Information

Dr. Antonio Arenas serves as an assistant professor at Iowa State University (ISU) in the Department of Civil, Construction, and Environmental Engineering. He has participated in a variety of research projects with an emphasis on the application and development of computational models and data analyses to understand and simulate surface-subsurface hydrologic interactions, the long-term effects of land-use changes on watershed hydrology and water quality, fish migratory behavior, spillway hydrodynamics, and total dissolved gas and temperature dynamics at hydropower reservoirs and tailraces. His current research focuses on developing and using fully coupled surface-subsurface watershed models to evaluate flood mitigation strategies and study the fate and transport of nutrients. Before joining ISU, Dr. Arenas worked as an associate research engineer at IIHR Hydroscience & Engineering at the University of Iowa (UI). He has a Ph.D. from UI, received a master’s degree from Universität Stuttgart (University of Stuttgart), and holds a bachelor’s degree from La Escuela Colombiana de Ingenieria. Research Interests

• Hydrology and hydraulics
• Computational modeling
• Climate change adaptation
• Nutrient fate and transport
• Spatial analysis for water resources management
