Identification Of Phosphorous Loading Point Source Facilities To 303(D) Listed Nutrient Impaired Waters Through Watershed Delineation Using Arcgis For Life Cycle Assessment Applications, John Zimmerman

Chemical Engineering Undergraduate Honors Theses

The work done for this project is part of a larger “life cycle assessment (LCA) of novel electrochemical phosphorus recovery technology at the wastewater treatment plant and U.S. watershed scales” (Morrissey 2019). The goal of that LCA is to determine “environmental impacts of implementing electrochemical struvite recovery at the wastewater treatment plant, U.S watershed, and global scales” (Morrissey 2019). This project’s goal is to identify locations deemed more sensitive to eutrophication impacts. The results will be used as part of the life cycle inventory (LCI) accounting for geographically explicit phosphorus flows. The waters identified as impaired were sourced from the …

An Exploration Of Lean And Bim Synergies With A Focus On Smes In Construction, Barry Mcauley, Marina Andreou, Alan V. Hore, Avril Behan

Conference papers

Small and Medium Enterprises (SME) account for 99.7% of the Irish Construction Industry and contribute to 68% of all employment in the sector. These organisations now find themselves facing the challenge of returning to productive business post the Covid 19 shutdown. More than ever, SMEs must modernise and adapt their business models to embrace new ways of working, such as Lean Construction and Building Information Modelling (BIM), in the absence of clear business incentives. It has proved difficult to persuade SMEs to change their ways of working due to limited finances, internal resources and above all, the cultural shift required …

Develop A Multi-Functional Green Pervious Concrete (Mgpc) Pavement With Polycyclic Aromatic Hydrocarbons (Pahs) Removal Function., Hong Shang

Electronic Theses and Dissertations

Stormwater runoff induced Polycyclic Aromatic Hydrocarbons (PAHs) contaminant increasingly imperils the groundwater quality and the sustainable development of human society due to the potential carcinogenic risks. Pavement can be considered as the first line of defense for contaminant removal of the stormwater runoff. New construction materials with stormwater runoff quantity and quality control are in urgent demand for updating the existing pavement system. An innovative material called Multi-functional Green Pervious Concrete (MGPC) was developed in the department of Civil and Environmental Engineering at University of Louisville. This material uses organoclay as the amendment to enhance the PAHs removal capacity of …

Analysis Of Shear-Strength In Weathered Shale Strata Along A Highway Slope Failure Site In Northwest Arkansas, Olivia Overton

Civil Engineering Undergraduate Honors Theses

Slope failures cost millions of dollars per year to repair and can be deadly. Accurate modeling of slope conditions, including soil parameters, water table locations, and depth to bedrock, are essential to determining the overall stability of a slope. This project is a continuation of the work completed in 2019 by a former University of Arkansas researcher, Vanessa LeBow. LeBow RocScience used Slide2 modeling software to model two highway embankment slopes in Northwest Arkansas that experienced slope movement to determine whether increased use of geophysical data could increase the accuracy of slope stability models. A parametric study of shear strengths …

Breaking Wave Hazard Estimation Model For The U.S. Atlantic Coast, Spencer T. Hallowell

Publications

As offshore wind development is in its infancy along the U.S. Atlantic Coast challenges arise due to the effects of strong storms such as hurricanes. Breaking waves on offshore structures induced by hurricanes are of particular concern to offshore structures due to high magnitude impulse loads caused by wave slamming. Prediction of breaking wave hazards is important in offshore design for load cases using long mean return periods of environmental conditions. A breaking wave hazard estimation model (BWHEM) is introduced that provides a means for assessing breaking hazard at long mean return periods over a large domain along the U.S. …

Potencial De Mallas Tejidas En Fibras Del Pseudotallo De La Planta De Plátano Musa X Paradisiaca Para La Protección Del Suelo Y El Control De Erosión En Taludes, Alma Linda Villadiego Durango, Brenda Alejandra Sandoval Carrillo

Ingeniería Civil

El proyecto plantea la elaboración de biomallas temporales hechas a partir de la fibra natural del pseudotallo de la planta de plátano (Musa x paradisiaca), las cuales fueron sometidas a diversas pruebas para comprobar su eficacia en la protección de taludes y reducción de la erosión laminar en los suelos, ya que esta última puede afectar la productividad del suelo, generar deslizamientos, inundaciones, dañar la infraestructura urbana e incluso generar desplazamientos de la población. Para resolver lo anteriormente planteado se llevaron a cabo pruebas en campo durante 2 meses, en un talud natural protegido con la biomalla y otro sin …

Erosion And Sediment Controls On Reclaimed Mine Refuse Impoundments, Sara Dalen

Graduate Theses, Dissertations, and Problem Reports

To ensure the sustainable use of one of West Virginia’s precious resources, conscientious long-term management of residual waste is of immense importance. This thesis examined two main topics: i) the dewatering process of acid mine drainage (AMD) sludge, and ii) an investigation of soil loss predictions of a reclaimed coal refuse impoundment.

The first aspect of this thesis addresses clarification and remediation of AMD prior to disposal is a prominent component to preventing runoff and seepage of environmentally detrimental byproducts. To examine the effects of flocculation and dewatering more closely by means of geotextiles, an AMD sludge was analyzed. The …
