Abstract : This Dredging Operations and Environmental Research (DOER) Technical Note (TN) describes the graphical interface for the Particle Tracking Model (PTM). The Coastal Inlets Research Program (CIRP) and the DOER Program are jointly developing the PTM. The PTM is described in a series of three technical notes. This technical note, Part I, describes the graphical user interface of Version 1.0 of PTM. Part II (Demirbilek et al. 2005a) provides an overview of general features and capabilities of PTM. Part III (Demirbilek et al. 2005b) is a tutorial with examples. The PTM has been developed for application to dredging and coastal projects, including dredged material dispersion and fate, sediment pathway and fate, and constituent transport. A technical report (MacDonald and Davies, in preparation) provides details about the theory and implementation aspects of the PTM. PTM methodology is based on a parcel calculation technique, in which parcels represent a given mass of sediment subjected to the same forces and exhibiting the same kinematics as a single sediment particle. Each parcel has its own set of attributes (e.g., grain diameter, specific gravity), which influence parcel behavior (entrainment, transport, settling). The PTM employs a Lagrangian particle tracking technique to estimate migration of sediment particles as influenced by the hydrodynamic forcing inputs, including current velocity and wave fields. This approach compliments the Eularian sediment transport and morphological models, and can provide information about a specified subset of sediment processes. This information may be applied in projects without the more resource-intensive application of a Eularian sediment transport model.
