To treat the Uintah svn tree as a git repository, you can use git-svn. It is recommended that you clone from a specific revision to avoid a long wait of cloning the entire uintah svn tree. I always clone from the HEAD revision.
git svn clone -r HEAD https://gforge.sci.utah.edu/svn/uintah/trunk/ uintah-work
Now treat uintah-work as a regular git repository.
Once you are ready to push changes back to the svn repository, use:
git svn dcommit
