Three students of engineering, water management and environmental science are winners in a new international competition for proposals to advance sustainability in coastal cities.

The competition targeted upcoming water-resources professionals and was part of the run-up to an “H209” symposium to be held Sept. 9-10 at Liberty Science Center in Jersey City, N.J. The event is a forum for water-management professionals and coincides with joint Dutch and New York celebrations of the 400th anniversary of the explorer Henry Hudson’s landfall in New York.
