Performance-Based Management To Improve Water Quality, John Rodecap, Chad Ingels Dec 2005

Performance-Based Management To Improve Water Quality, John Rodecap, Chad Ingels

Proceedings of the Integrated Crop Management Conference

In recent years water quality assessments and the science of water quality management have progressed much more rapidly than delivery of this information and implementation of strategies for performance-based water quality improvement. Nonpoint source water quality improvements and solutions on the broad landscape need new approaches that lead to a majority of producers in a watershed community working to manage nonpoint source contaminants and jointly developing locally acceptable environmental stewardship goals.


A Unified Model For Subaqueous Bed Form Dynamics, Douglas J. Jerolmack, David Mohrig Dec 2005

A Unified Model For Subaqueous Bed Form Dynamics, Douglas J. Jerolmack, David Mohrig

Departmental Papers (EES)

Bed form evolution remains dynamic even in the special case of steady, uniform flow. Data from the sandy, braided North Loup River, Nebraska, show that roughness features on the channel bottom display a statistical steady state and robust scaling that are maintained through the collective interactions of transient (short-lived) bed forms. Motivated by such field data, and laboratory observations of bed form growth, we develop a nonlinear stochastic surface evolution model for the topography of bed load dominated sandy rivers in which instantaneous sediment flux explicitly depends on local elevation and slope. This model quantitatively reproduces laboratory observations of initial ...


Assessing The Relationships Between The Spatial Variation In Land-Use Spatial Patterns And Surface Water Quality, Majed A. Khater Dec 2005

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 ...


Coupled Oceanic-Atmospheric Variability And U.S. Streamflow, Glenn A. Tootle, Thomas C. Piechota, Ashok Singh Dec 2005

Coupled Oceanic-Atmospheric Variability And U.S. Streamflow, Glenn A. Tootle, Thomas C. Piechota, Ashok Singh

Civil & Environmental Engineering and Construction Faculty Publications

A study of the influence of interdecadal, decadal, and interannual oceanic-atmospheric influences on streamflow in the United States is presented. Unimpaired streamflow was identified for 639 stations in the United States for the period 1951–2002. The phases (cold/negative or warm/positive) of Pacific Ocean (El Niño–Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO)) and Atlantic Ocean (Atlantic Multidecadal Oscillation (AMO) and North Atlantic Oscillation (NAO)) oceanic-atmospheric influences were identified for the year prior to the streamflow year (i.e., long lead time). Statistical significance testing of streamflow, based on the interdecadal, decadal, and interannual oceanic-atmospheric phase (warm ...


Removal Of Heavy Metals From Aqueous Solutions Using Local Adsorbents, Moza S. Al-Sharyani Dec 2005

Removal Of Heavy Metals From Aqueous Solutions Using Local Adsorbents, Moza S. Al-Sharyani

Theses

The recent rapid increase in industrialization activities contributed to most of aquatic pollution problems. Among aquatic pollutants, heavy metals, such as zinc, lead, cadmium, and copper have gained relatively more significance in view of their persistence and toxicity. Due to their health and toxicological effects, environmental agencies and authorities have set strict regulations to maintain the limit of heavy metals in wastewater below the maximum acceptable concentration levels.

The technical feasibility of using raw date pits and different activated carbons prepared from date pits by air and acid activation as low cost local adsorbents for the removal of different heavy ...


Establishing Conservation Buffers Using Precision Information, Michael G. Dosskey, Dean E. Eisenhauer, Matthew J. Helmers Nov 2005

Establishing Conservation Buffers Using Precision Information, Michael G. Dosskey, Dean E. Eisenhauer, Matthew J. Helmers

Agricultural and Biosystems Engineering Publications

Conservation buffers, such as filter strips and riparian forest buffers, are widely prescribed to improve and protect water quality in agricultural landscapes. These buffers intercept field runoff and retain some of its pollutant load before it reaches a waterway. A buffer typically is designed to have uniform width along a field margin and to intercept runoff that flows uniformly to it. However, spatial analysis of field conditions and runoff patterns indicate that more runoff is likely to flow to some locations along a field margin than to others which can substantially limit a buffer's effectiveness. We propose that precision ...

Tunnel Geology As Seen By Geologists: Manhattan, New York City, Nazrul I. Khandaker, Stanley Schleifer, Masud Ahmed, Alan R. Slaughter, Belal A. Sayeed, Dorean J. Flores, Mario Jo-Ramirez

Publications and Research

Current exploratory boring operations in and around Manhattan, New York City are providing geologists and geotechnical engineers with a plethora of new and interesting geological information, which has not been previously reported. The rocks encountered, mostly medium to high-grade metamorphic rocks, with both mafic and felsic intrusives, are highly variable in competency and mechanical durability. One of the most frequently encountered rock types is a garnetiferous-muscovite-biotite schist which grades into schistose gneiss and displays a wide variety of structural, compositional, and textural attributes. Metamorphic minerals showing the variable degree of metamorphism include graphite, talc, garnet, kyanite, tourmaline, emory, and occasionally ...

Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer Oct 2005

Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum length of fishes captured with angling. Although significant (based on sequential Bonferroni adjustment) correlation was found in only one of nine sport fishes assessed, all correlations were positive indicating a general trend between maximum size of fishes captured with ...

Hydrological Cycle In The Upper Mississippi River Basin: 20th Century Simulations By Multiple Gcms, Eugene S. Takle, Manoj Jha, Christopher J. Anderson Sep 2005

Hydrological Cycle In The Upper Mississippi River Basin: 20th Century Simulations By Multiple Gcms, Eugene S. Takle, Manoj Jha, Christopher J. Anderson

Geological and Atmospheric Sciences Publications

We used 20th century simulations by nine global climate models (GCMs) to provide input for a streamflow model to simulate baseline hydrologic conditions in the Upper Mississippi River Basin (UMRB). Statistical tests revealed that streamflow data produced by members of the GCM multi-model ensemble were serially uncorrelated at all lags and formed unimodal distributions and that GCM multi-model results may be used to assess annual streamflow in the UMRB. Although all low-resolution GCMs produced large differences from observations of streamflow and hydrological components simulated by the streamflow model, the nine-member ensemble performed quite well. Results of statistical tests indicate that ...

Final Report: Evaluation Of The Morphoedaphic Index And Sediment Diatoms For Inference Of Pre-European Settlement Total Phosphorus Concentration In Epa Region 10 Lakes, Rich Miller, Aaron Hook, Richard Petersen, Mark D. Sytsma Sep 2005

Final Report: Evaluation Of The Morphoedaphic Index And Sediment Diatoms For Inference Of Pre-European Settlement Total Phosphorus Concentration In Epa Region 10 Lakes, Rich Miller, Aaron Hook, Richard Petersen, Mark D. Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Water quality in many Northwest lakes has declined over the past century due, in part, to increased anthropogenic nutrient loading (Edmonson and Lehman, 1981). Under the Clean Water Act, resource managers such as the Washington Department of Ecology, Oregon Department of Environmental Quality, and tribes are responsible for restoring and protecting the integrity of these waters. Targets for restoration or criteria for impairment are not well defined, however, and may naturally vary by geology, hydrology, morphometry, and climate.

One way to determine whether lakes are impaired and to identify restoration targets is to assess lake reference conditions (EPA 2000). Reference ...

Effects Of Liquid Swine Manure Applications On No3–N Leaching Losses To Subsurface Drainage Water From Loamy Soils In Iowa, Allah Bakhsh, Ramesh S. Kanwar, Douglas Karlen

Agricultural and Biosystems Engineering Publications

Long-term applications of organic or inorganic sources of N to croplands can increase the leaching potential of nitrate–nitrogen (NO3–N) for soils underlain by subsurface drainage “tile” network. A field study was conducted for 6 years (1993–1998) to determine the effects of liquid swine manure and urea ammonium nitrate (UAN) solution fertilizer applications on NO3–N concentrations and NO3–N losses with subsurface drainage water under continuous corn (Zea maize L.) and corn after soybean (Glycine max. L.) production systems. The field data collected at Iowa State University's northeastern research center near Nashua, Iowa ...


Potential Impacts Of Climate Change On Agricultural Land Use Suitability : Wheat, Dennis Van Gool, Luke Vernon Aug 2005

Potential Impacts Of Climate Change On Agricultural Land Use Suitability : Wheat, Dennis Van Gool, Luke Vernon

Resource management technical reports

This publication considers the impact of climate change on wheat crops. While a model was first used, it was only partially validated against real data, hence the model is now used as a decision support system that allows people with crop, land resource and climate knowledge to determine potential impacts of climate change on crop growth and production in Western Australia.

Lake Whatcom Water Quality Model, Chris Berger

Civil and Environmental Engineering Faculty Publications and Presentations

A water quality model of Lake Whatcom, Washington was developed as part of a Total Maximum Daily Load Study for the Washington Department of Ecology. Lake Whatcom is a large natural lake which is listed on the 1998 Washington State 303(d) list of waterbodies which do not meet the criterion for dissolved oxygen. Located next to the city of Bellingham, it is approximately 10 miles long and has a surface area of approximately 5000 acres and a maximum depth of over 100 meters. Eutrophication processes in the lake have been accelerated in recent years perhaps by the availability of ...
