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.
