Experimental Studies on Infiltration/Soil-Water Movement Processes and Green-AMPT Modeling
(North Dakota State University, 2011)
Experimental studies on infiltration/soil-water movement processes are vital to
better understanding movement of soil-water in the vadose zone. The objective of this
experimental research was to investigate infiltratio ...
Parametric Cost Estimating and Risk Analysis of Transportation Tunneling Projects
(North Dakota State University, 2016)
Due to the increased scrutiny of construction costs for infrastructure projects by the
public and legislators, it is becoming increasing important for project developers to prepare
accurate conceptual cost estimates for ...
A Stochastic Bayesian Update and Logistic Growth Mapping of Travel-Time Flow Relationship
(North Dakota State University, 2017)
The travel-time flow relationship is not always increasing in nature, it is very difficult to predict precisely. Traditional method fails to replicate this unique conditions. Until millennium, although various researchers ...
Comparitive Analysis of Turbidity and Organics Removal in Biological Activated Carbon and Anthracite-Sand Filters in the Moorhead Water Treatment Plant
(North Dakota State University, 2019)
The source water for the Moorhead Water Treatment Plant (MWTP) exhibits high concentrations of total organic carbon (TOC) throughout the year and seasonal taste and odor (T&O) events. To prevent biological regrowth in the ...
Spatial Scale Dependence of Drought Characteristics and Impact of Drought on Agriculture and Groundwater
(North Dakota State University, 2016)
Drought is a water related natural hazard. It is difficult to characterize drought because of its diffused nature and spatiotemporal variability. However, understanding the variability of drought characteristics such as ...
Development of Operational Strategies to Minimize Bromate Formation in the Moorhead Water Treatment Plant
(North Dakota State University, 2014)
A recent study at the Moorhead water treatment plant (MWTP) determined that bromate formed during ozone disinfection and, at times, exceeded the maximum contaminant level (MCL) of 10 parts per billion (ppb) in the summer ...
Alginate Encapsulated Nanoparticle-Microorganism System for Trichloroethylene Remediation
(North Dakota State University, 2012)
Nanoscale zero-valent iron (NZVI) particles were encapsulated in calcium alginate capsules for application in environmental remediation. TCE degradation rates for encapsulated and bare NZVI were similar indicating no adverse ...
Initial Swelling Mechanism of Expansive Clays: A Molecular Dynamics Study
(North Dakota State University, 2012)
Expansive soils are widely found in many parts of the world. Highly active smectite clay mineral Montmorillonite is the major constituent in these clays and can expand or contract up to 15 times of their original volume. ...
Identification of Delamination Defects in CFRP Materials through Lamb Wave Responses
(North Dakota State University, 2014)
Delamination is currently a largely undetectable form of damage in composite laminate materials. This thesis will develop a method to more easily detect delamination damage within composite materials. Using finite element ...
Calibrating Smartphones for Monitoring Road Condition on Paved and Unpaved Roads
(North Dakota State University, 2018)
Transportation agencies report the localization of roadway anomalies that could cause serious hazards to the traveling public. However, the high cost and limitations of present technical prevent scaling the road monitoring ...
