Effect Of Spatial And Temporal Variability Of Antecedent Moisture Content On Model-Generated Runoff From An Arid Watershed, William J. Meyer
Effect Of Spatial And Temporal Variability Of Antecedent Moisture Content On Model-Generated Runoff From An Arid Watershed, William J. Meyer

Streams in the arid southwest are typically ephemeral, and stream gages are not commonly available. Consequently, runoff data from storm events is not available, and flood control facility design or other water resource related decisions are based on synthetic hydrographs. In the Mojave Desert region of Southern Nevada, the duration of storm used to develop these synthetic hydrographs is the 6 hour storm. The 6 hour storm is used to simulate high intensity summer storms. Additionally, soils information used in the calculations for these synthetic hydrographs is taken from maps that are generally developed for a broad range of issues …

At a native stand of creosote bush (Larrea tridentata) in North Las Vegas, a rainfall simulation study was conducted over a 12 month period from October 2005 to October 2006. Simulated rainfall occurred during the winter, spring, summer, and fall periods. Rainfall simulation systems were positioned on each of 12 plots, each containing a single creosote bush. Simulated rainfall events occurred at night with multiple short pulses designed to maximize infiltration while minimizing ponding. Yearly simulated rainfall amounts were set at 0, 15, 30 and 60 cm (replicated three times) and were approximately 0, 1.5, 3.0 and 6.0 times the …

Though Americans tend to view wilderness as separate from nature, environmental historians have argued that wilderness is a cultural construct more than a quantifiable geographic category. Red Rock Canyon National Conservation Area (NCA), a 195,000-acre tract located west of Las Vegas, Nevada, is one such cultural construction. Since 1960, this BLM-managed parcel has served as a local and regional expression of broader, national trends in outdoor recreation, interpretation, and development and thereby forced visitors to engage (often unknowingly) in a cultural dialogue about consumerism, technology, and identity. With information from newspapers, archival collections, oral histories, and government documents, this thesis …
Filtration And Growth Rate Of Lake Mead Quagga Mussels (Dreissena Bugensis) In Laboratory Studies And Analyses Of Bioaccumulation, Carolyn Louise Link
Filtration And Growth Rate Of Lake Mead Quagga Mussels (Dreissena Bugensis) In Laboratory Studies And Analyses Of Bioaccumulation, Carolyn Louise Link

In January of 2007, Quagga Mussels (Dreissena bugensis) were identified in Lake Mead, Nevada. An aquatic invasive species, these mussels can significantly alter ecosystems. This study sought to quantify three ecological traits of the species through a series of laboratory experiments and analyses, providing information both for comparison with Dreissena in other locations, as well as for limnologic management decisions. Filtration rate of quagga mussels was quantified using algal strains and natural seston. Two strains of green algae, Nannochloris and Scenedesmus were used to determine mussel filtration rates with a spectrophotometer. Quagga filtration rates of collected Lake Mead seston were …
