    There are some common elements between the three, but they are hugely different. So different they probably aren’t handled by the same set of government agencies.

    The important thing is not to get overwhelmed! Just skim a bit and get an idea of what’s going on:

    This Wikipedia article considers the impact of reservoirs and dams: http://en.wikipedia.org/wiki/Environmental_impacts_of_dams

    This article about ports shows how very different the concerns are: http://www.ukmarinesac.org.uk/activities/ports/ph3_2.htm

    This one, for something different, considers the impact of fixing a broken bridge: http://environment.fhwa.dot.gov/projdev/bridge_casestudy.asp
