTM models particles which represent passive, sediment, and biological constituents. PTM has been developed for application to dredging and coastal projects including dredged material dispersion and fate, sediment pathway and fate, and constituent transport. The model contains algorithms that appropriately represent transport, settling, deposition, mixing, and resuspension processes in complex wave/current conditions. PTM is a part of the Surface Water Modeling System (SMS) which makes visualization and analysis easy and effective.
