I think that is a great strategy to consider for removing water from 
year round waterlogging, or even seasonal waterlogging in warmer climes. 
I do have American sycamore -- /Platanus occidentalis/, a tree often 
found in riparian and wetland areas -- that crop up as seedlings on my 
high sloping ground. However, my waterlogging does not occur in the 
growing season. This is probably in part due to the water uptake by 
trees.  I am also growing the fabulous black locust -- /Robinia 
pseudoacacia/, a leguminous tree which coppices well and whose wood is 
excellent for posts, lumber, and a high BTU firewood. Further it is an 
excellent honey plant for my bees. But, there again, they  do not 
evapotranspirate during my wet system season, which also is a period of 
cold weather and dormancy.

Willows are a very diverse family of plants that is comprise of 400 
species that have a multiplicity of uses. I grow curley willow -- Salix 
matsudana -- on my farm. Other native willows haved moved in to 
participate in the ecological succession around my pond, but I have not 
keyed them out yet.
