Anthropogenic and Climate Impacts on Groundwater Resources in the Lower Apalachicola-Chattahoochee-Flint River Basin

Mitra, Subhasis (2015-01-07)

El Niño Southern Oscillation (ENSO) is one of the major climate variability cycles around the world and is responsible for droughts in the Southeast United States. These ENSO-induced droughts have been responsible for ...

Climate Change Implications on Rainfall Erosivity and Intensity Duration Frequency Curves over the Southeast United States

Takhellambam, Bijoychandra Singh (2023-08-04) ETD File Embargoed

Climate change impacts on precipitation characteristics will alter the hydrologic characteristics, such as peak flows, time to peak, and soil erosion potential. However, many of the currently available climate change ...

Climate Variability and Irrigation Impacts on Stream-Aquifer Dynamics in the Apalachicola-Chattahoochee-Flint River Basin

Singh, Sarmistha (2015-08-18)

Climate variability cycles are responsible for short term fluctuations in climatic conditions thereby, affecting the water cycle and the availability of freshwater resources around the world. In Southeast United States, ...

Data-Driven Agroclimate Modeling and Forecasting Based on Earth Observations and Predictions: A Study of Evapotranspiration, Precipitation, and Crop Yields

Medina, Hanoi (2020-04-17)

Meeting the growing food demand in a sustainable manner is the main challenge faced by agriculture, at a time when the climate changes increasingly threaten food security. Innovative agro-climate approaches are needed to ...

Development of Reliable Erosion Indices for Climate-Informed Soil Conservation in the Southeastern United States

McGehee, Ryan (2016-12-09)

A new methodology and corresponding dataset are recommended for a more accurate calculation of erosion index (EI) and erosivity (R) that was more consistent with observations from superior data sources. NOAA NCDC DSI-3260 ...

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 ...

An Ecologically-Sustainable Surface Water Withdrawal Framework For Cropland Irrigation-A case study in Alabama

Gupta, Anand (2009-04-22)

Agricultural production in the State of Alabama, USA, mostly depends on natural rainfall. Because of this and also because of low and uncertain precipitation levels during growing seasons, agricultural production in Alabama ...

Evaluating the Impact of Climate Change on Rainfall Intensity-Duration-Frequency (IDF) Curves in Alabama Using Dynamically-Downscaled Precipitation Data

Mirhosseini, Golbahar (2013-07-19)

Rainfall intensity-duration-frequency (IDF) curves are extensively used for hydrologic designs. A design based on inaccurate rainfall characteristics can lead to malfunction of infrastructure, excessive ...

Evaluating Water Quality Impacts of Alternative Management Practices through Development of a BMP Database

Butler, Gary (2007-08-15)

Agriculture and forestry are two important industries in the State of Alabama, and each is historically known to cause nonpoint source (NPS) pollution problems. Currently, the U.S. Environmental Protection Agency (USEPA) ...

Evaluation of Erosion and Sediment Control Best Management Practices: Use of Silt Fence Tieback Systems and Anionic Polyacrylamide on Highway Construction Sites

McDonald, Justin (2007-08-15)

Every year the construction process exposes millions of acres of earth to the elements of wind, rain, and snow. This greatly increases the potential for erosion; therefore, the need for efficient erosion and sediment ...

Evaluation of Soil Effects on Soil Erosion on Off-Road Vehicle Trails using WEPP

Melton, Jonathan (2008-05-15)

Erosion and sediment loss from the use of off-road vehicles (ORV) is an escalating problem on national forest lands. The increasing number of ORV riders coupled with decreasing riding areas has caused the United States ...

The Fate and Transport of the Antimicrobials Sulfadimethoxine and Ormetoprim in the Environment

Sanders, Sarah (2007-05-15)

Over the past decade, there have been increasing concerns regarding antimicrobial contaminants in the environment. To date, there exists limited research regarding the fate of these compounds in the environment once ...

Flood Control in Toulmins Spring Branch Watershed through LID Practices

Baltaci, Enis (2016-08-03)

Urbanization is known to cause increases in volume of stormwater runoff and peak flow rates, which leads to changes in natural flow regime and increases the likelihood of flooding. Conventional stormwater management practices ...

Identifying Critical Source Areas of Sediment, Nitrogen and Phosphorus: A Modeling Approach

Niraula, Rewati (2010-08-25)

Impairment in the quality of water due to nutrients and sediments originating from watersheds is a serious problem in the USA and the world. Identification of critical source areas (CSAs), which contribute most of the ...

Incorporating El Niño Southern Oscillation (ENSO)-Induced Climate Variability for Long-Range Hydrologic Forecasting and Stream Water Quality Protection

Sharma, Suresh (2012-08-02)

El Niño Southern Oscillation (ENSO) has been found to have a strong predictable effect on streamflow in different parts of the world. Since ENSO has potential relationship to seasonal and inter-annual variability in ...

Influence of climate variability on the ecologically sustainable water withdrawals from streams for irrigation

Sangha, Laljeet (2019-07-10)

Alabama (AL) receives a large amount (1270-1727 mm annual average) of rainfall annually. However, much of the rainfall occurs in the non-crop growing season (winter months), and recurring, severe droughts during the crop ...
