Bottom shear stress

Hei. I tried to get out the modelling results for bottom shear stress (SB) but I can't find it somewhere in the output files of CE-QUAL W2. Does somebody the location where it`s written out? (I set up the SB button in control file to "on") The users manual tells me that the unit for bottom shear stress should be m^3/s^2 (see e.g. table C-8 on page C-82). But I don`t understand how this unit comes. If I am right that calculation is made by equation A-147 (page A-59). But the units in this eq don`t lead me to m^3/s^2. At least the mass from water density should be somewhere and couldn't be canceled down I think. Actually I expected a unit similar to N/m^2. I hope somebody can help me to understand how the model works. Thax! Christoph. ... In the mean time I've found out how to write out the modelling results of bottom shear stress. Now it's just the question how the unit comes to m³/s²? I'd be lucky to get a reply. Thanx!
