Welcome to the website of the Fluvial, Oceanic, and Water-level Sciences (FLOWS) research group of the Department of Civil and Environmental Engineering at Portland State University. The unifying theme of our work is the influence of hydrodynamic processes on ecosystems. Though we specialize in physical oceanography, we study topics ranging from juvenile salmon to climate change, and wavelet transforms to beach ripples.

We can see cities during the day and at night, and we can watch rivers dump sediment into the ocean, and see hurricanes form.
Sally Ride in an interview with Scholastic, 1998
The winds, the sea, and the moving tides are what they are. If there is wonder and beauty and majesty in them, science will discover these qualities… If there is poetry in my book about the sea, it is not because I deliberately put it there, but because no one could write truthfully about the sea and leave out the poetry.
Rachel Carson at an acceptance speech of the National Book Award for Nonfiction, 1952
Rivers, ponds, lakes and streams – they all have different names, but they all contain water. Just as religions do – they all contain truths.
Muhammed Ali
I am an old man now, and when I die and go to heaven there are two matters on which I hope for enlightenment. One is quantum electrodynamics, and the other is the turbulent motion of fluids. And about the former I am rather optimistic.
Horace Lamb in Turbulence: an Introduction, 1932
Turbulence is the most important unsolved problem of classical physics.
Richard Feynman
Whenever I gaze up at the moon, I feel like I’m on a time machine. I am back to that precious pinpoint of time, standing on the foreboding yet beautiful – Sea of Tranquility. I could see our shining blue planet Earth poised in the darkness of space.
Buzz Aldrin, in an article for National Geographic News (May 12, 2013)
On your arrival on that coast, endeavor to learn if there be any port within your reach frequented by the sea-vessels of any nation, and to send two of your trusty people back by sea, in such way as shall appear practicable, with a copy of your notes.
President Thomas Jefferson
No man ever steps in the same river twice, for it’s not the same river and he’s not the same man.
Cryin’ won’t help you, prayin’ won’t do you no good, Now, cryin’ won’t help you, praying won’t do you no good, When the levee breaks, mama, you got to move
Led Zeppelin. "When the Levee Breaks". Led Zeppelin IV. 1971
The care of rivers is not a question of rivers, but of the human heart.
Tanaka Shozo, 1910
