Department of Civil and Environmental Engineering (MU)
Civil engineering, considered one of the oldest engineering disciplines, encompasses many specialties. The major ones are structural, water resources, construction, environmental, transportation, and geotechnical engineering. Environmental engineers develop solutions to environmental problems using the principles of biology and chemistry. Many environmental engineers work as consultants, helping their clients to comply with regulations, to prevent environmental damage, and to clean up hazardous sites.

Leveraging AI to assess inequities in pavement maintenance and rehabilitation strategies
(University of Missouri--Columbia, 2022)Pavement maintenance and repair (M&R) is an important social need that should be accessible to all regardless of social or economic circumstances. In this project, pavement condition is analyzed through the use of machine ... -
Investigation of transportation innovations for food delivery and truck platoons
(University of Missouri--Columbia, 2022)Studies find that low-income areas are underserved by food retailers and have less access to healthy food, contributing to health disparities. A section of this thesis examines micromobility, drones, and ridesharing that ... -
Waste plastic storage stability impact toward asphalt binder and mix performances
(University of Missouri--Columbia, 2022)The reutilization of waste plastic in asphalt binders and mixtures has become a popular field of research as the global scientific community looks to find avenues for the effective and efficient recycling of waste plastic. ... -
Interactive, multi-purpose traffic prediction platform using connected vehicles dataset
(University of Missouri--Columbia, 2022)Traffic congestion is a perennial issue because of the increasing traffic demand yet limited budget for maintaining current transportation infrastructure; let alone expanding them. Many congestion management techniques ... -
