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 …

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 …

Converting Turfgrass To Xeriscape: Evaluating Southern Nevada Water Authority’S “Water Smart Program”, Tom Hudak

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study evaluated the use and effectiveness of the Xeriscape Conversion program, dubbed the “Water Smart Program,” administered by the Southern Nevada Water Authority. The Conversion program is used by five water purveyors throughout Southern Nevada. Because of phenomenal growth in the area, water has become one of the most valuable resources. With its limited availability, conservation has become the logical solution to ever increasing demand. Using empirical data, effectiveness of the program was evaluated in areas such as: water savings after xeriscape conversion; maintenance savings after conversion; the influence of system design on water consumption; and the long term …
