Julia Grabowski

Julia's work is centered around applying programming and GIS techniques, including land cover classification, photogrammetry, and data wrangling, to solve complex problems in river management. She has classified both native floodplain forest and invasive aquatic vegetation cover large areas of the Willamette River floodplain in order to inform riverscape management. She has supported the U.S. Army Corps of Engineers by processing large-scale, high-resolution imagery data collected from crewed aircraft over the McKenzie and North Santiam Rivers. She leverages the capabilities of the National Hydrography Dataset (NHD) and the National Water Information System (NWIS) record to accomplish tasks like classifying the Willamette River Basin stream network by obstruction to fish passage, and compiling approximately 300,000 stream velocity measurements throughout the Pacific Northwest. She is proficient in R and Python.

Julia is also proficient in high-precision water sample collection and processing techniques. She works for the National Water-Quality Network (NWQN) to collect and process water-quality samples using parts-per-million techniques. She has collected approximately 40 eDNA samples throughout the Willamette River Basin.
