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.

Applications of Activated Carbon to Reduce Disinfection Byproducts in Small Drinking Water Systems
(University of Missouri--Columbia, 2015)The addition of chlorine disinfectant to drinking water during the treatment process results in the formation of disinfection by-products (DBPs). The United States and several other nations regulate for DBPs in drinking ... -
Experimental and Analytical Evaluation of Disproportionate Collapse Flat-Plate Buildings
(University of Missouri--Columbia, 2015)Reinforced concrete flat plate buildings without continuous integrity reinforcement may be vulnerable to disproportionate collapse if a supporting structural member was lost in an abnormal event. This research forces on ... -
Reduction of DBP Formation Potential in Drinking Water through Forced Alkaline Conditions and Aeration
(University of Missouri--Columbia, 2015)As the United States Environmental Protection Agency (USEPA) moves to the more stringent Disinfection By Product (DBP) Stage 2 rule, small communities are challenged to meet the regulations. According to compliance data ... -
Verification of Thermographic Bridge Inspection Technologies
(University of Missouri--Columbia, 2015)This paper covers the research performed to determine the reliability of infrared technology as an inspection tool for concrete bridge components. Concrete deteriorates due to the corrosion of embedded reinforcing steel. ... -
Dynamic Capacity of Isolated Slab Column Specimens
(University of Missouri--Columbia, 2015)Localized damage, particularly in flat plate structures, can cause a chain reaction of subsequent failures resulting in failure of a large portion or even the entire structure. This type of failure is known as a progressive ... -
Application of advanced adsorption processes for dissolved organic matter and heavy metal removal from water sources
(University of Missouri--Columbia, 2015)The main objective of this research was to develop an improved understanding of natural organic matter (NOM) and heavy metals removal from two water sources: the City of Columbia McBaine Water Treatment Plant and synthetic ... -
Change in sludge settling and filtration properties and membrane fouling trends in MBR activated sludge systems operated at different solids and hydraulic retention times
(University of Missouri--Columbia, 2014)Membrane bioreactor (MBR) activated sludge process is increasingly used in wastewater treatment due to its excellence in solid-liquid separation and superior effluent quality, smaller bioreactor volume and foot print. ... -
Evaluating the variables that impact ultrasonic testing
(University of Missouri--Columbia, 2014)The goal of this research was to improve the quality control process for steel fabrication to improve the reliability, safety and quality of welded steel components. The objectives of this project were to explore the ... -
Dry weight and cell density of individual algal and cyanobacterial cells for algae research and development
(University of Missouri--Columbia, 2014)Phototrophs have received more and more attention due to their nutrient removal, biomass production as well as the potential for biofuel feedstock. This research determined the dry weight of algal and cyanobacterial cells ... -
Emissions of greenhouse gases carbon dioxide and methane from duckweed systems for stormwater treatment
(University of Missouri--Columbia, 2014)This study determined the greenhouse gas emission from lab-scale duckweed treatment systems that were used for stormwater treatment. By using the static chamber technique, the fluxes of CO2 emission from the duplicate ... -
Engineering-based analysis of pre-development hydrology stormwater policy for transportation applications
(University of Missouri--Columbia, 2014)Ongoing concern over water quality impacts from development has prompted consideration of a return to pre-development hydrology as a possible solution strategy. The Environmental Protection Agency (EPA) has equated ... -
Comparison of nondestructive testing technologies used for inspection of welded joints
(University of Missouri--Columbia, 2014)The purpose of this research is to report on the comparison between different nondestructive test (NDT) methods applied for the detection of defects in welds. NDT methods such as Ultrasonic Testing (UT), Magnetic Particle ... -
