Los Problemas Energéticos De Chile Y Sus Soluciones: El Rol De Las Energías Renovables No Convencionales, Megha Jain

Independent Study Project (ISP) Collection

Esta investigación trata sobe la seguridad energética de Chile, un concepto relativamente nuevo que tiene que ver con la capacidad de un país para garantizar un suministro energético, que permita el crecimiento económico y el desarrollo social. Actualmente, Chile se encuentra en una posición energética muy vulnerable. A pesar de su riqueza geográfica repleta de recursos energéticos renovables, carece de las fuentes de energía más importantes hoy día: el petróleo, el carbón y el gas natural. Por eso, para cumplir con una demanda creciente, tiene que importar entre el 70%  y el 80% de su energía, dependiendo de pocos suministradores …

Environmental Disturbance Of Oligotrophic Bacteria And Effects On Water Quality In Deep Karstic Pools, Andrea Hunter

Water Resources Professional Project Reports

Active intervention of humans in pristine water resource environments has caused both surface and ground waters to degrade in quality and natural purification capacity (Geldreich 1996). Groundwater is often considered to be less impacted than that of surface water due to the absence of climate changes and storm water migrations (Geldreich 1996). Shallow karstic limestone areas (less than 30 m deep) have a greater change of surface contamination since surface water runoff can rapidly percolate through areas lacking a protective bedrock layer.

Geochemical Analysis Of Surface And Ground Waters Around Cle Elum, Wa; Implications For The Proposed Exempt Well Moratorium, David Hickey, Ryan Opitz, Carey A. Gazis

Student Published Works

The Yakima River drainage is one of the most heavily irrigated regions in the state, and water use has been much contested and litigated. Due to this water demand and the increase in drilling of domestic wells, a moratorium on exempt well drilling was proposed in 2007. In this study geochemical data is used to evaluate the surface-groundwater interaction in the area around Cle Elum, WA. The hydrogeology of this area is poorly understood due to the complex stratigraphy where the valley floor meets the bedrock of the Cascade Range. It is important to understand the relationship between groundwater and …

Construction Cost Models, Barry Dikeman

Economics and Finance

The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …

Hydrogeomorphic Segments And Hydraulic Microhabitats Of The Niobrara River, Nebraska, With Special Emphasis On The Niobrara National Scenic River, Jason S. Alexander, Ronald B. Zelt, Nathaniel J. Schaepe

United States Geological Survey: Water Reports and Publications

The Niobrara River is an ecologically and economically important resource in Nebraska. The Nebraska Department of Natural Resources’ recent designation of the hydraulically connected surface- and groundwater resources of the Niobrara River Basin as “fully appropriated” has emphasized the importance of understanding linkages between the physical and ecological dynamics of the Niobrara River so it can be sustainably managed. In cooperation with the Nebraska Game and Parks Commission, the United States Geological Survey USGS) investigated the hydrogeomorphic and hydraulic attributes of the Niobrara River in northern Nebraska. This report presents the results of an analysis of hydrogeomorphic segments and hydraulic …

Temporal And Spatial Assessment Of Evaporation, Transpiration, And Soil Moisture Redistribution, Brian M. Bird

UNLV Theses, Dissertations, Professional Papers, and Capstones

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 …

Identification Of Geochemical Facies Through Major Ion Data And Additional Parameters From Shallow Groundwater Utilizing A Comparison Of Geomathematics And Traditional Methods In Las Vegas Valley, Nevada, Eric Dano

UNLV Theses, Dissertations, Professional Papers, and Capstones

There has been little exploration to identify geochemical facies in shallow groundwater in the Las Vegas Valley in Clark County, Nevada. Identification of hydrochemical facies in Las Vegas Valley is important for assessing the extent and nature of a potential groundwater resource. The identification of facies could be complicated by the possibility that secondary recharge constitutes a hydrochemical facies of its own. To identify geochemical facies, groundwater samples for major ions, stable isotopes and some municipal tracers were collected from 35 wells in an established network of monitor wells. Wells were purged with a bailer or 12V pump and EC, …

Evaluating The Impacts Of Water Conservation Policies On Water Demand, Availability And Outdoor Water Use In The Las Vegas Valley, Kamal Qaiser

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Las Vegas Valley, located in the arid Southern Nevada region, with a growing population, limited water resources, and a prolonged drought, faces a challenge in meeting its future water needs. Southern Nevada Water Authority (SNWA), the main water management agency in the Valley, is focusing on water conservation to reduce water demand. Current water use is 945 lpcd (250 gpcd) which SNWA aims to reduce to 752 lpcd (199 gpcd) by 2035. Presently the indoor outdoor water use proportion is about 40:60 in the Valley. An important component of the Valley's supply are the return flow credits which SNWA …

Investigation Of Potential Pathways And Multi-Cycle Bioregeneration Of Ion-Exchange Resin Laden With Perchlorate, Mohamadali Sharbatmaleki

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ion-exchange (IX) is possibly the most feasible technology for perchlorate removal and perchlorate-selective and non-selective IX resins are commercially available for this purpose. The use of both resins has shortcomings. Selective resins are incinerated after one time use, and non-selective resins produce a regenerant waste stream that contains high concentration of perchlorate. A process involving directly contacting of spent IX resin containing perchlorate with perchlorate-reducing bacteria (PRB) to bioregenerate the resin has been developed and proven recently. In this process PRB biodegrade perchlorate ions which are attached to the functional groups of the resin.

Although its feasibility has been proven, …

Analytical Solutions For Efficient Interpretation Of Single-Well Push-Pull Tracer Tests, Junqi Huang, John A. Christ, Mark N. Goltz

Faculty Publications

Single-well push-pull tracer tests have been used to characterize the extent, fate, and transport of subsurface contamination. Analytical solutions provide one alternative for interpreting test results. In this work, an exact analytical solution to two-dimensional equations describing the governing processes acting on a dissolved compound during a modified push-pull test (advection, longitudinal and transverse dispersion, first-order decay, and rate-limited sorption/partitioning in steady, divergent, and convergent flow fields) is developed. The coupling of this solution with inverse modeling to estimate aquifer parameters provides an efficient methodology for subsurface characterization. Synthetic data for single-well push-pull tests are employed to demonstrate the utility …

A Life Cycle Cost Analysis Of Large-Scale Thermal Energy Storage Technologies For Buildings Using Combined Heat And Power, Kenneth Gaine, Aidan Duffy

Conference Papers

Buildings account for approximately 40% of energy consumption and greenhouse gas (GHG) emissions in developed economies, of which approximately 55% of building energy is used for heating and cooling. The reduction of building-related GHG emissions is a high international policy priority. For this reason and because there are many technical solutions for this, these polices should involve significant improvements in the uptake of small-scale energy efficient (EE) systems. However the widespread deployment of many technologies, must overcome a number of barriers, one of which is a temporal (diurnal or seasonal) mismatch between supply and demand. Costeffective thermal storage solutions have …

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 …
