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 ...

Assessing Performance Characteristics of Sediment Basins Constructed in Franklin County, Alabama

Logan, Christopher (2012-11-12)

The objective of the research project was to monitor the performance of newly designed sediment basins that were constructed on the ALDOT 502 project in Franklin County. The project included four tasks: (1) assess performance ...

Comparative Analysis of Soil Erosion Using Large-, Intermediate-, and Small-Scale Test Plots of Bare Soil and Different Hydromulch Products under Large-Scale Rainfall Simulator

Ricks, Matthew Dale (2020-12-10)

A study was conducted to compare the test results of three different size erosion-control plots under rainfall simulation to determine if there is a direct relationship to the size of a tested erosion-control plot and the ...

Construction and Calibration of Large-Scale Rainfall Simulators

Etheridge, Jacob (2023-04-24)

Large-scale rainfall simulation offers valuable insight into the effectiveness of erosion control practice. While small and intermediate-scale apparatuses can analyze the effects of splash and sheet erosion on a slope, ...

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 ...

Determining the Average Available Workdays for ALDOT Construction Projects

Mejia Reyes, Esthefany Marien (2023-12-01)

Construction scheduling in the dynamic field of highway projects is complex and time-consuming, with project delays and cost overruns setting critical challenges. This study highlights the significance of accurately ...

Development of Guidance for Runoff Coefficient Selection and Modified Rational Unit Hydrograph Method for Hydrologic Design

Dhakal, Nirajan (2012-05-07)

The rational method is the most widely used method by hydraulic and drainage engineers to estimate design discharges. The runoff coefficient (C) is a key parameter for the rational method. Literature-based C values (Clit) ...

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 ...

Drought Forecasting for Small to Mid-sized Communities of the Southeast United States

Sharda, Vaishali (2012-05-07)

Most of the climate variability in the Southeast United States has been attributed to El Niño Southern Oscillation (ENSO) and this climate variability has resulted in increased the stress on water resources of the region ...

The Effect of Grid Resolution on Hydrodynamic Modeling of Biscayne Bay

Nwogwu, Nathaniel (2024-01-08)

Environmental Fluid Dynamics Code Plus (EFDC+) is a model that has been proven to be effective in hydrodynamic simulation. Understanding water surface elevation (WSE) and salinity dynamics in estuaries is crucial for ...

Effect of hydrologic and hydraulic calculation approaches on pier scour estimates

Castaneda Galvis, Luis Fernando (2023-12-05)

Bridge scour, a phenomenon characterized by the erosion and removal of sediment from the vicinity of bridge foundations, is a significant concern in the fields of civil engineering and infrastructure management. There are ...

The Effects of Land Cover, Climate, and Urbanization on Groundwater Resources in Dauphin Island

Petty, Katherine (2011-11-21)

The effects of land cover change, climate change, and population growth on the groundwater resources of a barrier island were explored in this study. The relationship between land cover and groundwater recharge was studied ...

Enhancement and Redevelopment of the Regional Lake Water Quality Model with Applications

Tasnim, Bushra (2020-08-17)

Water quality is a serious issue in most of the world in the 21st century. Many lakes are impaired with Harmful Algal Blooms (HABs). To provide better lake management and restoration, modeling of lakes is of utmost importance. ...

Evaluating and Understanding of Bridge Scour Calculation

Pokharel, Sudan (2017-11-27)

Channel scour and channel instability at bridges are the major cause of bridge collapse caused by flooding. Currently, Departments of Transportation (DOTs) in the USA use the HEC-18 procedure and associated software, which ...
