Using Temporal Changes In Drought Indices To Generate Probabilistic Drought Intensification Forecasts, Jason A. Otkin, Martha C. Anderson, Christopher Hain, Mark Svoboda

National Drought Mitigation Center: Faculty Publications

In this study, the potential utility of using rapid temporal changes in drought indices to provide early warning of an elevated risk for drought development over subseasonal time scales is assessed. Standardized change anomalies were computed each week during the 2000–13 growing seasons for drought indices depicting anomalies in evapotranspiration, precipitation, and soil moisture. A rapid change index (RCI) that encapsulates the accumulated magnitude of rapid changes in the weekly anomalies was computed each week for each drought index, and then a simple statistical method was used to convert the RCI values into drought intensification probabilities depicting the likelihood that …

Decolorization Of Hair Dye By Lignocellulosic Waste Materials From Contaminated Waters, Habib Zahir, Michelle Naidoo, Rada-Mayya Kostadinova, Karla A. Ortiz, Rosario Sun-Kuo, Abel E. Navarro

Publications and Research

Basic yellow 57 (BY57) was chosen as a model hair dye due to its prevalence in cosmetics wastewaters. This study proposes the use of lignocellulosic materials like spent tea leaves of peppermint (PM), chai tea (CT), and chamomile (CM) as raw adsorbents for the removal of BY57 from contaminated solutions. Batch adsorption experiments were carried out at room temperature to achieve the maximum adsorption capacity. Results indicate that the highest removal is achieved at pH 6–8, with a minimum adsorbent mass of 75 mg and in the absence of salinity, crowding agents and heavy metals. Adsorption equilibria were modeled according …

A Fesability Analysis Of A Novel Constructed Wetland Design Tool For Arusha, Tanzania, Michael R. Sheehan

Open Access Theses

While water is a resource necessary for all life, in Tanzania alone over 20 million people who live in rural areas have no access to improved water sources. Water stress is a major concern in rural Tanzania, where annual potential evaporation can outpace precipitation by hundreds of mm per year. There is a significant need for improved access to water sources for Tanzanians living in rural regions of Arusha. To improve access to water, both water quantity and quality need to be addressed in a treatment system. Various water collection and treatment systems were compared and contrasted through the lens …

Systematic Analysis Of Drainage Events In Free Draining And Managed Subsurface Drainage Systems, Guy Bou Lahdou

Open Access Theses

Understanding the hydrologic controls that regulate outflow from free and managed subsurface drainage systems during drainage events can offer improved insight on the overall functioning and effectiveness of the systems so that they can be better managed or retrofitted to increase their environmental benefits. This study used drainage, precipitation, water table, and soil moisture data from a monitoring site located in east central Indiana to investigate the event hydrology of 22 drainage events in free and managed subsurface drainage systems. Relationships between event drainage volume, drain flow hydrograph metrics, column soil moisture, water table depth, and precipitation characteristics were explored …

Feasibility Of Mainstream Nitrite Oxidizing Bacteria Out-Selection And Anammox Polishing For Enhanced Nitrogen Removal, Pusker Raj Regmi

Civil & Environmental Engineering Theses & Dissertations

Short-cut nitrogen removal avoids nitrite oxidation to nitrate by nitrite oxidizing bacteria (NOB) and allows a) reduction of formed nitrite to nitrogen gas via heterotrophic denitrification and/or b) oxidation of remaining ammonia with formed nitrite to nitrogen gas via anaerobic ammonia oxidation (anammox). The precondition for achieving shortcut nitrogen removal is suppression of NOB, which is favored by warm and high ammonia strength conditions found in internally generated ammonia-rich waste streams through anaerobic digestion of waste solids referred to as sidestreams or reject water. The discovery of anammox bacteria in the mid-1990s, which are capable of transforming NH₄+ …

Evaluation Of The Epa Swmm Model To Simulate Low Impact Development Features In An Urban Stormwater Environment, Holly Ann Carpenter

Civil & Environmental Engineering Theses & Dissertations

This research thesis explores the use of the Environmental Protection Agency's (EPA) Stormwater Water Management Model (SWMM) to model an urban watershed with a developed stormwater management system and test the SWMM model's ability to simulate Low Impact Development (LID) features by proposing typical LID features that can be retrofitted to the developed study area. The SWMM model is established with an existing survey of the study area's stormwater management system, and due to the lack of field data for the study area, the model developed in this research thesis is calibrated with the consideration of a published stormwater model …

Analysis Of Landsat Satellite Data To Monitor Water Quality Parameters In Tenmile Lake, Oregon, Michael T. Waxter

Civil and Environmental Engineering Master's Project Reports

The health of North and South Tenmile Lakes in coastal Oregon has declined since the introduction of invasive species of fish and plant life in the 1920s. The lakes are now on the Federal Clean Water Act list of impaired water bodies due, in part, to a lack of dissolved oxygen and Hazardous Algae Blooms (HAB) blooms that occur during June through September. In this report we discuss the possibility of detecting and monitoring these blooms using satellite measurements of water surface color. In-situ measurements obtained from the Tenmile Lakes Basin Partnership were used to calibrate reflectance from the Thematic …

A Multi-Period Mixed Integer Linear Programming Model For Desalination And Electricity Co-Generation In Kuwait, Nael Abdulhameed Alqattan

USF Tampa Graduate Theses and Dissertations

Water is the root of life and the engine that drives agriculture, industry, economy and services. The demand for water often necessitates desalination, particularly in arid coastal environments where there are several desalination technologies in use today such as Multi-Effect Distillation (MED) and Reverse Osmosis (RO). The key utility requirement for technologies such as desalination and population in general include energy in one form or another. Therefore, desalination and co-generation are often integrated. Another key utility is electricity which is generated from either renewable or non-renewable sources. The demands for water and electricity change over time and are subject to …

Hydrostratigraphic Interpretation Of Test-Hole And Borehole Geophysical Data, Kimball, Cheyenne, And Deuel Counties, Nebraska, 2011-12, Christopher M. Hobza, Steven S. Sibray

United States Geological Survey: Water Reports and Publications

Recently (2004) adopted legislation in Nebraska requires a sustainable balance between long-term supplies and uses of surface-water and groundwater and requires Natural Resources Districts to understand the effect of groundwater use on surface-water systems when developing a groundwater-management plan. The South Platte Natural Resources District (SPNRD) is located in the southern Nebraska Panhandle and overlies the nationally important High Plains aquifer. Declines in water levels have been documented, and more stringent regulations have been enacted to ensure the supply of ground-water will be sufficient to meet the needs of future generations. Because an improved understanding of the hydrogeologic characteristics of …

Environment, Rights, And Waste In Bolivia: Addressing Water And Sanitation Processes For Improved Infrastructure, Maryann R. Cairns

USF Tampa Graduate Theses and Dissertations

Water and sanitation (WatSan) development projects impact both natural systems and societal structures where they are placed. A complex process of development, including inter-governmental policies, aid agencies, personal relationships, and community politics enhance and constrain the efficacy of these projects. This study presents the many ways in which the WatSan development process has unintended and unexpected returns for certain community groups. Using a political ecology framework, I look at power structures, perceived and projected environmental impacts, multiple stakeholders, and individual discourses to critique how the right to water and sanitation is implemented in a specific community context. This project advances …

Diffuse Nutrient Pollution From Residential Catchments, Melissa Rachelle Butcher

USF Tampa Graduate Theses and Dissertations

Nonpoint source nutrient pollution is diffuse pollution lacking discrete origin and conveyance. This thesis synthesizes and critically reviews research on residential nitrogen and phosphorus loss to stormwater runoff and leaching. The evaluation pulls from research covering influential socio-demographic indicators, such as use of lawn maintenance services and homeowner fertilizer practices. The extent to which such social and economic factors may influence the prevalence and fate of diffuse nutrients in stormwater runoff from residential areas has not been adequately established. Understanding the source and influencing factors of diffuse nutrient pollution is important in order to effectively protect surface and groundwater resources. …

The Role Of Water In The Rise, Prominence, And Decline Of Nabataean Petra, Dennis Cummins

Dissertations, Theses, and Capstone Projects

This paper evaluates the rise of Nabataean Petra, its prominence, and eventual decline. The predominant context is effective water management as a pivotal driving factor in the growth of the Nabataean kingdom, which fostered an environment in which its famous incense trade could develop. Rising incense demand was the catalyst for growth from the first century BC through the first century AD; in AD 106 when Rome annexed the Nabataean kingdom, Petra began its gradual decline. In AD 363 an earthquake destroyed much of the city, and Petra did not return to its earlier prominence. From the outset, water played …

A Combined Chemical And Biological Approach To Transforming And Mineralizing Pahs In Runoff Water, Chainarong Sakulthaew, Steve D. Comfort, Chanat Chokejaroenrat, Clifford Harris, Xu Li

School of Natural Resources: Faculty Publications

The water quality of lakes, rivers and streams associated with metropolitan areas is declining from increased inputs of urban runoff that contain polycyclic aromatic hydrocarbons (PAHs). Our objective was to transform and mineralize PAHs in runoff using a combined chemical and biological approach. Using ¹⁴C-labeled phenanthrene, ¹⁴C-benzo(a)pyrene and a mixture of 16 PAHs, we found that ozone transformed all PAHs in a H₂O matrix within minutes but complete mineralization to CO₂ took several weeks. When urban runoff water (7.6 mg C L−1) replaced H₂O as the background matrix, some delays in degradation rates …

The Impact Of Internet Gis On Access To Water Quality Information, Joseph H. Hoover

Electronic Theses and Dissertations

Empowering citizens to comprehend complex environmental issues affecting their daily lives is essential to sustaining a healthy and informed public. The work of many environmental nongovernmental organizations (ENGOs) and institutions of higher education (IHEs) center around helping their stakeholders become informed of, and in turn, better understand complex environmental problems. However, providing individual stakeholders with knowledge about environmental issues that is easily accessible and understandable represents a recurring challenge in today's society. As a result, a gap continues to exist between that which is known about environmental problems and the public's awareness and understanding of those issues. Arsenic contamination of …
