Effectiveness Of Water Quality Benefits Provided By Stormwater Management Facilities/Infiltration Basin, Vinicius Rodrigues De Mattos Barreto

Theses

Stormwater Best Management Practices (BMP) and devices are systems frequently built under assumed design performances, but rarely verified after construction. Their effectiveness in protecting the environment against pollutants carried by stormwater runoff has been extensively questioned and investigated. This research presents a case study of an infiltration basin in Medford, NJ to verify if the 80% expected Total Suspended Solids (TSS) removal as stated in the New Jersey Stormwater BMP Manual is actually achieved. A sampling pit was installed on the site and infiltrated water samples were collected during three rain events and TSS measurements were compared with the inflow. …

Multi-Regression Prediction Of Metal Partition Coefficients Under Various Physical/Chemical Conditions Design Of Experiments As, Cr, Cu, Ni And Zn, Eid A. Alkhatib, Danielle Grunzke, Trey Chabot

Chemistry & Physics Faculty Publications

The behavior of metals in surface water is complex and their partition coefficients can be impacted by many factors. Organic matter (OM) content in sediments, pH and salinity, are factors that may influence speciation and partitioning of metals. The difficulty in describing the impacts and relationships are that these processes are interconnected with no dominant associations among all. In this study, the partitioning of five metals (As, Cr, Cu, Ni and Zn) under different levels of salinity, pH, and OM content were investigated. A series of factorial design experiments are evaluated in which three levels of OM are tested each …

Developing The Greatest Blue Economy: Water Productivity, Fresh Water Depletion, And Virtual Water Trade In The Great Lakes Basin, A. L. Mayer, Stanley Mubako, Benjamin L. Ruddell

Michigan Tech Publications, Part 1

The Great Lakes basin hosts the world's most abundant surface fresh water reserve. Historically an industrial and natural resource powerhouse, the region has suffered economic stagnation in recent decades. Meanwhile, growing water resource scarcity around the world is creating pressure on water-intensive human activities. This situation creates the potential for the Great Lakes region to sustainably utilize its relative water wealth for economic benefit. We combine economic production and trade datasets with water consumption data and models of surface water depletion in the region. We find that, on average, the current economy does not create significant impacts on surface waters, …

A Contingency Cost Estimation System For Road Maintenance Contracts, Kishor Shrestha, Pramen Shrestha

Civil and Environmental Engineering and Construction Faculty Research

Generally, a contingency cost is provided in a project to cover the change orders (CO) that may be generated in a project during the construction phase due to various reasons, such as unforeseen conditions, design errors, and scope changes. If the contingency cost could be accurately estimated during the contract's procurement phase, the CO cost could be properly managed during the construction phase. Traditionally, contingency costs are allocated around 10% to 15% of the project cost without considering any of the historical CO costs. In this study, a tool was developed to estimate the contingency cost of a road maintenance …

One of the most significant solutions to sustain the fatigue life for an asphaltic mixture is to add sustainable materials such as rubber or polymers to the asphalt mixture. A laboratory testing program was performed on three gap-graded mixtures: unmodified, Asphalt Rubber (AR) and polymer-modified. Strain controlled fatigue tests were conducted according to the AASHTO T321 procedure. The results from the …

Potential For Biofuel Production From Algae Based Wastewater Treatment In California: Can Algal Biofuels Be Cost-Competitive With Traditional Petroleum Based Diesel?, Amanda Rupiper

Master's Projects and Capstones

Neither the use of algae to clean wastewater, nor the use of photosynthetic organisms to generate biodiesel, are new concepts on their own. By combining these two processes, algal-based wastewater treatment with algal biofuel production, additional benefits can be derived, among which could be a cost-savings. In California the average estimated base production cost per gallon for algal biodiesel is $5.98/gallon. Compared to the adjusted production cost of petroleum-based diesel of $1.53/gallon, biodiesel is not cost-competitive. Coupling wastewater treatment and algal cultivation reduces the net energy use of the two processes separately and, if accounted for, greatly reduces the production …

Determination Of Specific Heat Capacity On Composite Shape-Stabilized Phase Change Materials And Asphalt Mixtures By Heat Exchange System, Biao Ma, Xue-Yan Zhou, Jiang Liu, Zhanping You, Kun Wei, Xiao-Feng Huang

Michigan Tech Publications, Part 1

Previous research has shown that composite shape-stabilized phase change material (CPCM) has a remarkable capacity for thermal storage and stabilization, and it can be directly applied to highway construction without leakage. However, recent studies on temperature changing behaviors of CPCM and asphalt mixture cannot intuitively reflect the thermoregulation mechanism and efficiency of CPCM on asphalt mixture. The objective of this paper is to determine the specific heat capacity of CPCM and asphalt mixtures mixed with CPCM using the heat exchange system and the data acquisition system. Studies have shown that the temperature-rise curve of 5 °C CPCM has an obvious …

Tidal River Dynamics: Implications For Deltas, Ton Hoitink, David A. Jay

Civil and Environmental Engineering Faculty Publications and Presentations

Tidal rivers are a vital and little studied nexus between physical oceanography and hydrology. It is only in the last few decades that substantial research efforts have been focused on the interactions of river discharge with tidal waves and storm surges into regions beyond the limit of salinity intrusion, a realm that can extend inland hundreds of kilometers. One key phenomenon resulting from this interaction is the emergence of large fortnightly tides, which are forced long waves with amplitudes that may increase beyond the point where astronomical tides have become extinct. These can be larger than the linear tide itself …

This system incorporates four evenly spaced cables, Midwest Weak Posts spaced at 8 to 16 ft (2.4 to 4.9 m) intervals, and a bolted, tabbed bracket to attach the cables to each post. Full-scale crash testing was needed to evaluate the barrier’s safety performance. According to the Manual for Assessing Safety Hardware (MASH) updated/proposed testing matrix for cable barriers installed within a 6H:1V or median ditch, a series of eight full-scale tests are required to evaluate the safety performance of a system. A ninth test is …

Approximation Assessment Of Photocatalytic Air Cleaning Pavements, James E. Alleman, Joel K. Sikkema, Peter C. Taylor

Faculty Work Comprehensive List

This paper examines an approximation method to qualitatively assess the air-cleaning performance (i.e., specifically the elimination of aerial nitrogen oxide, NO, released within vehicular exhaust) by full-scale pavements which contain photo-catalytically reactive titanium dioxide under optimal conditions. Two hypothetical road configurations were considered using this method, including both a two-lane, low traffic density (i.e., 4,000 full-day AADT) and a four-lane, moderate traffic density (i.e., 10,000 full-day AADT) design. These options were then comparatively examined on the basis of expected European Union or United States vehicular emission levels. In each case, this method’s day-time-only percentile elimination approximation results were derived using …

These characteristics make lithium-ion batteries advantageous for many new and developing applications that require large scale energy storage such as electric vehicles and the utility grid. Typical uses for lithium-ion batteries require consistent cycling patterns that are predictable and easy to approximate across all uses, but new large scale applications will have much more dynamic demands. The cycling patterns for …

Incorporating Vehicle Mix In Stimulus-Response Car-Following Models, S Siuhi, Mohamed Kaseko

Civil and Environmental Engineering and Construction Faculty Research

The objective of this paper is to incorporate vehicle mix in stimulus-response car-following models. Separate models were estimated for acceleration and deceleration responses to account for vehicle mix via both movement state and vehicle type. For each model, three sub-models were developed for different pairs of following vehicles including “automobile following automobile,” “automobile following truck,” and “truck following automobile.” The estimated model parameters were then validated against other data from a similar region and roadway. The results indicated that drivers' behaviors were significantly different among the different pairs of following vehicles. Also the magnitude of the estimated parameters depends on …

Volatile Organic Compound (Voc) Emission During Cured-In-Place-Pipe (Cipp) Sewer Pipe Rehabilitation, Elena Bourbour Ajdari

LSU New Orleans Theses and Dissertations

The maintenance or replacement of deteriorated pipes and culverts is a constant and significant concern for municipalities and transportation agencies in the United States (Donaldson and Wallingford, 2010). Trenchless technologies and especially the Cured-in-place pipe (CIPP) method have become increasingly common ways to preserve infrastructures owing to their feasibility, cost-effectiveness, and fewer social impacts (Jung and Sinha, 2007). Therefore, there is a growing need to understand the direct and indirect effects of pipeline rehabilitation activities on the environment. Nearly all past CIPP studies have focused on its mechanical properties, and its environmental impacts are poorly investigated and documented (Allouche et …
