Evapotranspiration and depth to water table

I'm modeling a shallow aquifer with very little depth-to-water table (DTWT), so I would like to consider groundwater evapotranspiration (GWET) depending from depth-to-w.t..
I calculated a potential ET time series (with Penman-Monteith formula); how can I put corrective coefficients, depending from DTWT, in my FEFLOW 5.1 model?
I saw there was this link in wasy.de site, but it's broken...
http://www.wasy.de/english/produkte/feflow/howto/video_evapotranspiration.htm
I saw this link also in yahoo India - feflow user group:
http://in.groups.yahoo.com/group/feflow/message/108

The new link is http://www.feflow.info/320.html. However, this will not work in FEFLOW 5.1.

I tried to look at this link, but I can't see anything...
should I have a specifical plugin to watch this video?
Thank you,
Alessandro

You'll need a flash player to see the animation.
