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.

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
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)
Turbulence is the most important unsolved problem of classical physics.
Richard Feynman
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
What is sure is that the satellite view of our world and its evolution is now a common reality
Olivier Theyskens
Big whorls have little whorls, which feed on their velocity, And little whorls have lesser whorls, and so on to viscosity.
Dr. Lewis Richardson in Weather Prediction by Numerical Processes, pg. 66, 1922
I’ve known rivers: I’ve known rivers ancient as the world and older than the flow of human blood in human veins. My soul has grown deep like the rivers.
Langston Hughes
We owe our lives to the sun… How is it, then, that we feel no gratitude?
Lewis Thomas, Earth Ethics (Summer 1990)
Water is the best of all things.
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
