Application and Evaluation of WEPP in a Forested Watershed with Perennial Streams

Srivastava, Anurag (2010-01-06)

Forests generally have low erosion rates unless they are disturbed by harvesting operations or road construction. These common disturbances typically cause increase in the sediment yield which is reduced after vegetation ...

Assessment of Composting Methods for Use in the Green Industry

Brymer, William (2008-12-15)

Composting is a common waste management tool for successful reduction of waste materials. Due to increased consumer awareness for compost products and their value to the green industry research is needed to evaluate different ...

Assessment of Precision Technologies for Accurate Delivery of Crop Inputs

Harbuck, Tyrel (2010-05-14)

At the Tennessee Valley Research and Extension Center (TVREC), Belle Mina, Alabama, Global Positioning System (GPS)-assisted machine guidance and subsurface drip irrigation (SDI) have been implemented to study precision ...

Beyond The Pit [of Democracy]: Mine Reclamation, Emergence, and Finite Resources

Ballard, Daniel (2013-03-18)

Through the integration of democratic process with that of the reclamation of the Martin-Marietta Aggregate Quarry (MMQ), my design research proposes that it is possible to positively change contemporary understanding of ...

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, ...

Comparing Economic Returns of Dissolved Oxygen Management in Commercial Catfish Production

Holland, Leigh Wilson (2016-05-02)

Catfish culture is one of the largest forms of aquaculture in the US. Catfish production systems have been able to achieve production up to almost 12,000 kg ha-1 year-1 (Bott, 2015) since the increase in availability of ...

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 ...

Evaluating Maintenance Techniques for Long-Term Vegetation Establishment on Disturbed Slopes in Alabama

Messer, Richard Clay (2011-06-28)

Sustainability of common bermudagrass on formerly disturbed slopes in Alabama has proven to be a difficult task in some cases. Failures of once successful stands of bermudagrass can be seen throughout Alabama on road ...

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) ...

Hydraulic Management of SDI Wastewater Dispersal in an Alabama Black Belt Soil

He, Jiajie (2009-12-11)

Approximately 52% of the 14000 km2 Alabama Black Belt region is unsuitable for conventional onsite wastewater treatment systems because of low hydraulic permeability, high water table, or other restrictive soil properties. ...

Improvements in the Design and Application of Erosion and Sediment Control Technologies for the Construction Industry

Perez, Michael (2016-12-07)

Erosion and sediment controls (ESCs) have become essential components of construction related activities. Stormwater pollution prevention regulations are the principal catalysts driving the development of new ESC practices ...

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 ...

Nutrient Uptake and Plant Selection in Southeastern Rain Gardens

Jernigan, Kathryne (2010-08-13)

A bioretention rain garden is an innovative stormwater management practice that integrates stormwater infiltration and storage to improve the quality of runoff. Part1. Two bioretention rain garden designs constructed at ...

Performance Evaluations of Sediment Barrier Practices and Unmanned Aircraft System Mapping Technologies

Whitman, Jarrell (2018-11-15)

Sediment barriers are sediment control practices typically installed along the perimeter of construction sites that are intended to intercept, capture, and temporarily contain sheet to shallow concentrated flows prior to ...
