Advancing Streamflow Forecasts Through The Application Of A Physically Based Energy Balance Snowmelt Model With Data Assimilation And Cyberinfrastructure Resources, Tseganeh Zekiewos Gichamo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Colorado Basin River Forecast Center (CBRFC) provides forecasts of streamflow for purposes such as flood warning and water supply. Much of the water in these basins comes from spring snowmelt, and the forecasters at CBRFC currently employ a suite of models that include a temperature-index snowmelt model. While the temperature-index snowmelt model works well for weather and land cover conditions that do not deviate from those historically observed, the changing climate and alterations in land use necessitate the use of models that do not depend on calibrations based on past data. This dissertation reports work done to overcome these …

The Impact Of Wood Biochar On The Plant Uptake Of Pharmaceuticals And Personal Care Products From Reclaimed Wastewater, Jeffrey Flashinski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reclaimed water (treated water discharged from wastewater treatment plants (WWTPs)) is increasingly used in drier regions for irrigation purposes. This effectively increases the water supply and reduces the amount of WWTP discharge into surface waters but it creates the potential for contaminants in the reclaimed water, such as pharmaceuticals and personal care products (PPCPs), to accumulate in exposed crops. The US Environmental Protection Agency (US EPA) considers PPCPs contaminants of emerging concern due to their near universal presence in the environment and their potential for endocrine disruption. Biochar is gaining attention as a soil amendment and could potentially be used …

Calcium Sulfoaluminate Cement Concrete For Prestressed Bridge Girders: Prestressing Losses, Bond, And Strength Behavior, Nicholas Markosian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Calcium sulfoaluminate (CSA) cement was used to cast a prestressed voided deck slab bridge girder. The rapid-set properties of CSA cement allowed the initial concrete strength to reach the required 4300 psi needed in order to cut the prestressing strands 6.5 hours after casting. Prestress losses were monitored long-term using vibrating wire strain gages cast into the concrete at the level of the prestressing strands and the data was compared to the American Association of State Highway and Transportation Officials Load and Resistance Factor Design (AASHTO LRFD) predictions for prestress losses. AASHTO methods for prestress loss calculation were overestimated compared …

Hydraulic Average Of Multiple Tap Sets To Improve Performance Of Venturi Flowmeters With Upstream Disturbance, Taylor Stauffer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Venturi flowmeters have been used to measure flow in piped systems for over 100 years (Finnemore & Franzini, 2006). There has been much research on the performance of Venturi flowmeters and for that reason they have become popular flowmeters used in various municipal and industrial applications. Venturi flowmeters can be calibrated in a laboratory setting to find their performance characteristics. In order for the flowmeter to achieve optimum performance, the flowmeter should be installed with sufficient length of straight pipe immediately upstream of the flowmeter. Often Venturi flowmeters that are not installed in ideal conditions produce errors and uncertainty is …

Estimating Upper Red Butte Watershed Contribution To Salt Lake Valley Water Resources, Sal Bir Limbu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water is crucial for domestic, agricultural, industrial, environmental, and hydropower uses. Once precipitation occurs, it eventually partitions into streamflow, evapotranspiration (ET), and groundwater recharge. Distribution of precipitation into these partitions is called a hydrologic budget. The hydrologic budget of any geographic area or watershed under different climate change conditions help water managers to make appropriate water management plans. Computer based hydrologic modeling software has been used extensively to solve many water resources problems including hydrologic budgets. Hydrologic modeling requires high quality weather parameter data.

This study projected surface and groundwater flows from the portion of RBC watershed that lies above …

Lateral And Torsional Seismic Vibration Control For Torsionally Irregular Buildings, Osman Akyürek

Theses and Dissertations

During strong earthquakes or wind gusts, it is likely that buildings with torsional irregularity in the plan have an can be seriously damaged, partially collapsed or fully collapsed. This is because Torsionally Irregular Buildings (TIBs) may have significant aerodynamic torsion loads that increase the eccentricity between the center of mass and the center of rigidity, especially in dominant torsion modes. For this reason, torsion leads to excessive increase in lateral motions when dynamic loads excite the buildings. Torsional irregularity is one of the main failure causes during strong dynamic excitations due to earthquakes or wind gusts. Ignoring torsional irregularity in …

Damping Coefficient Sensitivity Analysis Of High Rebound Soils In Florida, Aline Franqui

Theses and Dissertations

The dynamic response of soils is related to a damping factor, which represents the energy absorbed by the soil as the pile moves. Certain blends of fine sands, silts and clays are producing pile rebound during driving. For that reason, the objective of this thesis is to conduct a damping coefficient sensitivity analysis of high rebound soils in Florida. Forty cyclic triaxial tests from six sites in Central and Northern Florida were analyzed to evaluate damping. Two approaches were used, one based on the change in stress over time and a second based on the viscous energy absorbed per cycle. …

Effect Of Industry Clusters And Commodity Flow Characteristics On The Selection Of Freight Transportation Modes In The United States With Advanced Econometric Approaches, Taleb Eissa Ali Eissa

Theses and Dissertations

Mode choice is an important strategic decision for shippers to carry commodities efficiently. Freight mode-choice is an important activity to develop a successful freight transportation business in the private sector and to plan for economically consistent freight transportation infrastructures in the public sector. Freight activities result from the complex interactions between different economic agents, but these relationships are commonly relaxed to account for three major agents: shippers, carriers and receivers. Furthermore, the behavior of freight choice is commonly not concentrated in one agent, but rather is divided jointly over multiple individuals and firms in a logistics process, each component of …

Design And Analysis Of Fiber Reinforced Concrete Structure For Transportation Infrastructures, Salam Adil Mutlag Wtaife

Theses and Dissertations

Concrete is one of the most popular materials in superstructures (buildings), substructures (foundation) and infrastructure facilities (bridges, pavements, and tunnels). However, concrete is a brittle material that cracks easily under tension. Fiber may be used as reinforcement to impede the concrete from cracking as well as to increase the concrete flexural strength. Nevertheless, current design codes do not include this design enhancement. Furthermore, there are discrepancies in the design methodology concerning the inclusion of discrete fibers in concrete structures. Therefore; there is a need to develop new analysis methodology and design methodology for fiber reinforced concrete (FRC) and fiber reinforced …

Modeling Of Hurricane-Induced Interior And Contents Damage And Associated Time-Related Expenses To Residential Buildings, Roberto Vicente Silva De Abreu

Theses and Dissertations

Hurricanes are a main cause of economic losses in many parts of the world, including the state of Florida. They affect the exterior, interior, and the contents of residential buildings. The damage of the interior can be as much as half of the total damage, but the estimation of the interior damage is still somewhat crude. Most damage models estimate interior damage as a percentage of the exterior damage, or through simple relationships, that relate the height of water ingress in the building to the interior damage. The current version of the Commercial Low-Rise Residential vulnerability model (CLR) of the …

Airport Taxiway Traversal And Safety Optimization Using Combinatorics, Thore Groenlund Rasmussen

Theses and Dissertations

The demand for air travel has increased dramatically in the last decade, putting large strain on airports and their limited resources. Expanding the available resources at an airport is not always an option either due to location, budget or time. This forces the administrators of an airport system to use the limited resources as efficiently as possible. This thesis proposes a tool for air traffic controllers and pilots that can be used when planning taxiway systems. Taking inspiration from Dijkstra’s Algorithm, an algorithm is proposed to safely move aircraft from the terminal to the runway. Applying constraints to the algorithm …

Driving Performances Assessment Based On Speed Variation Using Dedicated Route Truck Gps Data, Ying Li, Li Zhao, Laurence R. Rilett

Department of Civil and Environmental Engineering: Faculty Publications

It was hypothesized that a driver is not safe when travel speed is too high and also not necessarily safe when travel speed is too low. Based on this hypothesis, this paper studied the risky driving performances by measuring speed variations of a driver’s recurrent trips in two perspectives: 1) driver profiles, which scored the risk on-road driving of each driver and 2) driving patterns, which reflected the risk speed patterns of a type of drivers. The proposed method was tested on a 30-day global positioning system (GPS) dataset, collected from 100 trucks. The study first split the raw dataset …

Civil Engineering Faculty Publications

This study reports the preliminary results from a statistical screening of tree-ring width records from the International Tree-Ring Data Bank (ITRDB), to evaluate the strength of the hydrological signal, in dendrochronological records from the Tennessee Valley. We used United States Geological Survey (USGS) streamflow data from 11 gages, within the Tennessee Valley, and regional tree-ring chronologies, to analyze the dendroclimatic potential of the region, and create seasonal flow reconstructions. Prescreening methods included correlation, date, and temporal stability analysis of predictors to ensure practical and reliable reconstructions. Seasonal correlation analysis revealed that large numbers of regional tree-ring chronologies were significantly correlated …

Equilibrium-Based Workload Balancing For Robust Emergency Response Operations In Metropolitan Areas, Parya Roustaee

Civil and Environmental Engineering Theses and Dissertations

This thesis presents an equilibrium-based modeling framework for emergency response (ER) workload balancing to achieve robust operation in large-scale metropolitan areas. The problem is formulated as a non-linear mathematical program (NLP), which determines the optimal workload cutoff for each ER station such that the weighted sum of the area-wide expected response time and its variation are minimized. The concept of Marginal Cost of Uncertainty (MCU) is introduced to measure the impact of a station’s workload increase on the area-wide service performance. The solution of the NLP is proved to be equivalent to a state of equilibrium in which all stations …

Seismic Performance Of Earth Slopes Subjected To Earthquake Mainshock – Aftershock Sequences, Alisha Khanal

Civil Engineering Theses

Mainshocks are usually followed by aftershocks. Aftershocks continue over a period of time with a decreasing frequency and there is not sufficient time for repair and retrofit between a mainshock – aftershock sequence. Typically, aftershocks are smaller in magnitude; however, aftershock ground motion characteristics such as the intensity and duration can be greater than the mainshock due to the changes in the earthquake mechanism and location with respect to the site. The seismic performance of slopes is typically evaluated based on the sliding displacement predicted to occur along a critical sliding surface. Various empirical models are available that predict sliding …
