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 …
The Environmental And Economic Benefits Of Highway Access Management: A Multivariate Analysis Using System Dynamics, Dan Andersen
The Environmental And Economic Benefits Of Highway Access Management: A Multivariate Analysis Using System Dynamics, Dan Andersen
UNLV Theses, Dissertations, Professional Papers, and Capstones
Better management of highway operations can be achieved, in part, by controlling vehicular access to adjacent properties and cross streets. This tactic, referred to as access management, has proven safety and operational benefits. However, doubts remain regarding its environmental and economic benefits.
I hypothesize that one environmental indicator, carbon emissions, will decrease with proper access management. Controlling access increases the speed at which vehicles travel, improving fuel efficiency and reducing carbon emissions. My hypothesis relative to financial impacts is that access management will neither help nor harm businesses. Controlling access can reduce travel time which has the effect of increasing …
Assessing The Relationships Between The Spatial Variation In Land-Use Spatial Patterns And Surface Water Quality, Majed A. Khater
Assessing The Relationships Between The Spatial Variation In Land-Use Spatial Patterns And Surface Water Quality, Majed A. Khater
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this dissertation was to examine the association between the spatial patterns of urban land uses and surface water quality parameters at the watershed outlet. The aim of the study was to understand the strength and nature of this relationship, and examine new methods of classifying and quantifying contributing urban land-uses and their spatial patterns. The hypothesis of this research was: in an urban watershed, the variation in the spatial patterns of contributing land uses will have a significant impact on the surface water quality parameters at the watershed outlet.
This relationship between urbanization and water quality is …
Using A Systems Dynamics Approach To Determine What Can Be Done To Minimize Ozone Production, Jusdi Mcdonald
Using A Systems Dynamics Approach To Determine What Can Be Done To Minimize Ozone Production, Jusdi Mcdonald
UNLV Theses, Dissertations, Professional Papers, and Capstones
Ground level ozone is an air pollutant that affects people of all ages and origins in many urban areas including the Las Vegas Valley. The purpose of this study is to examine the best strategy to minimize tropospheric ozone generation through using a system dynamics approach via LUTAQ is used to formulate a solution to the reduction of ozone in the Clark County non-attainment area. By increasing housing density, decreasing average distance per trip, and decrease average number of trips per person per day is the most effective strategies to improving ozone levels in Las Vegas Valley.
Defining Soil Type And Habitat Characteristics Of The Arctomecon Californica, Philip S. Childers
Defining Soil Type And Habitat Characteristics Of The Arctomecon Californica, Philip S. Childers
UNLV Theses, Dissertations, Professional Papers, and Capstones
A. californica can be considered a rare endemic species, which is believed to be restricted by unique soil relationships. These relationships make the species vulnerable to anthropogenic habitat disturbance. Although A. californica is listed as critically endangered by the state of Nevada, further research is needed before the species can be listed as federally endangered or threatened. This study used primary observational data and secondary GIS compatible data to characterize A. californica habitat. Representative sampling techniques were used to select observations from derived soil types. Although a majority of A. californica populations were found to occur in gypsic soil types, …
Consumptive Water Use At The Mirage Hotel And The Mandalay Bay Resort & Casino In Las Vegas, Nevada, Johann A. Feller
Consumptive Water Use At The Mirage Hotel And The Mandalay Bay Resort & Casino In Las Vegas, Nevada, Johann A. Feller
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Las Vegas Valley is one of the driest regions in the southwest United States. Due to limited water supplies from the Colorado River, rainfall, and groundwater sources, the water requirements of the valley’s growing population is slated to surpass the current available water supply. The purpose of this comparative study is to quantify the amount of consumptive water used at a major Las Vegas resort/casino in one year. This, being of importance, because of the resort/casino industry’s role as one of the largest, most visible, and most resource intensive industries in the Las Vegas valley. The goal of this …
Systemic Environmental Analysis Of The Legal Mechanisms For Controlling Air Pollution In The Las Vegas Valley, Richard Little
Systemic Environmental Analysis Of The Legal Mechanisms For Controlling Air Pollution In The Las Vegas Valley, Richard Little
UNLV Theses, Dissertations, Professional Papers, and Capstones
This study examines the air pollution control structure for the Las Vegas Valley. A System Dynamics computer model was created that represents the structure of the real world system for controlling air pollution, in order to examine how the current air pollution control system might behave in the future.
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 …
The Price Of Clean Air: A Consideration Of Market Based Emissions Trading, Mark W. Miller
The Price Of Clean Air: A Consideration Of Market Based Emissions Trading, Mark W. Miller
UNLV Theses, Dissertations, Professional Papers, and Capstones
Traditional regulatory approaches for environmental protection do not consider
the costs and benefits of the standards they impose. Further, imposing strict performance
standards on firms with heterogeneous control costs leads to an inefficient allocation of resources devoted to pollution control. This paper explores the use of emission allowance trading as a way to improve economic efficiency within the context of environmental protection. PM10 air pollution from sources within the Las Vegas Valley is used as the case study.
This paper found that an emission trading
program in this particular case study would not live up to the theoretical expectations. Although, …
