A tidal stream (or tidal current) is an alternating horizontal movement of water associated with the rise and fall of the tide caused by tide-producing forces. (IHO Dictionary, S-32, 5th Edition, 1169)
Predicted tidal stream rates may be calculated using time and rate differences with respect to a reference station (and associated tidal stream predictions).

The object 'tidal stream - non-harmonic prediction' encodes information for use when predicting times and rates for tidal streams by non-harmonic methods.
The supplier of any parameters must be consulted on how to use this data, and which calculation algorithms to use with the data.
