Assessment Of The Co2 Capture Potential From Irreplaceable Industrial Sources, Peter Psarras, Jennifer Wilcox

CO2 Summit II: Technologies and Opportunities

The industrial sector represents approximately 20% of total US CO₂ emissions.¹ These emissions can be further categorized as direct (accountable on-site, e.g., stationary combustion), indirect (assigned to electricity purchased for power) and process (CO₂ liberated as a reaction by-product). For example, steel and cement production both involve processes that directly emit CO₂ as a by-product (via the oxidation of metallurgical coke and conversion of calcium carbonate to lime, respectively). While climate change mitigation efforts have the potential to reduce direct and indirect emissions through the adoption of best practice technologies and low-carbon energy sources, process emissions …

Estimating The Probability Of Vegetation To Be Groundwater Dependent Based On The Evaluation Of Tree Models, Isabel C. Pérez Hoyos, Nir Y. Krakauer, Reza Khanbilvardi

Publications and Research

Groundwater Dependent Ecosystems (GDEs) are increasingly threatened by humans’ rising demand for water resources. Consequently, it is imperative to identify the location of GDEs to protect them. This paper develops a methodology to identify the probability of an ecosystem to be groundwater dependent. Probabilities are obtained by modeling the relationship between the known locations of GDEs and factors influencing groundwater dependence, namely water table depth and climatic aridity index. Probabilities are derived for the state of Nevada, USA, using modeled water table depth and aridity index values obtained from the Global Aridity database. The model selected results from the performance …

Laboratory Exercise- Mapping The Risk Of Structural Failure In Schools Due To An Earthquake, Joel Barker, Kimberly Sowards, Casey Webb

Engineering Applications of GIS - Laboratory Exercises

Utah’s present geology has been greatly dictated by tectonic stresses that have occurred over the last 0.7 Ga. A determining factor in much of this Geology is the Hingeline that runs through Salt Lake County. Throughout the history of the western North America, this has been an important weak zone. It is no surprise that this same zone is now home to the Wasatch Fault System, which accommodates some of the extension of Western North America. The steep mountains facing west toward Salt Lake City were formed from the tectonic processes of the Fault. The Wasatch Fault is a normal …

Child Safety Near Pot Shops In Denver, Jacob Flansberg, Elise Jackson, Amelia Theobald

Engineering Applications of GIS - Laboratory Exercises

Some major factors in deciding where one’s family should live include relative safety of the neighborhood, available green space such as parks and schools, grocery stores, and other commercial retail in the area. With the legalization of marijuana in states such as Colorado, proximity of these marijuana dispensaries has become another factor. The Normalized Difference Vegetation Index (NDVI) can be used as a measure of vegetation, and to determine areas with high levels of irrigated vegetation. Using ArcGIS Modelbuilder, the data from an NDVI analysis can be used to determine the proximity of marijuana shops to these types of greenspaces …

Pumpage Reduction By Using Variable Rate Irrigation To Mine Undepleted Soil Water, Tsz Him Lo, Derek M. Heeren, Derrel Martin, Luciano Mateos, Joe D. Luck, Dean E. Eisenhauer

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Conventional irrigation schedules are typically based on portions of the field where root zones hold the least available soil water. This leaves undepleted available water in areas with larger water holding capacities. The undepleted water could be used through variable-rate irrigation (VRI) management; however, the benefits of VRI without in-field mapping are unexamined. In this research, the field-averaged amount of undepleted available soil water in the root zone was calculated from the NRCS Soil Survey Geographic database for 49,224 center-pivot irrigated fields in Nebraska. Potential reductions in pumpage from mining undepleted available water were then estimated. Results of the analysis …

Potential Irrigation Reductions From Increasing Precipitation Utilization With Variable Rate Irrigation, Tsz Him Lo, Derek M. Heeren, Luciano Mateos, Joe D. Luck, Derrel L. Martin, Dean E. Eisenhauer

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Much of the previous research quantifying the potential benefits of variable rate irrigation (VRI) consists of case studies with simulations using data from small numbers of intensely sampled fields. In this study, an indicator of the amount of root zone available water capacity that is unutilized by uniform rate irrigation was calculated for 49,224 center pivot irrigated fields in Nebraska using publicly available data exclusively. Based on the values of this indicator, potential seasonal irrigation reductions from increasing precipitation utilization with VRI were estimated to be high for a small fraction of analyzed center pivots but low on a regional …

After initial validation, the InSAR data (over 1.67 million data points comprising various “scatterers”) were brought into a GIS dataframe and georeferenced to locations of known sinkholes. This dataset was then used to evaluate karst hazard within a 40x40km data frame located in the Valley and Ridge Province of Virginia. The group identified systematic kinematic differences in …

Integrated Freight Network Model: A Gis-Based Platform For Transportation Analyses, Ted H. Grossardt, John Ripy, Benjamin L. Blandford, Michael Shouse

Kentucky Transportation Center Research Report

The models currently used to examine the behavior transportation systems are usually modespecific. That is, they focus on a single mode (i.e. railways, highways, or waterways). The lack of integration limits the usefulness of models to analyze the intermodal movement of freight. This project developed a GIS-based model of the three primary surface modes as well as intermodal connections. The resulting Integrated Freight Network Model (IFNM) accommodates highly detailed about shipping costs, transfer costs, traffic volumes (including non-freight auto traffic), and network interconnectivity properties. As a proof of concept, the research team conducted an exploratory analysis that asked what the …

Gis-Based Route Risk Assessment Of Hazardous Material Transport, Myungwoo Lee

Modeling Of Urban Planning Actions By Complex Transactions On Semantic 3d City Models, Maximilian Sindram, Thomas H. Kolbe

International Congress on Environmental Modelling and Software

Decision support for environmental planning requires the impact analysis of envisaged actions. These actions often are adapted from measures specified in regulations or other legal doc­uments given in natural language. Their realization involves (possibly complex) changes to specific parts of the environment. For example, the energetic retrofitting of a building typically comprises the insulation of the faҫade and replacement of the windows. In general, different actions or combinations of actions can be chosen for the optimization of certain key performance indicators (KPI) like the over­ all energy demand or C0₂ emission of a city district. This requires the assessment …

International Congress on Environmental Modelling and Software

The need to reduce the use of pesticides in agricultural ecosystems requires studying and developing new pest regulation methods. Individual-based models are useful to better understand how dynamics of insects interact with agricultural landscapes and to study the potential effects of alternative regulation methods, taking into account the spatial and temporal stochasticity of agricultural ecosystems caused by human management. Crop rotations and crop phenology have an important impact on the life cycles of populations of insects. We developed an individual-based model simulating the dynamics of an agricultural landscape from GIS data. The spatiotemporal stochasticity is simulated using typical landcover rotations …

Investigating Virtual Globes For A Prototype Community Archive Of 3d Subsurface Data, Derek C. Whitman

Theses and Dissertations

Geoscience data sharing and processing is very advanced in terms of surface data. Subsurface data sharing has not received the attention that surface data sharing has received and so there are fewer applications or software packages which focus on it. This research is funded by the NSF EarthCube GEO Domain program in an effort to develop a continental-scale repository of 3D subsurface data to facilitate the sharing of complex 3D data and to enable the development of geoprocessing tools and workflows that operate on that data.

Risk Assessment Model For Pipe Rehabilitation And Replacement In A Water Distribution System, Jan C. Devera

Master's Theses

The efficient delivery of potable water for a community through its distribution system has historically been the backbone of nearly all metropolitan developments. Much of these systems are comprised of pipe networks made of various materials including concrete, iron, PVC, and even steel. As these communities expand and urbanize, water demand and population density simultaneously increase. This develops higher strains and stresses in the community‟s water distribution network causing pipes to corrode, crack, or rupture prematurely while in service. As a result, the deterioration of water distribution systems in growing cities is increasingly becoming a major concern for our nation. …

Gis-Based Flood Analysis For Adequate Flood Mitigation In An Unplanned Urban Area; The Case Of Pikine Dagoudane In Dakar County, Senegal, Sokhna Helene Diop

Masters Theses

Since 1989, Pikine Dagoudane, in the suburbs of Dakar City has faced several flooding events, resulting in economic loss, environmental degradation and severe disturbance of the social life of the residents. The mitigation programs implemented have not appeared to provide any relief since 2000. Review of the existing literature on the crisis has revealed that the general scale of the studies, and the insufficient attention to some of the major factors could be accounted for such little efficiency. This thesis applies a different approach, based on a small area and focusing mainly on topographic characteristics, to provide a better understanding …

Nutrient Contribution Of The Shallow Unconfined Aquifer To Pineview Reservoir, Thomas Nyanda Reuben

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pineview Reservoir, near Utah’s populous Wasatch Front, could play an important role in modulating water supply as water demands and water uses change in response to increasing population densities. The reservoir’s water quality may decline if nitrogen and phosphorus additions to the reservoir are not controlled. Most of the water flowing into the reservoir in summer and fall is contributed by the shallow ground water. The quantity and quality of the shallow ground water to Pineview Reservoir were studied from February 2010 through November 2011. The objectives were to: 1) increase understanding of nitrogen and phosphorus transport from ground water …
