Air-Water Interface Flows in Pipe Emptying

Dlamini, Malusi (2020-07-15)

Pipe emptying is an important component of water supply operations. Pipes can be drained as a scheduled operation preceding maintenance, flushed for health reasons or they may empty as a result of an accidental break causing ...

Cellular Confinement as a Means to Limit Sediment Resuspension

Simpson, Timothy (2017-07-22)

This document contains the findings of experimental research that examines the effectiveness of small-scale confinement cells within the context of sediment basins, channels, or ditches. The confinement cells were tested ...

Characterization of unsteady multiphase flows in stormwater management applications

Wang, Jue (2018-08-20)

Intense rain events create many issues in urban areas, including flooding, overflows in stormwater systems, sediment pollution, etc. In many circumstances, flows are unsteady and characterized by multiphase flow conditions, ...

Comparison of Vegetation Types for Prevention of Erosion and Shallow Slope Failure Along Roadways

Asima, Homayra (2022-08-03)

Shallow slope failures due to erosion are common occurrences along roadways in Alabama due to the prevalence of high intensity rainfall in the region. The use of vegetative covers is a reasonable solution to stabilize newly ...

Design and Construction of a Rainfall Simulator for Large-Scale Testing of Erosion Control Practices and Products

Horne, Matthew (2017-04-14)

Soil erosion and the resulting sediment deposition constitutes one of the greatest pollutants in our nation’s waterways. Construction projects often generate large areas of exposed soil that remain disturbed throughout the ...

Design Guidance and Development of Construction Stormwater Technologies

Liu, Lan (2020-10-19)

As one of the largest sources of nonpoint source pollution, soil erosion has become an increasingly important topic in the U.S. Construction sites. Erosion and sediment control (ESC) practices are commonly used on ...

Developing a Practical Tool for Integrating Green Infrastructure into Cost-Effective Stormwater Management Plans

Ellis, Jackson (2020-07-14)

Urban stormwater management today aims to manage both the quantity and quality of stormwater runoff. Best management practices (BMPs) such as detention basins have long been used to address runoff quantity objectives, and ...

Development and Application of One Dimensional Multi-component Reactive Transport Models

Torlapati, Jagadish (2012-12-14)

The overarching goal of this dissertation is to develop reactive transport models and explore their applications to groundwater remediation problems. The primary focus of this dissertation is aimed at developing models ...

Development, Numerical Implementation, and Application of Methods to Simulate Solute Transport Processes in Porous Media Systems

Bedekar, Vivek (2019-04-16)

Solute transport in porous media has been the attention of a plethora of studies over the last several decades. This research identifies gaps in existing knowledge within the realm of solute transport in porous media systems ...

Enhancing Understanding of Mineral Surface Area in Fabricated and Real Sandstone

Salek, Md Fahim (2023-07-28) ETD File Embargoed

Carbon dioxide (CO2) capture and storage (CCS) is a well-developed technology to mitigate climate change associated with increasing CO2 due to anthropogenic activities. Injecting CO2 in subsurface porous rock formation ...

Evaluating alternatives for the implementation of Curve Number in SWMM for an urbanized watershed

Xiao, Han (2022-11-27)

Modeling hydrological abstraction, particularly infiltration, in urbanized areas is a complex task. Without field validation data, researchers and engineers often rely on readily available methodologies on semi-empirical ...

An Experimental Investigation on Air Pocket Entrapments Caused by Shear-Flow Instabilities in Rapid-Filling Pipes

Cetin, Merve (2019-08-08)

Rapid filling conditions in closed conduits, such as the case of sewer filling during intense rain events, can lead to air pocket formation. Such formation creates many operational issues in urban water systems, including ...

Experimental Investigations on pressure pulses through different porous media

Nicolaico, Gianlucca (2023-08-16)

Fluid mechanics traditionally and significantly investigate transient flows, which find applications ranging from flows in pipelines to porous media flows linked to water extraction and hydrocarbons. However, the nature ...

Field Investigations and SWMM Modeling of an Undeveloped Headwaters Catchment Located in the Lower Coastal Plain Region of the Southeast USA

Moynihan, Kyle (2013-11-05)

The southeastern region of the United States is host to a diverse variety of geophysical regions including the Blue Ridge, Piedmont, Inland Basins and Coastal Plains. Each region shows its own distinctive set of hydrological ...

A Finite Volume Implementation of the Shallow Water Equations for Boussinesq Gravity Currents

Hatcher, Thomas, Jr. (2012-07-16)

The shallow water equations (SWE) are a powerful tool for modeling the propagation of gravity currents (GC) because of their relative simplicity, computational efficiency and accuracy. Finite difference solutions, either ...
