Key Concepts
The hydrologic cycle describes the continuous movement of water on, above, and below the surface on the earth. This flow is altered by ecosystems at numerous points. Transpiration from plants provides the majority of flow of water to the atmosphere. Water is influenced by vegetative cover as it flows over the land surface, while river channels can be shaped by the vegetation within them.
Ecohydrologists study both terrestrial and aquatic systems. In terrestrial ecosystems (such as forests, deserts, and savannas), the interactions among vegetation, the land surface, the vadose zone, and the groundwater are the main focus. In aquatic ecosystems (such as rivers, streams, lakes, and wetlands), emphasis is placed on how water chemistry, geomorphology, and hydrology affect their structure and function.

Famous quotes containing the words key and/or concepts:
“This is not a book. This is libel, slander, defamation of character. This is not a book, in the ordinary sense of the word. No, this is a prolonged insult, a gob of spit in the face of Art, a kick in the pants to God, Man, Destiny, Time, Love, Beauty ... what you will. I am going to sing for you, a little off key perhaps, but I will sing.”
—Henry Miller (1891–1980)
“When you have broken the reality into concepts you never can reconstruct it in its wholeness.”
—William James (1842–1910)
