Computer-Based Forage Management Tools: Historical, Current, And Future Applications, David B. Hannaway, C. Daly, D. F. Chapman, B. B. Baker, A. S. Cooper

International Grassland Congress Proceedings

Forage management has been an important human activity since the beginning of civilization. By comparison, the personal computer has been available only in the immediate past. The software developed to deal with the complexity of climate, soil, plant, animal, and socioeconomic factors has seen huge changes in a few decades. Mainframe computers facilitated numerical calculations for exploring relationships among dozens of variables. Personal computers opened the door for more individual scientist creativity and routine communication. Web-based communication globalised the option for multidisciplinary teams to tackle problems. Forage-related computer applications abound, allowing farmers, ranchers, and others to more effectively manage the …

Gis Data: Charles County, Maryland Shoreline Situation Report, Karinna Nunez, Tamia Rudnicky, Sharon Killeen, Jessica Hendricks, Catherine R. Duning, Evan Hill

Data

Shoreline Situation Reports (SSR) were first generated by VIMS in the 1970s to report the condition and status of the shore lands. The SSR series were published in hardcopy on a county by county basis for each of the Tidewater Virginia localities. The reports were intended to assist planners, managers, and regulators in decisions pertaining to management of coastal areas and natural resources therein. The techniques developed for Virginia's shoreline are used to create similar reports for the Maryland shoreline. Data collected describes conditions in the immediate riparian zone, the bank, and along the shore.

Application Of Geospatial Technologies For Urban Planning And Management, Flood Modelling, Urban Heat Island, Water Resources Management And Planning, Hydrological Modelling, Climate Change And Water Quality Modelling Etc., Anoop Kumar Shukla Dr.

Basic Science Collection

Human activities are altering the natural landscape on the earth’s surface. The thermal environment of densely populated cities is also experiencing rapid change. Remote sensing provides the necessary spatial and temporal data to understand cities' complex human–climate interactions. However, the complex temporal and spatial variability of human activities, urban landscapes, and urban climates make understanding the interactions among them challenging. The study of human–climate interactions is also complicated by the mixed pixels of remote sensing data.

Therefore, I am looking to collaborate with those who want to do research in the field of Remote Sensing and GIS application in water …

Changes Of Winter Severity In Arkansas During 1901-2100, Christian Garcia Aug 2022

Changes Of Winter Severity In Arkansas During 1901-2100, Christian Garcia

Graduate Theses and Dissertations

The objective of this study was to quantify the winter severity in a way that was reproduceable and easy to understand. The Accumulated Winter Severity Seasonal Index (AWSSI) was chosen for this reason and was used to quantify winter severity by season across the state of Arkansas. The variables that go into the AWSSI calculation are maximum daily temperature, minimum daily temperature, daily snowfall, and daily snow depth. When the snowfall and snow depth were missing, they can be estimated using daily temperature and precipitation. Then the estimated snowfall and snow depth can be subsequently used to quantify the winter …

A Gis Suitability Model Evaluating Habitat Characteristics Influencing Beaver (Castor Canadensis) Lodge Site Selection And Lodge Occupancy In Central Adirondacks, New York, Amanda K. Jacobs Jul 2022

A Gis Suitability Model Evaluating Habitat Characteristics Influencing Beaver (Castor Canadensis) Lodge Site Selection And Lodge Occupancy In Central Adirondacks, New York, Amanda K. Jacobs

Theses - ALL

The North American beaver (Castor canadensis) represents a quintessential example of an "ecosystem engineer." Yet the species' landscape-scale impacts on hydrology, geomorphology, and ecosystem ecology are not uniformly distributed through landscapes or time. Understanding beaver lodge site selection and lodge fidelity through time can help to predict where the greatest effects of beaver activity may occur. In this research project, I seek to understand the relationships between beaver habitat suitability, the habitat variables that currently define suitable areas, and lodge occupancy over time. Using Geographic Information Systems (GIS) to model habitat suitability, I use hydrologic, vegetative, and physiographic variables to …


Evaluation Of Measurement Data Across Eight Gis Basemaps Using Drumlins: Combining Basemaps Is Optimal, Gretchen A. Wambach, Alexander K. Stewart Jun 2022

Evaluation Of Measurement Data Across Eight Gis Basemaps Using Drumlins: Combining Basemaps Is Optimal, Gretchen A. Wambach, Alexander K. Stewart

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Choosing the best basemap for landform data collection and analysis is fundamental for accurate measurements and usability. Different types of basemaps may affect how we perceive relief through a map (Phillips et al., 1975); thereby, affecting the precision of data collected. This project collected length and azimuth data of 60 drumlins in Western, NY from four different, ArcGIS online (AGOL)-provided basemaps, as well as two parallel-to-strike and two perpendicular-to-strike hillshades (n=4). Testing the mean length (1,662m, ±529) and azimuth (171°, ±0.3) data for uniformity across basemaps determined if any basemap is more or less reliable for data collection. The Terrain …


Structural Geology And Cenozoic Deformation: Western Northern Range, Trinidad, Abigail Faye Clark May 2022

Structural Geology And Cenozoic Deformation: Western Northern Range, Trinidad, Abigail Faye Clark

Geology: Student Scholarship & Creative Works

The Northern Range, Trinidad underwent deformation due to oblique collision of Caribbean plate with northern South America, which was then followed by transform plate motion. Deformation began in the late Miocene when sedimentary protoliths were ductility deformed and metamorphosed to greenschist facies; this event and subsequent transform deformation drove exhumation of these rocks to the surface and created their high topography. This project provides constraints of the structural history of the western Northern Range where bedrock mapping and structural analyses are most complete. Initial geologic mapping of Northern Range, which continued from the 1950s,1960s, and 1990s, focused on attempting to …


Using Lidar To Estimate Carbon Sequestration Of Evergreen Trees At Eastern Washington University (Ewu) Campus, Cheney, Washington, Kristy A. Snyder May 2022

Using Lidar To Estimate Carbon Sequestration Of Evergreen Trees At Eastern Washington University (Ewu) Campus, Cheney, Washington, Kristy A. Snyder

2022 Symposium

EWU contains a variety of deciduous and evergreen trees across its campus, providing several benefits. However, no comprehensive record exists of the total number, location, species, or ages of these trees. This knowledge can inform facilities of proper care for individual trees and can be used to estimate carbon sequestration on campus. Traditional on-the-ground methods for assessing trees require tree cores or clinometers, making trees susceptible to pests or disease and leading to inaccurate results. Remote sensing using lidar data is a noninvasive, more precise method to measure tree height and subsequently assess tree age. This poster explores using point …

Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws May 2022

Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws

Dissertations & Theses in Natural Resources

Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …

Titanium is commonly used in the aerospace industry because it is lightweight and durable in extreme temperatures. The Green Cove Springs Mine, near Green Cove Springs, Florida, was used for mining and processing titanium and other minerals from 1972 until 2009. Since then, the mine area is being reclaimed, or rehabilitated and restored to its natural state, as required by Florida Department of Environmental Protection regulations. In this study, we use high-resolution multispectral satellite and aerial imagery obtained from 2016 to 2022 to examine land cover (LC) changes at the Green Cove Springs Mine during this reclamation period. We use …


Changes To Maine's Winter Weather, Alexander Ingalls Apr 2022

Changes To Maine's Winter Weather, Alexander Ingalls

Undergraduate Theses

The properties of winter weather in Maine are examined using several forms of analysis to illustrate changes in winter weather patterns over the past 40 years. While previous studies have determined several ways that climate change affects the entire state, this study seeks to better understand the impact of these changes in five specific regions. The resulting analyses shows how certain atmospheric variables such as precipitation, temperature, and snowfall vary in magnitude and location across the state and over time. The results suggest these changes have different consequences for different areas of the state.

Student Publications

In addressing the decline of North American grassland bird populations, it is important to consider the various interdisciplinary approaches that can be employed in their conservation. OECMs, or “other effective area-based conservation measures” encompass a wide array of strategies which can be leveraged to conserve natural landscapes and species. Land easements implemented by the Land Conservancy of Adams County (LCAC) are an example of one such strategy. The LCAC seeks primarily to preserve the rural character of Adams County but has more recently turned their focus toward environmental conservation. In partnering with the Land Conservancy, this case study aimed to …


The Role Of Physical Geographic Features In Video Games, Dexter Ferguson Apr 2022

The Role Of Physical Geographic Features In Video Games, Dexter Ferguson

Theses

This thesis examines how physical geographic features affect individuals when interacting with video game environments. There are very few studies on the geography of video games. I aim to bridge the gap between game studies and geography, a naturally occurring link. The observation of elements such as the geography of an area is critical when exploring an individual’s perception of a video game environment. Individuals interact with the geography of their location on a day-to-day basis, whether it be physical or human geography; how they can relate a video game’s geography to the real world dramatically affects their immersion. An …


Safe Water For All: A Multi-Modal Approach To North Alabama's Water Resources, Elijah Walker Apr 2022

Safe Water For All: A Multi-Modal Approach To North Alabama's Water Resources, Elijah Walker

Theses

Environmental degradation is a destructive force produced by the human disturbance of pollution. It is a phenomenon that gradually evolves landscapes over time resulting in irreversible outcomes. Environmental degradation physically affects spaces’ resources, objects, and inhabiting humans. This study observes the impacts of pollution beyond physical boundaries and how it affects human identity/sense of place through the utilization of geographic information systems. Specifically, it examines cultural identity developed through human experiences and connections to landscapes containing water resources. Following, pollution contaminates water resources disrupting experiences and connections thus causing the cultural identity to disappear. The case study applied to this …

Evaluating Remote Economic Benefits Of Watershed-Scale Acid Mine Drainage Restoration, Rachel E. Pell Jan 2022

Evaluating Remote Economic Benefits Of Watershed-Scale Acid Mine Drainage Restoration, Rachel E. Pell

Graduate Theses, Dissertations, and Problem Reports

In 2011, the West Virginia Abandoned Mine Lands and Reclamation Program (WVAML) implemented a watershed-scale restoration project in Three Fork Creek, a 103 square-mile watershed in rural West Virginia impaired by acid mine drainage (AMD). This was accomplished through the installation of four in-stream lime dosers in 2011. Due to the great capital investment in the restoration of Three Fork Creek and an interest in applying this watershed-scale approach to other watersheds throughout West Virginia, it is of great interest to demonstrate the successes of this remediation. It has already been demonstrated that the watershed has visibly improved and is …
