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.

Three things cannot be long hidden: the sun, the moon, and the truth.
For life and death are one, even as the river and the sea are one.
Khalil Gibran, The Prophet
You can’t cross the sea merely by standing and staring at the water.
Rabindranath Tagore
The day, water, sun, moon, night – I do not have to purchase these things with money.
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 do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
Sir Isaac Newton. Memoirs of the Life, Writings, and Discoveries of Sir Isaac Newton, 1855 by Sir David Brewster
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
… Ocian in view! O! the joy! …
Captain William Clark upon seeing the Columbia River estuary, Nov. 7, 1805
The use of sea and air is common to all; neither can a title to the ocean belong to any people or private persons, forasmuch as neither nature nor public use and custom permit any possession therof.
Queen Elizabeth the I of England, Letters
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)
