Try:

  Unit cycles = CommonUnit.dimensionless.divide(CommonUnit.second);
  Unit hz = cycles.clone("Hz");
  RealType count = RealType.getRealType("count", hz);

I am not sure what you mean. To change Rivers.java from two to
three dimensions, change 'RealTupleType earth' to use three
component RealTypes, and change the Gridded2DSets to
Gridded3DSets.

Good luck,
Bill
