Modeling Dissolved Oxygen In Lake Powell Using Ce-Qual-W2, Nicholas Trevor Williams Mar 2007

Modeling Dissolved Oxygen In Lake Powell Using Ce-Qual-W2, Nicholas Trevor Williams

Theses and Dissertations

Water quality models in the Colorado River Basin have been developed for the basin, river, and individual reservoirs. They are used to support water quality programs within the basin. The models are periodically reviewed and updated to improve the accuracy of simulations. Improving the usefulness of the Lake Powell model, one of the key reservoirs in the basin, is the subject of this study. Lake Powell is simulated using a hydrodynamic and water quality model, CE-QUAL-W2. Previously the model has been used at Lake Powell to simulate hydrodynamics, temperature, and total dissolved solids with a reasonable degree of accuracy. An …

Spatial Variability And Prediction Modeling Of Groundwater Arsenic Distributions In The Shallowest Alluvial Aquifers In Bangladesh Jan 2007

Spatial Variability And Prediction Modeling Of Groundwater Arsenic Distributions In The Shallowest Alluvial Aquifers In Bangladesh

Journal of Spatial Hydrology

Elevated arsenic in groundwater is the greatest environmental problem in Bangladesh. Spatial variability of arsenic in groundwater has been examined by semivariogram analysis that revealed high degree of small-scale spatial variability in alluvial aquifers. Small-scale variability of arsenic concentrations, indicated by high “nugget” values in semivariograms, is associated with heterogeneity in local-scale geology and geochemical processes. In unsampled locations, arsenic concentrations have been predicted using both deterministic and stochastic prediction methods. Natural neighbor (NN) method predicted better than inverse distance to power (IDP) method, and small-scale variations of arsenic concentrations are preserved. Ordinary kriging (OK) method on the untransformed arsenic …

Plant Composition And Erosion Potential Of A Grazed Wetland In The Salmon River Subbasin, Idaho, Kristine N. Hopfensperger, Joan Q. Wu, Richard A. Gill Aug 2006

Plant Composition And Erosion Potential Of A Grazed Wetland In The Salmon River Subbasin, Idaho, Kristine N. Hopfensperger, Joan Q. Wu, Richard A. Gill

Western North American Naturalist

Wetlands are dynamic habitats with many unique, important functions including filtering sediments and providing diverse habitats for fish and wildlife. Wetlands in the western United States are particularly important because they offer habitat for a number of protected runs of endangered fish species. Historically, livestock grazing has altered wetland and riparian area form and function by facilitating exotic species invasions, altering spatial heterogeneity of vegetation, and increasing erosion. In this study we examined vegetation structure and erosion potential in a wetland meadow exposed to unregulated grazing along Deer Creek in the Salmon River subbasin, Idaho. We characterized the vegetation composition …

The Brightening Light On The Journey Of Lehi And Sariah, Daniel B. Mckinlay Jul 2006

The Brightening Light On The Journey Of Lehi And Sariah, Daniel B. Mckinlay

Journal of Book of Mormon Studies

Until now, nearly all commentaries on the Book of Mormon have focused mainly on issues of doctrine rather than beginning with the text itself. Royal Skousen’s critical text project does the opposite by treating the text itself on the word and phrase level. Skousen weighs nearly all possible evidence to deduce the events that may have led to the variations seen in the texts and to draw conclusions about which readings are most likely original. Some conclusions may surprise readers, but Skousen is more interested in candidly documenting what the texts reveal than in interpreting all the implications. Several lengthy …

Birds Along Lehi's Trail, Stephen L. Carr Jul 2006

Birds Along Lehi's Trail, Stephen L. Carr

Journal of Book of Mormon Studies

Royal Skousen’s work on his Book of Mormon critical text project demonstrates that he is an able textual critic who employs sound judgment and proven methods to uncover the original text of the Book of Mormon. In many cases, these decisions seem counterintuitive to untrained readers, but Skousen correctly applies the principle that a more awkward reading is most likely original. He also shows his ability to make conjectural emendations for which no direct textual evidence is available. In every case, Skousen clearly lays out his reasoning so that readers who disagree with his inferences can examine the evidence for …

An Awakened Sense Of Place: Thoreauvian Patterns In Willa Cather's Fiction, Breanne Grover Jul 2006

An Awakened Sense Of Place: Thoreauvian Patterns In Willa Cather's Fiction, Breanne Grover

Theses and Dissertations

The recent "greening" of Willa Cather Scholarship has initiated new conversations about Cather's use of and dependence on landscape in her fiction. Scholars have frequently noted Cather's reliance on landscape imagery, but this thesis suggests parallels between Cather's and Henry David Thoreau's use of awakening imagery and examines how such parallels work in Cather's environmental discussion of wilderness and environmental communities. There is little direct evidence linking the development of Cather to Thoreau, although their similar use of awakening imagery suggests they comment on similar environmental discussions through their writing, indicating that Cather deserves further attention as a nature writer. …

The Use Of Inductive And Deductive Reasoning To Model Snowmelt Runoff From Northern Mountain Catchments, P. F. Dornes, J. W. Pomeroy, A. Pietroniro, S. K. Careyc, W. L. Quinton Jul 2006

The Use Of Inductive And Deductive Reasoning To Model Snowmelt Runoff From Northern Mountain Catchments, P. F. Dornes, J. W. Pomeroy, A. Pietroniro, S. K. Careyc, W. L. Quinton

International Congress on Environmental Modelling and Software

Reliable hydrological modeling at small to medium scales is very difficult. At these scale, models require incorporation of both detailed process understanding and inputs along with information gained from observations of basin-wide streamflow phenomenon; essentially a combination of deductive and inductive approaches. At Granger Creek, part of the Wolf Creek Research Basin in the mountains of the Yukon Territory, Canada, sparse and shrub tundra cover the basin and soils are frozen at the time of snowmelt. Wind redistributes snow to north facing slopes and shrub tundra areas, while spring melt rates are much higher on south facing slopes due to …

International Congress on Environmental Modelling and Software

Current uncertainty in quantifying the global carbon budget remains a major contributing source of uncertainty in reliably projecting future climate change. Furthermore, quantifying the global carbon budget and characterizing uncertainties have emerged as critical to a successful implementation of United National Framework Convention on Climate Change and its Kyoto Protocol. Beyond fundamental quantification, attribution of the processes responsible for the so-called ‘residual terrestrial uptake’ is important to the carbon cycle communities’ ability to simulated the future response of the terrestrial biosphere to climate change and intentional sequestration activities. This paper’s objective is to describe the efforts of the workshop participants …

Air Pollution In Japan: The Inverted U-Shaped Relation, T. Fukiharu Jul 2006

Air Pollution In Japan: The Inverted U-Shaped Relation, T. Fukiharu

International Congress on Environmental Modelling and Software

In 1995 Grossman and Krueger, utilizing the data collected worldwide, discovered the invertedU-shaped relation between the per-capita GDP and air pollution level. It may be explained that the relationholds in each country. To explain the inverted U-shaped relation, however, an alternative explanation is alsopossible: although for each country's cross-sectional data the positive correlation holds between the percapitaGDP and pollution level, the worldwide data may exhibit the inverted U-shape. The worldwide resultmight be regarded as the one of time-series data, in which each country's preference relation towardsenvironment is different depending on the stage of economic growth. First, it is shown by …

Ten Iterative Steps In Development And Evaluation Of Environmental Models, A. J. Jakeman, R. A. Letcher, J. P. Norton Jul 2006

Ten Iterative Steps In Development And Evaluation Of Environmental Models, A. J. Jakeman, R. A. Letcher, J. P. Norton

International Congress on Environmental Modelling and Software

Models are increasingly being relied upon to inform and support natural resource management. They are incorporating an ever broader range of disciplines and now often confront people without strong quantitative or model-building backgrounds. These trends imply a need for wider awareness of what constitutes good model-development practice, including reporting of models to users and sceptical review of models by users. To this end the paper outlines ten basic steps of good, disciplined model practice. The aim is to develop purposeful, credible models from data and prior knowledge, in consort with end-users, with every stage open to critical review and revision. …

Predicting Impacts Of Water Management In Coastal Zones By Hydraulic And Salinity Modeling, C. T. Hoanh, N. D. Phong, J. W. Gowing, T. P. Tuong, N. X. Hien, N. D. Dat

International Congress on Environmental Modelling and Software

Tidal effects and salinity intrusion are two defining characteristics of coastal zones. The firstcauses complex variations of water level and unsteady flows in the river and canal network. The second is aconstraint to agriculture and freshwater fishery, but provides suitable conditions for brackish wateraquaculture. These phenomena bring about conflicts in the development of agriculture, fishery andaquaculture due to different requirements of water quality. Hydraulic and salinity modeling have beendeveloped and applied to simulate tidal propagation and salinity intrusion, and to analyze the effects of watermanagement on hydrological and salinity conditions that control land use in the coastal zones.

Modelling Of Water Pollution In Urban Areas With Gis And Multivariate Statistical Methods, L. Matejicek Jul 2006

Modelling Of Water Pollution In Urban Areas With Gis And Multivariate Statistical Methods, L. Matejicek

International Congress on Environmental Modelling and Software

Integrating modelling of water pollution and GIS enables the connection of environmental process models with geospatial data describing the physical environment. Time series of water pollution data at monitoring profiles are used to complement the spatial database and to interpret the results of data analysis. In this case, the multivariate statistical methods provide an exploratory environment for data analysis and an indication of seasonal changes in the framework of surface water pollution. In addition to a wide range of useful multivariate methods, principal component analysis (PCA) and factor analysis (FA) are used to differentiate seasonal water pollution at monitoring profiles. …

Spatial Estimations Of Air Pollution In Urban Areas By Lidar Measurements, L. Matejicek

International Congress on Environmental Modelling and Software

Spatial analysis and visualization of data focused on air pollution in urban areas can be more efficiently explored by geographic information systems (GISs). Data originating from direct monitoring, mathematical modelling and physical simulation in wind tunnels are represented by a wide range of data formats that, together with spatial objects on the surface of studied areas, form heterogenic structures. Thus, to solve spatio-temporal analysis and numeric models, a complex computer system is needed to manage the data and a number of user oriented procedures. In the case of this contribution, a GIS project is developed to examine the GIS abilities …

Features Of Advanced Decision Support Systems For Environmental Studies, Management, And Regulation, Edwin Roehl, Ruby Daamen, Paul A. Conrads

International Congress on Environmental Modelling and Software

Natural resource managers and users face difficult challenges when managing the interactions between natural and man-made systems. Even though the collective interests and computer skills of the community of managers, scientists, and other stakeholders are quite varied, there is an overarching need for equal access by all to the scientific knowledge needed to make the best possible decisions. A decision support system (DSS) can meet this need. DSS have been described as, “computer-based systems (for) helping decision-makers to solve various semi structured and unstructured problems involving multiple attributes, objectives, and goals… Historically, the majority of DSSs have been either computer …

Data Mining And Image Segmentation Approaches For Classifying Defoliation In Aerial Forest Imagery, K. Fukuda, P. A. Pearson Jul 2006

Data Mining And Image Segmentation Approaches For Classifying Defoliation In Aerial Forest Imagery, K. Fukuda, P. A. Pearson

International Congress on Environmental Modelling and Software

Experimental data mining and image segmentation approaches are developed to add insight towards aerial image interpretation for defoliation survey procedures. A decision tree classifier generated with a data mining package, WEKA [Witten and Frank, 2005], based on the contents of a small number of training data points, identified from known classes, is used to predict the extents of regions containing different levels of tree mortality (severe, moderate, light and non attack) and land cover (vegetation and ground surface). This approach is applicable to low quality imagery without traditional image pre-processing (e.g., normalization or noise reduction). To generate the decision tree, …

Modelling Support To Improve The Quality Of Environmental Studies, Huub Scholten Jul 2006

Modelling Support To Improve The Quality Of Environmental Studies, Huub Scholten

International Congress on Environmental Modelling and Software

Sound decisions in environmental management are often based on modelling, performed by teams consisting of team members with multidisciplinary backgrounds and solving multidisciplinary problems. Modelling in itself is a risky activity, in which many things can go wrong, including miscommunication within the team and between the team and the problem owner, malpractice, lack of process knowledge and a lack of documentation. This kind of problems makes modelling an obscure and arbitrary practice. The multidisciplinary character enhances the problem-solving scope of model studies, but does further increase the problems. Projects that use methods and tools for multidisciplinary model-based problem solving should …
