##### Tidal modelling
Having read the documentation, I understand how the tides ini file can model the height of tide at any given time.   Is there some way, however of modelling the tidal stream , the set and rate of a tide (direction it flows in and the speed that it flows) ?  I was thinking about something like this ...........

if a rising tide sets (flows in at a "heading") of 100 degrees and flows out at 280 degrees
tidal_axis = 100 {the heading of a rising tide}
max_rate = 4  {the maximum speed of a tide}

so speed of a tide at any given time  max_rate * sin (offset + tidal period)
the -ve speed then pertaining to a tidal stream in the opposite direction when ebbing (i.e. 280)

is there an existing way of modelling this ?
