The goal of my research program is to understand the physical processes that control the movement of water and sediment and the effects that the variability of these processes have on water availability, water quality, and stream ecology. I recognize that we are not yet able to predict the natural variability of runoff processes nor their influence on the flux of water, solutes, and sediment in the landscape. This constitutes a barrier for society to successfully adapt to natural and anthropogenic disturbances such as climate change. Our lack of understanding of the physics that controls the movement of water through catchments is particularly challenging in mountainous-forested headwater streams. In these streams, water and sediment inputs and hydrologic response vary over short distances given variable geology, geomorphology, and topography. Oregon’s diverse geology and topography provide an ideal natural laboratory to investigate the controlling effect of the natural setting (climate and geology) on runoff generation and sediment transport. In addition, the State supports forested ecosystems economically relevant to the region for timber production and for the sustainability of terrestrial and aquatic ecosystems health and productivity.
Native of Bogotá, Colombia, where she received her BS in Forestry Engineering (1997). She later worked in the private sector in environmental consulting for 3 years. She completed her MS. in Environmental Engineering at the University of Washington (2003) and her PhD in Physical Geography at the University of Colorado (2008). Dr. Segura was a Postdoctoral Fellow at NCSU for the Forestry Department (2008-2010) and then for the Marine, Earth, and Atmospheric Sciences department (2012-2013). She joined the Department of Forest Engineering, Resources, and Management at OSU in December 2013.
