Improved Hydrologic Modeling for Characterizing Variable Contributing Areas and Threshold-Controlled Overland Flow in Depression-Dominated Areas
(North Dakota State University, 2020)
Surface depressions are important topographic features, which affect overland flow, infiltration, and other hydrologic processes. Specifically, depressions undergo filling-spilling-merging-splitting processes under natural ...
An Investigation of the Mechanical Properties of Swelling Clays and Clay-Kerogen Interactions in Oil Shale: A Molecular Modeling and Experimental Study
(North Dakota State University, 2020)
This work provides an insight into how the molecular interactions influence macroscale properties of two materials: swelling clay and oil shale. Swelling clays cause enormous damage to infrastructure: buildings, roads, and ...
Development of Improved Methods for Watershed-Scale Topographic Analysis and Hydrologic Modeling
(North Dakota State University, 2020)
Surface depressions are one of the significant topographic characteristics in depression-dominated areas and can retain runoff and break the hydrologic continuity in watersheds. In traditional semi-distributed models, the ...
Utilization of Granular Activated Carbon Media to Improve Biofiltration for the Purpose of Taste and Odor Removal
(North Dakota State University, 2020)
To determine the role biofiltration in organic removal and taste and odor compound removal within the Moorhead Water Treatment Plant, a comparative two-year pilot scale study was initiated to determine the feasibility of ...
Evaluating the Safety and Mobility of the Cumulative-Anticipative Car-Following Model for Connected Autonomous Vehicles
(North Dakota State University, 2020)
The advancements of vehicle automation are progressively improving resulting in safer driving environments in addition to more efficient mobility and fuel cost savings. However, autonomous and connected autonomous vehicles ...
Detection of Two-Dimensional Internal Cracks in Concrete Using Point Strain Sensors
(North Dakota State University, 2020)
Tensile cracking in the concrete can destroy the structural frame since it induces water penetration in structure and foundation. For instance, in concrete pavements, cracking increases the potential for pavement distress, ...
Cumulative-Anticipative Car-Following Model for Enhanced Safety in Autonomous Vehicles
(North Dakota State University, 2020)
As the rapid development of smart cities, autonomous vehicles are considered to be the future ground transportation measure which provides many benefits over traditional human-driving vehicles. However, there will be decades ...
