RSS 1.0Department 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.
