Robert:

My system has one outlet and that outlet is controlled by tide. The identifier I used for it is 2 as number. I have setup the first lines of the ascii file as

1 0
2
2003 1 1 17. 0 -0.1
2003 1 1 17.25 0.0
2003 1 1 17.5 0.01
...
etc...

Because following what I understand from EXTRAN DOC line 1 is 1 out let with 0 other outlets affected by tidal data, line 2 is the name of the outlet 2, and I don't need the third line shown in your example so I go directly to tide data as year, month, day, hour in decimal, tidal elevation.

The model runs but I get 0 flows, but if I use the option 5, same data I get flows into and out of the system.Is there something wrong with the set up of the ascii file?

Thanks for your help,
