Simulation Of Groundwater Flow And Effects Of Groundwater Irrigation On Stream Base Flow In The Elkhorn And Loup River Basins, Nebraska, 1895-2055: Phase Two, Jennifer S. Stanton, Steven M. Peterson, Michael N. Fienen

United States Geological Survey: Water Reports and Publications

Regional groundwater-flow simulations for a 30,000-square-mile area of the High Plains aquifer, referred to collectively as the Elkhorn-Loup Model, were developed to predict the effects of groundwater irrigation on stream base flow in the Elkhorn and Loup River Basins, Nebraska. Simulations described the stream-aquifer system from predevelopment through 2005 [including predevelopment (pre-1895), early development (1895–1940), and historical development (1940 through 2005) conditions] and future hypothetical development conditions (2006 through 2033 or 2055). Predicted changes to stream base flow that resulted from simulated changes to groundwater irrigation will aid development of long-term strategies for management of hydrologically connected water supplies.

As Rivers Run Dry: A Study Of Global Freshwater Scarcity And Its Implications For Socio-Economic Development, Sophia Wenzlau

Independent Study Project (ISP) Collection

Water scarcity is a serious problem—without adequate supplies of clean freshwater, there cannot be life. The direct and indirect costs of water scarcity are huge, including poor public health, gender inequality, and acute restrictions for economic development. Currently, around 20 percent of the global population lacks access to safe drinking water and 2.4 billion people do not have access to adequate sanitation facilities (UNEP Brief, 1). About 1.8 million people—most of them children less than five years old—die every year due to water-borne diseases from fecal pollution—the equivalent of about 15 killer tsunamis each year or 12 Boeing 747 crashes …

“Mieux Vaut Prévenir Que Guérir”: The Effect Of Natural Disasters On Water- And Sanitation-Related Infectious Diseases And The Increasing Need For Disaster Preparedness, Naomi Malam

Independent Study Project (ISP) Collection

The world is suffering from an extreme global water crisis. 1.1 billion people in the world lack access to adequate clean water, and 2.6 billion people lack access to water and sanitation. Approximately 10 million deaths per year can be attributed to this water crisis; water-borne infectious diseases play a significant role in this death toll. Diarrhoeal disease accounts for 2.6 million deaths per year and is one of the leading causes of death in many developing countries.

We are entering a period of undeniable climate change which is bringing about more natural disasters and extreme weather events than ever …

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 …

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 …

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, …

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 …
