A Watershed Scale Evaluation Of Selected Second Generation Biofeedstocks On Water Quality, Gurdeep Singh
A Watershed Scale Evaluation Of Selected Second Generation Biofeedstocks On Water Quality, Gurdeep Singh
Graduate Theses and Dissertations
This study compares a novel simulation approach to the conventional Soil and Water Assessment Tool (SWAT) modeler's approach for targeting biofuel crop production on marginal lands. In conventional SWAT modeling approach, non-spatial definition of hydrological response units (HRUs) results in the simulation of biofuel crops on both marginal and non-marginal land. This study provides an alternative approach in which a marginal-land raster was integrated into the land use and land cover (LULC) raster in such a way that the land uses were divided into marginal and non-marginal components. This modified LULC was used for model setup which resulted in marginal …
Mathematical Modeling Of Fluid Spills In Hydraulically Fractured Well Sites, Oluwafemi Michael Taiwo
Mathematical Modeling Of Fluid Spills In Hydraulically Fractured Well Sites, Oluwafemi Michael Taiwo
Graduate Theses and Dissertations
Improved drilling technology and favorable energy prices have contributed to the rapid pace at which the exploitation of unconventional natural gas is taking place across the United States. As a natural gas well is being drilled, reserve pits are constructed to hold the drilling fluids and other materials returned from the drilling process. These reserve pits can fail, and when they do, plant and animal life of the surrounding area may be adversely affected. This project develops a screening tool for a suitable location for a reserve pit. This work will be a critical piece of the Infrastructure Placement Analysis …
Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson
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 …

Climate Change In Cyprus – Impacts And Adaptation Policies, Elpida Shoukri, Theodoros Zachariadis
Climate Change In Cyprus – Impacts And Adaptation Policies, Elpida Shoukri, Theodoros Zachariadis
Theodoros Zachariadis
This report provides a literature review of climate change facts and projections globally, for Europe, Mediterranean and Cyprus until the end of the 21st century. It focuses on climate change effects in Cyprus by sector and presents specific recommendations on the implementation of a proper adaptation strategy. The report is based on a review of the most important recent studies on climate change, including reports from international organizations as well as European and Mediterranean authorities and research institutions. The report has also benefited from information gathered through personal communication of the authors with public authorities, non-governmental organizations and researchers.
A Review Of National Msw Generation Assessments In The United States, David J. Tonjes, Krista L. Greene
A Review Of National Msw Generation Assessments In The United States, David J. Tonjes, Krista L. Greene
Technology & Society Faculty Publications
Municipal solid waste (MSW) is generated in very large quantities (probably, between 200 and 400 million tonnes per year) in the United States (US). MSW is generated at millions of places and there is no one precise, general definition for MSW that is generally applied, despite US Environmental Protection Agency efforts. As an element of both commerce and politics, reporting may be framed towards particular ends. Therefore, the two best known assessments of the quantity of US MSW production differ by approximately 50%. The assessors understand some of the reasons for the differences, but our analysis suggests that there are …
Beyond Business-As-Usual: Achieving A Paradigm Shift Towards Low-Carbon Transport, Theodoros Zachariadis
Beyond Business-As-Usual: Achieving A Paradigm Shift Towards Low-Carbon Transport, Theodoros Zachariadis
Theodoros Zachariadis
Transportation is responsible for a continuously rising share of global carbon emissions. Carefully designed regulations, supported by land use strategies, fiscal policies and local incentives, and enabled through targeted international development assistance, can reverse these unsustainable trends.

Climate Change In Cyprus: Impacts And Adaptation Policies, Theodoros Zachariadis
Theodoros Zachariadis
This paper provides an overview of facts and projections related to climate change in Cyprus until the end of the 21st century. It highlights the main climate change impacts foreseen and presents recommendations for the preparation of a national adaptation strategy. Coping with climate change is possible, provided that proactive actions are taken by both the public and the private sector. Public authorities need to set clear priorities and implement well designed policies. Most importantly, adequate monitoring mechanisms should be set up in order to provide much needed data which can send early warnings to policy makers and the public …

Sustainable Water Management In The University Of Texas At El Paso, Cora Martinez
Sustainable Water Management In The University Of Texas At El Paso, Cora Martinez
Open Access Theses & Dissertations
This thesis showed how to improve water and financial savings for UTEP and El Paso by improving water conservation and sustainability of the UTEP campus. The goals of this research were successfully accomplished by focusing in three principal objectives.
1. Analyze historical data of water consumption of the UTEP campus for the past decade.
2. Evaluate water consumption to quantify water consumption by buildings and type of use, as well as provide recommendations for water and cost savings.
3. Synthesize a water management framework within the UTEP Facilities' Geographic Information System (GIS) for long-term monitoring and evaluation
Water Mass Balances For The Rio Grande/Bravo From Fort Quitman, Texas To Foster Ranch Near Langtry, Texas: An Assessment Of Factors, Ramiro Lujan
Open Access Theses & Dissertations
ABSTRACT
Water availability is declining in many regions of the planet, particularly in arid and semi-arid regions. Water bodies located in these regions, like the Rio Grande/Bravo at the U.S. - Mexico border, are subjected to high water demands. This research project makes an assessment of the spatial and temporal variability of elements intervening in the water mass balance for the section of the Rio Grande/Bravo between Fort Quitman and Langtry, Texas during the time period extending from January 1990 through December 2005. This document mentions the main Rio Grande/Bravo stakeholders from the U.S. and Mexico, and describes issues related …

2012 Nebraska Groundwater Quality Monitoring Report
2012 Nebraska Groundwater Quality Monitoring Report
Nebraska Department of Environmental Quality: Reports
The 2001 Nebraska Legislature passed LB329 (Neb. Rev. Stat. §46-1304) which, in part, directed the Nebraska Department of Environmental Quality (NDEQ) to report on groundwater quality monitoring in Nebraska. Reports have been issued annually since December 2001. The text of the statute applicable to this report follows: “The Department of Environmental Quality shall prepare a report outlining the extent of ground water quality monitoring conducted by natural resources districts during the preceding calendar year. The department shall analyze the data collected for the purpose of determining whether or not ground water quality is degrading or improving and shall present the …

Hydrogen Production From Biogas By Oxy-Reforming: Reaction System Analysis, Aleksandra Terlecka, Wojciech M. Budzianowski
Hydrogen Production From Biogas By Oxy-Reforming: Reaction System Analysis, Aleksandra Terlecka, Wojciech M. Budzianowski
Wojciech Budzianowski
Oxy-reforming is emerging as an interesting alternative to conventional methods of hydrogen generation. The current article characterises this process through analysis of individual reactions: SMR (steam methane reforming), WGS (water gas shift) and CPO (catalytic partial oxidation). Analyses relate to optimisation of thermal conditions thus enabling cost-effectivenes of the process.
