I need help with building greenhouses on a mountain side with water concerns

I live on the north slope of a mountain in southern Vermont.  In the spring (mud season), we have several vernal streams, and plenty of surface water. I walk through water about 4" deep to get to the raised beds.  I want to build a large greenhouse, or several connected greenhouses, and I have two problems.  I don't know how to build on a slope, and I'm concerned about surface and ground water.  I don't want to create an erosion problem, and I don't want water damage in the greenhouse.  And if I can save some of the water for use later in the summer, that would be even better.  I'm also planning a permaculture section, so understanding our water flow would be important.

I'm asking for recommendations on where to find good information on introduction to hydrology sources (surface and groundwater) and on building a greenhouse on a slope.  

I would also greatly appreciate any and all help I can get on these topics.

How far down to rock?  

You can build a steel hoop greenhouse on a pretty steep slope and build it to let the water through, more like a high tunnel than a greenhouse.  The trick is being able to anchor it down. If you have exposed rock or only a few inches to bedrock, you can get a big hammer drill and anchor your posts directly into the rock.

I'm sorry, I should have explained myself better.  I want to build a glass greenhouse.  I don;t want the time or expense of replacing the covering every few years.  I also don't want to deal with the possibility that I can't get a cover when it needs replacing.  The world doesn't look too stable at the moment.  And I'm planning for self-sustainability for 55+ years,  I want what I build to last.  

I plan on putting raised beds in the greenhouse, but I won't be putting in a slab.  I want the raised beds (about 2 feet high) in touch with the ground below.  I don't know if that would make it any easier.  The ground in the greenhouse needs to be level, so I'm concerned about water flow.
