Feature arcs created in a PTM type coverage can be used to create either sources or traps.

- Source ID
- Name
- Show Coordinates in Spreadesheet
- Date/Time
- Parcel MAss – Each parcel represents a specific amount of sediment. Combined with the rate PTM computes the number of parcels being tracked. When a specific quantity of material is being generated by a dredge or other source, this amount allows the tracking of all of that material.
- Radius – PTM will distribute the parcels generated for this source randomly along the line. The position will also vary around the line within this specified radius.
- Rate – A specific quantity of sediment will be generated based on this rate. The longer the line, the more sediment is added to the flow field.
- Median Grain Size – This is the d50 of the sediment being added.
- Standard Deviation – This phi unit defines how the grain size varies from one parcel to the next.
- Density – This is the density of the sediment. This can be reduced to the density of water to create neutrally buoyant particles.
- Fall Velocity – This is the speed of descent of the particles. The shape of the particle influences this quantity. Entering a value of -1 tells PTM to compute this value.
- Critical Shear Intiation – Specifies the shear values to initialize motion for this particle.
- Critical Shear Deposition – The threshold for this particle to settle.
