A Report On The Gascoyne River Catchment Following The 2010/11 Flood Events, Peter-Jon A. Waddell, P W.E Thomas, Paul A. Findlater

Resource management technical reports

In December 2010 an extreme tropical storm resulted in widespread flooding at Carnarvon and across the catchment. Another two flood events followed during the summer of 2010–11

The rationale for this assessment is to provide illustrative evidence on the role that perennial vegetation groundcover management has in influencing the risk of flooding and soil loss in the catchment. It may be possible that the impact of flooding associated with extreme storm events can be reduced. This report focuses on catchment condition and is not a review of the pastoral industry’s economic viability.

An Education On Growing Water Scarcity And The Benefits Of Domestic Greywater Recycling Systems, Patricia Cates

Natural Resources Management and Environmental Sciences

Water scarcity is becoming an ever growing concern in the world today. Fresh potable water is a natural resource which is being used more rapidly than it is being replenished. A growing global population, agriculture, and industry have placed great demands on our water resources. There is a need to help conserve our planet’s fresh water reserves. A tremendous percentage of household drinking water in the United States is currently being used to flush toilets, water yards and wash laundry or dishes. A practice termed ‘greywater recycling’ allows a person to utilize slightly used water to irrigate landscapes and flush …

Synergy Of Alum And Chlorine Dioxide For Curbing Disinfection Byproduct Formation Potential At Central Arkansas Water, Corey W. Granderson

Graduate Theses and Dissertations

Central Arkansas Water (CAW), the water utility for Little Rock, AR, draws their source water from Lake Maumelle and Lake Winona. To curb disinfection byproduct (DBP) formation, CAW has begun retrofitting their two plants to use chlorine dioxide as an alternative primary disinfectant followed by free chlorine secondary disinfection in the distribution system. In this study, fluorescence parallel factor (PARAFAC) analysis was combined with free chlorine simulated distribution system (SDS) tests and DBP formation potential (DBPFP) tests to study the benefit of chlorine dioxide primary disinfection (CDPD) with alum coagulation. Of the DBPs screened, trichloromethane (TCM) was formed in highest …

Limestone-based material has demonstrated the potential to reduce select metals (lead, cadmium and arsenic) in drinking water, with the additional benefit of …

Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson

Pitzer Senior Theses

The issue of sediment removal from the San Gabriel Mountains has been a complex issue that has created problems with beach replenishment, habitat destruction and the need to spend millions of dollars at regular intervals to avoid safety hazards. Most recently 11 acres of riparian habitat, including 179 oaks and 70 sycamores, were removed for sediment placement. Other sites including Hahamongna Watershed Park and La Tuna Canyon also face a similar fate. This thesis questions: How did we get to this point of destroying habitat to dump sediment which is viewed as waste product? What are the barriers for creating …

Arsenic Contamination In Groundwater In Vietnam: An Overview And Analysis Of The Historical, Cultural, Economic, And Political Parameters In The Success Of Various Mitigation Options, Thuy M. Ly

Pomona Senior Theses

Although arsenic is naturally present in the environment, 99% of human exposure to arsenic is through ingestion. Throughout history, arsenic is known as “the king of poisons”; it is mutagenic, carcinogenic, and teratogenic. Even in smaller concentrations, it accumulates in the body and takes decades before any physical symptoms of arsenic poisoning shows. According to the World Health Organization (WHO), the safe concentration of arsenic in drinking water is 10 µg/L. However, this limit is often times ignored until it is decades too late and people begin showing symptoms of having been poisoned.

This is the current situation for Vietnam, …

Take Me To The River: Revitalizing La's Lost Monument, Erin Childs

Pomona Senior Theses

The tale of South Korea's Cheonggyecheon River is one to warm an urban environmentalist's heart. Cheonggyecheon runs through the center of Seoul, a bustling metropolis of ten million that has been the capital of Korea since the 14th century. The Japanese were the first to sacrice Cheonggyecheon on the altar of urbanization, turning the River into a sewage system during their 35 year occupation between 1910 and 1945. Already thusvdegraded, it was easy for later administrations to eventually completely cover the river with the Cheonggye Road and Cheonggye Elevated Highway between 1958 and 1976. Cheonggyecheon became an exemplar of the …

Factors Influencing The Distribution Of Brown Trout (Salmo Trutta) In A Mountain Stream: Implications For Brown Trout Invasion Success, Christy Meredith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brown trout (Salmo trutta), one of the world’s most successful introduced species in river and lake systems, negatively impacts native species through predation, competition, and systemwide effects. Thus, there is a need to understand factors controlling the distribution of brown trout, in order to prioritize and develop conservation and management strategies. Within the context of invasion success, I investigated how the physical characteristics of the Logan River influence the distribution of brown trout, as well as the potential for brown trout predation on a native fish, the mottled sculpin (Cottus bairdi).

In chapter 1, I evaluated …

The Influence Of Geology And Other Environmental Factors On Stream Water Chemistry And Benthic Invertebrate Assemblages, John R. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Determining if a stream has been degraded by human activities requires knowing what that stream’s natural water quality and freshwater species composition would likely be without any alteration. However stream natural conditions vary greatly from stream to stream, making predicting natural conditions difficult. To determine natural stream conditions, I developed models to predict natural stream water chemistry at individual streams across the western USA. Specifically, the models predict a stream’s electrical conductivity (a measure of the amount of solids dissolved in water), acid neutralization capacity, and concentrations of calcium, magnesium, sulfate, total phosphorus, and total nitrogen. These models predict chemistry …

Environmental Assessment Of Streams: Linking Land Use, Instream Stressors, And Biological Indices To Infer Likely Causes Of Ecological Impairment, Jacob J. Vander Laan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To protect and restore stream biota, managers need to be able to both detect biological degradation and infer likely causes of impairment. Managers commonly develop indices based on stream biota to assess the biological condition of streams. However, the performance of these indices dictates the ability to detect degradation, and although index performance varies widely, the sources of this variation are often unclear. In addition, bioassessments do not identify causes of impairment. My thesis research had two general goals: 1) develop indices to measure biological condition in Nevada streams and 2) quantify relationships between land uses, stressors, and biological condition …

Nutrient Dynamics In Stormwater Runoff From Green Roofs With Varying Substrate, John Michael Fohner

Graduate Theses and Dissertations

One major concern with urban development is the increasing amount of stormwater runoff from large expanses of impervious surfaces. These impervious surfaces reduce the ability of stormwater to infiltrate into the soil and eventually groundwater, which leads to greater amounts of surface runoff. Green technology serves as a viable solution to many of the environmental problems presented by modern development. Fifteen mock, extensive green roofs were built in the fall of 2008 at the Watershed Research and Education Center in Fayetteville, Arkansas. The goals of this project were to (1) measure the amount of stormwater runoff from varying treatments and …

Impact Of Sludge Treatment Processes On Estrogen Concentration In Wastewater Sludge, Erica Marti

College of Engineering: Graduate Celebration Programs

Endocrine-disrupting compounds (EDCs), such as estrogen, are known to be present in the aquatic environment at concentrations that affect fish and other wildlife. For example, juvenile male fish exposed to estrogen will synthesize vitellogenin, which is a female-specific protein. Estrogen exposure is also linked to sex reversal, intersexuality, and inhibition of gonadal growth (Jobling et al., 1996).

Wastewater treatment plants are major contributors of EDCs into the environment. EDCs end up in wastewater as a result of natural excretion from the body or being washed off the skin. WWTPs are not designed to remove these substances. As a result, EDCs …

Clean Water In Haiti, Hannah Mchugh

2012 Awards for Excellence in Student Research & Creative Activity - Documents

In the past few years, Haiti has been a topic that has been in the news here in the United States for many reasons. These reports typically show the faces of hundreds of starving and injured Haitians who live in turmoil and they discuss the disasters that have befallen the country. While these reports do not usually show the more pleasant aspects, they are relatively accurate in showing the state of the majority of the country. A major impact on a country that is in such a dire state is the presence and availability of clean water. But to understand …

Nantucket Shellfish Management Plan, Kristin Uiterwyk, Steve Bliven, Dan Leavitt, Jack Wiggin, Urban Harbors Institute, University Of Massachusetts Boston

Office of Community Partnerships Posters

Nantucket’s shellfish resources are an important part of the Island’s history, culture, and economy. Nantucket waters support one of the country’s last wild-caught bay scallop fisheries. Elsewhere along the Atlantic coast, fishing pressure, habitat loss, and disease have severely depleted bay scallop populations. Although Nantucketers continue to make a living harvesting shellfish from the Island’s waters, many do so with concern for the future of the resources and the habitats that support them. Urban Harbors Institute (UHI) provided technical assistance to the community to develop a Shellfish Management Plan (SMP) that addresses issues of water quality, habitat loss, climate change, …

Sharing Earth’S Most Valuable Resource: Cooperation In Transboundary Water Management, Olivia Nesbit

Independent Study Project (ISP) Collection

Natural resources in general and water in particular are undeniably essential to human growth and development. However, in recent years, with rising demands for freshwater, sky-rocketing population growth rates, climate change, shrinking water resources and poor water management, scarcity of this critical resource is a growing problem around the world. A high percentage of the most severe water scarcity is due primarily to mismanagement and ineffective allocation of water resources. There is an overarching legal framework to govern the management of water internationally. The UN Watercourses Convention and the UNECE Water Convention are the two most important documents that govern …

Confronting Agrarian Crisis And Deconstructing Farmer Debt: The Story Of Sulthanpur Village, Andhra Pradesh, Erica Dejong

Independent Study Project (ISP) Collection

In a climate of globalized politics and neoliberal economics, it can be difficult to isolate the impacts of agricultural and economic policy on the lives of the rural poor in India. Hidden behind a veil of economic growth, pro urban, and pro industry governments, the stories of small and marginal farmers have been overlooked in the name of different development priorities. This study endeavors to put the agrarian poor back into the scholarship spotlight by deconstructing livelihood crises and farmer debt in Sulthanpur Village, Andhra Pradesh. This effort is important because although Andhra Pradesh has the highest rate of farmer …

Assessing The Viability Of Desalination For Rural Water Supply In Chwaka, Zanzibar, Roy Yu, Daniele Packard

Independent Study Project (ISP) Collection

Zanzibar has been struggling with water scarcity issues over the last few decades due to an increase in consumption on the island and a deterioration of existing supply infrastructure. Poor distribution has affected rural communities most, due to their absence of tourism development, which has gone hand in hand with infrastructure establishment. Foreign aid has begun to address the issue by investing in alternative forms of water supply. On November 15, 2011, The Minister for Housing, Lands, and Water, Ali Juma Shamhuna inaugurated the Mörk desalin® RO 100 SW desalination machine, a solar and wind powered desalination unit in Chwaka …

A Meta-Analysis Of Alternative Water Sources, Katie Colton

Honors Projects in History and Social Sciences

Roughly one half of the Earth’s population suffers from shortage or lack of clean water. While many innovations and products have been created to address this Global Water Crisis, no comparisons have been done as to which innovations and products are the best overall choice for philanthropic investment. The crisis can be broken down into three specific crises including the transportation crisis, the access crisis, and the sanitation crisis. The study examined fifteen innovations and products, targeted to address the three crises to determine which innovation in each group is the overall smart investment. Pulse tool was used to create …

Water And Energy Balance Response Of A Riparian Wetland To The Removal Of Phragmites Australis, Phillip Mykleby

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Vegetation and climate both play integral roles in water availability, particularly for arid to semi-arid regions. Changes in these variables can lead to extreme shortages in water for regions that rely on water for crop irrigation (i.e., the Great Plains). The objective of this study is to evaluate the impacts of vegetation on water availability in the Republican River basin in central Nebraska. Decreases in streamflow have been observed in the river basin for many years and, as a result, an invasive riparian plant species (Phragmites australis) is being removed in an effort to reduce evapotranspiration and reclaim …

Time-paced, fixed volume composite samples were collected during storm events at the inlets and outlet of the CSWQF and at the inlets and outlet of each treatment train component of the FCWQF. In addition, long-term data collected at the FCWQF was analyzed. Composite data collected during November 2-3, 2011 and March 5-6, 2012 showed that the treatment trains can measurably reduce the event mean concentration …

Optimization Of Nanoscale Zero-Valent Iron For The Remediation Of Groundwater Contaminants, Andrew W. E. Mcpherson

Theses and Dissertations

Nanoscale zero-valent iron (nZVI) is an emerging tool for the remediation of groundwater contaminants. The nanoparticles are capable of reductively destroying or immobilizing a wide range of contaminants. Their small size results in a high surface area to mass ratio, making them much more reactive compared to their more-coarse predecessors. Small particle size also allows nZVI particles to be injected directly into contaminated areas via a well, limiting the above-ground footprint and allowing access to contaminated areas that are beyond the reach of some conventional methods. nZVI technology has the potential to facilitate remediation in difficult situations, improve remediation outcomes, …

Examining The Economic Costs And Sources Of Potable And Nonpotable Water In Northern Mexico, Kathryn Marie Marlor

USF Tampa Graduate Theses and Dissertations

Water availability and the cost of different water sources have been studied at great length. However, information is still needed to determine the policy directions to be undertaken by nations that have not yet achieved universal coverage of an improved water source. To further examine differences in water availability and pricing in the context of the developing world, three communities in Northern Mexico were surveyed to determine the differences in water distribution schemes and associated costs between rural and urban centers. It was observed that rural communities without a piped water supply paid 13 percent more for potable water supplies …
