TrackMPD v.3.0 uses the reference system of the hydrodynamic model instead of the previous system of TrackMPD, which was relative to the water surface. This new reference system avoids an error in the advection calculation which was only significant when applying the model to shallow waters with quick changes in water level (e.g. wave-dominated environments).
Other new features in TrackMPD v3.0 include:
New parameterizations for resuspension as in version 2.3 only a parametrization adapted to wave-dominated environments was included
Water level over the particle's position is now saved in the output file
New beaching calculation to save computational resources and avoid incompatibilities between the domain file and the hydrodynamic model domain.
