A Fusion Of Remotely Sensed Data To Map The Impervious Surfaces Of Growing Cities Of Punjab, Pakistan, Binita Shrestha
A Fusion Of Remotely Sensed Data To Map The Impervious Surfaces Of Growing Cities Of Punjab, Pakistan, Binita Shrestha
UNLV Theses, Dissertations, Professional Papers, and Capstones
Urban population is expected to exceed 70% of the world’s total by the middle of the 21st century. Thus, growth in number as well as the sizes of the cities are certain in the near future. The urbanization rates will be much higher in the developing countries than the developed. Such phenomena are accompanied by conversion of land cover from its natural use to built up environment to accommodation growing population. Built up surfaces include road networks, buildings, parking lots and pathways. They are permanently impervious and hydrologically active surfaces. Large volume and discharges of runoff characterize impervious surfaces with …
From Access To Excess: Agribusiness, Federal Water Programs, And The Historical Roots Of The California Water Crisis, Tracy Marie Neblina
From Access To Excess: Agribusiness, Federal Water Programs, And The Historical Roots Of The California Water Crisis, Tracy Marie Neblina
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this paper is to show the link between water use, land consolidation, agribusinesses, and the water crisis that California began to experience in 2011. In order to better understand the relationship between the growth of agribusiness in the state and the evolution of water policy, this paper explores the historical context of land policy, the growth of farming in the San Joaquin Valley, and the development of federally funded water projects in the Central Valley. Years of expanding farmland and use of surface and underground water with limited regulation played an important role in exacerbating California’s water …
Investigating The Impacts Of Conventional And Advanced Treatment Technologies On Energy Consumption At Satellite Water Reuse Plants, Jonathan Roy Bailey
Investigating The Impacts Of Conventional And Advanced Treatment Technologies On Energy Consumption At Satellite Water Reuse Plants, Jonathan Roy Bailey
UNLV Theses, Dissertations, Professional Papers, and Capstones
With the ever increasing world population and the resulting increase in industrialization and agricultural practices, depletion of two of the world's most important natural resources, water and fossil fuels, is inevitable. Water reclamation and reuse is the key to protecting these natural resources. Water reclamation using smaller decentralized wastewater treatment plants, known as satellite water reuse plants (WRP), have become popular in the last decade. With stricter standards and regulations on effluent quality and requirements for a smaller land footprint (i.e. real estate area), additional treatment processes and advanced technologies are needed. This greatly increases the energy consumption of an …
Changing Climatic Conditions In The Colorado River Basin: Implications For Water Resources Management In The Las Vegas Valley, Srijana Dawadi
Changing Climatic Conditions In The Colorado River Basin: Implications For Water Resources Management In The Las Vegas Valley, Srijana Dawadi
UNLV Theses, Dissertations, Professional Papers, and Capstones
Climate change affects the water available in a region. It also affects the water demand, because of the increase in temperature. A system dynamics model was developed for the Colorado River Basin (CRB), operating at a monthly time scale, to assess the potential impacts of climate change on streamflow in the Colorado River and its subsequent impact on the water resources management in the Las Vegas Valley (LVV). The effect of climate change on streamflow was evaluated using 16 global climate model outputs for 3 emission scenarios, also referenced in the Inter-Governmental Panel on Climate Change Fourth Assessment Report. Risk …
Development Of A Sustainable Water Resource Financing Mathematical Model For Donors And End-Users, Sahar Zavareh
Development Of A Sustainable Water Resource Financing Mathematical Model For Donors And End-Users, Sahar Zavareh
UNLV Theses, Dissertations, Professional Papers, and Capstones
Rural villages and underdeveloped communities represent the largest group challenged by poor water supply and sanitation with inequalities in resources to adequately implement potential solutions and even more with their high risk level of financing, funding is particularly challenging for water projects. Innovative financing alone will not eliminate the burdens of rural villages and underdeveloped communities. The purpose of this thesis is to address the lack of sustainable water financing of water projects in rural areas using a novel framework of a mathematical model based on "system dynamics" using optimal feedback control theory to maximize the performance of a water …
Evaluating The Energy And Carbon Footprint Of Water Conveyance System And Future Water Supply Options For Las Vegas, Nevada, Eleeja Shrestha
Evaluating The Energy And Carbon Footprint Of Water Conveyance System And Future Water Supply Options For Las Vegas, Nevada, Eleeja Shrestha
UNLV Theses, Dissertations, Professional Papers, and Capstones
Water production requires the use of energy to transport water from distant locations, pump groundwater from deep aquifers and treat water to meet stringent drinking water and wastewater regulations. Energy production based on its source involves the emission of greenhouse gases also known as carbon footprint, which is the leading cause of global warming and climate change. Because of growing concerns of global warming due to these emissions, water providers are required to analyze the energy and associated carbon footprint of existing water production facilities and future water supply options. A system dynamics model is developed to estimate the energy …
Perception Of Ecological Risk To Water Environments And How It Affects Water Consumption And Water Resource Management In Southern Nevada, Tanju Kiriscioglu
Perception Of Ecological Risk To Water Environments And How It Affects Water Consumption And Water Resource Management In Southern Nevada, Tanju Kiriscioglu
UNLV Theses, Dissertations, Professional Papers, and Capstones
Climate is harsh in southern Nevada where there is (and has been) a drought alert in effect for over a decade now (Kerr, 2007; Southern Nevada Water Authority, 2009). Las Vegas Valley is a major center of population in the region (1.9 million people), receiving only 4.5 inches of average annual precipitation yet in need of securing more water resources in the near future (SNWA, 2009). Water resource management in southern Nevada is a challenge, especially when 90% of the area’s water needs are met by a single source, the Colorado River, the flow rates of which have been in …
The Integration Of Biomimicry Into A Built Environment Design Process Model: An Alternative Approach Towards Hydro-Infrastructure, Timothy Lee Albertson
The Integration Of Biomimicry Into A Built Environment Design Process Model: An Alternative Approach Towards Hydro-Infrastructure, Timothy Lee Albertson
UNLV Theses, Dissertations, Professional Papers, and Capstones
Current methods and processes that support the planning, design and construction of a sustainable built environment include ambiguous principles (Roseland 2000), lack feedback loops (Van Bueren and Jong 2007) and lack a common language between disciplines (Brandon et al 1997). As a result of 3.8 billion years of "research and development" (evolution), nature provides a set of design blueprints that may be used to guide us to create elegant, sustainable, and innovative designs for human technologies (Benyus 1997). The field of biomimicry analyzes nature's best ideas and adapts them for human use (Benyus 1997). The built environment could benefit from …

A Coastal resort named Fiesta Surf is being planned for the southern portion of the Baja peninsula on the Pacific coast between the resort town of Cabo San Lucas and Todos Santos. Two additional resorts and an exclusive housing community are in the planning stages within this region, known as the "Pacific Corridor." The proposal for development is in a high growth region near the southern tip of the Baja peninsula in the state of Baja California, Sur, Mexico. The Pacific coast of southern Baja has seen little development and consists largely of non-developed shoreline. The current economic base of …
Water Conservation In The Las Vegas Valley, Judith M. Keir
Water Conservation In The Las Vegas Valley, Judith M. Keir
UNLV Theses, Dissertations, Professional Papers, and Capstones
This thesis deals primarily with residential use of water in the Las Vegas Valley, an arid climate located in the Mojave Desert, and whether the education of people living here has any bearing on whether or not they conserve water. Many of the residents of the Las Vegas Valley have moved from other areas of the country, and perhaps are not aware of the fact that there is a limited supply of water available to the Valley. I believe that people are not necessarily wasteful, and that they would want to conserve water, if they were aware that conservation and …
Updating The Colorado River Compact, Jeffrey A. Freer
Updating The Colorado River Compact, Jeffrey A. Freer
UNLV Theses, Dissertations, Professional Papers, and Capstones
Water is essential to life in the arid environment of the western United States. For centuries, humans have used the Colorado River to fulfill their needs and until the past 100 years, the use of the river was sustainable. Over the last 100 years, the Colorado River has been dammed and diverted to "reclaim" the arid west for man's use. In 1946, a Department of the Interior report stated that "Tomorrow the Colorado will be utilized to the very last drop. Its water will convert thousands of additional acres of sagebrush desert to flourishing farms and beautiful homes for servicemen, …
