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 …
Reno, Nevada Imazapic Ecological Risk Assessment: Final Report, Ensr International, Bureau Of Land Management
Reno, Nevada Imazapic Ecological Risk Assessment: Final Report, Ensr International, Bureau Of Land Management
All U.S. Government Documents (Utah Regional Depository)
The Bureau of Land Management (BLM), United States Department of the Interior (USDI), is proposing a program to treat vegetation on up to six million acres of public lands annually in 17 western states in the continental United States (U.S.) and Alaska. The primary objectives of the proposed program include fuels management, weed control, and fish and wildlife habitat restoration. Vegetation would be managed using five primary vegetation treatment methods: mechanical, manual, biological, chemical, and prescribed fire. The BLM and its contractor, ENSR, are preparing a Vegetation Treatments Programmatic Environmental Impact Statement (EIS) to evaluate the effects of the proposed …

The Bureau of Land Management (BLM), United States Department of the Interior (USDI), is proposing a program to treat vegetation on up to six million acres of public lands annually in 17 western states in the continental United States (U.S.) and Alaska. As part of this program, the BLM is proposing the use of ten herbicide active ingredients (a.i.) to control invasive plants and noxious weeds on approximately one million of the 6 million acres proposed for treatment. The BLM and its contractor, ENSR, are preparing a Vegetation Treatments Programmatic Environmental Impact Statement (EIS) to evaluate this and other proposed …

Valuing Wildfire Risk Mitigation In Kyle Canyon, Nevada, James P. O'Brien
Valuing Wildfire Risk Mitigation In Kyle Canyon, Nevada, James P. O'Brien
UNLV Theses, Dissertations, Professional Papers, and Capstones
The federal government lists Kyle Canyon, Nevada, as an at-risk wildland-urban interface community. Stakeholders' attitudes and preferences about wildfires and mitigation options were assessed through a survey. 541 surveys were sent and 107 returned. More than a majority of stakeholders report the chances of wildfire occurrence as very likely. Stakeholders demonstrate consensus in reporting high concern about wildfire potential for Kyle Canyon, Nevada. Fire fighters assign the greatest responsibility for mitigating wildfire risks to Clark County, Nevada, and the federal government, while resident property owners do not assign responsibility consistently to any particular group. Trimming is the most favored mitigation …

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.
Total Suspended Solids In Las Vegas Wash, Mika Koponen
Total Suspended Solids In Las Vegas Wash, Mika Koponen
UNLV Theses, Dissertations, Professional Papers, and Capstones
Erosion along the Las Vegas Wash (Wash) has increased steadily along with the rapidly increasing population. The focus of this study is to find out if there is a relationship between lower total suspended solids rate (TSS) and the construction of erosion control structures along the Wash. The study was conducted between 7/15/2003 and 11/29/2004.
The method was water sampling on 7 sites and the samples were analyzed at Southern Nevada Water Systems (SNWS) laboratory at Saddle Island in Boulder City. Additional water quality data was also collected using Quanta, a device measuring different parameters in water. In this study …

A Comparison Of Population Sizes And Number Of Captures For The Desert Woodrat (Neotoma Lepida) In Two Microhabitats In The Las Vegas Wash, Nevada, Jayson Barangan
UNLV Theses, Dissertations, Professional Papers, and Capstones
Planned removal and eradication of saltcedar in the Las Vegas Wash, Nevada could potentially generate adverse impacts on present desert woodrat (Neotoma lepida) populations inhabiting the area. Consequently, research was conducted investigating population sizes of N. lepida in two distinct microhabitat types, saltcedar (Tamarix sp.) and mesquite/quailbush (Prosopis sp./Atriplex lentiformis). The results of this study will aid in gauging the effects of the changes in vegetation once restoration work is completed and assist with logistical scheduling for implementation of control measures. Mark-recapture field techniques were utilized for data collection from July 2002 to June 2003. Population estimates were calculated using …

Observed Omnivory In The Herbivorous Blue Tilapia (Oreochromis Aureus), Stephen M. Oliveira Jr.
UNLV Theses, Dissertations, Professional Papers, and Capstones
Gila seminuda, a native endangered species, and Oreochromis aureus, a nonnative invasive species, share the same habitat in the form of the Reid Gardner Power Plant intake ponds. The purpose of this study is to characterize the feeding habits of Oreochromis aureus within the Reid Gardner Power Plant intake ponds and address the potential predation habits of Oreochromis aureus. Stomach contents of O. aureus were identified and analyzed using chi-square and log-likelihood ratio techniques, with respect to mass, length, girth, gender, or spatial distribution of samples. Results showed omnivorous behavior with a 7.00% predatory/prey relationship, and no difference of feeding …
