3D GIS Modelling of Road and Building Material Stocks: A Case Study of Grenada
(University of Waterloo, 2022-05-24)Recent years have witnessed significant material stock accumulation within built environments, resulting in substantial environmental issues, such as greenhouse gas emissions, toxic or harmful wastes, resource scarcity, ... -
Food Access Barriers and Supports for Youth in Thunder Bay, Canada
(University of Waterloo, 2022-05-24)The issue of youth food insecurity is examined in this thesis, in the context of a diverse urban centre which has a growing youth population and a high Indigenous presence. Literature review has identified gaps in academic ... -
Line-based deep learning method for tree branch detection from digital images
(Elsevier, 2022-06)Preventive maintenance of power lines, including cutting and pruning of tree branches, is essential to avoid interruptions in the energy supply. Automatic methods can support this risky task and also reduce time consuming. ... -
Phosphorus Responses to Soil Moisture in Southern Ontario Agricultural Soil
(University of Waterloo, 2022-04-29)Agricultural landscapes are known to increase phosphorus (P) losses to waterways, contributing to the eutrophication of freshwater surface water bodies. In cold agricultural regions, the nongrowing season drives annual P ... -
The State as a High Modernist Planner: Planning of Food System Transitions in Nanjing, China
(University of Waterloo, 2022-02-23)Food system planning is a nascent concept in both food studies and planning studies. Recent food planning studies point out that food issues have been mostly left out in modern planning practices and research, despite the ... -
Using stable water isotopes to partition source water contribution and assess spatio-temporal source water dynamics of wetlands ecosystems in the eastern Canadian Rocky Mountains
(University of Waterloo, 2022-01-28)Subalpine and montane regions of the Canadian Rocky Mountains are expected to experience continued changes in hydrometeorological processes due to anthropogenically-tied climate warming. These regions are important in ... -
Using Very High Resolution Remotely Piloted Aircraft Imagery to Map Peatland Vegetation Composition and Configuration Patterns within an Elevation Gradient
(University of Waterloo, 2022-01-28)GIS has developed over the decades from theory to highly accurate scientific observation using satellites that provide high resolution imagery. Over the last decade drones have been introduced to the world of GIS and ... -
Preferential recharge in a reclaimed tailings sand upland: Implications on solute flushing
(Elsevier, 2021-12)Study region: A peatland watershed was constructed on a post-mined oil sands lease in Northern Alberta, Canada, with the intention of replicating the function of natural wetlands removed by surface mining. Study focus: ... -
Remote sensing of chlorophyll-a in small inland waters
(University of Waterloo, 2022-01-26)Small inland waters (SIWs) – waterbodies smaller than 100 km2 – are the predominant form of lakes globally, yet they are highly subject to water quality degradation, especially due to harmful algae blooms (HABs). Space-borne ... -
Evaluation of Controlled Tile Drainage on Limiting Edge of Field Phosphorus Losses in a Clay Soil in a Cold Agricultural Region
(University of Waterloo, 2022-01-25)This study examined edge of field (EOF) discharge and phosphorus (P) losses from a Brookston clay soil in a cold agricultural region over four years and quantified the influence of controlled tile drainage (CD) on seasonal ... -
Snow Depth Retrieval from Wide Band Radar in Trail Valley Creek
(University of Waterloo, 2022-01-18)Snow is an essential component in hydrology systems, and more speci cally, monitoring variations in snow cover can provide valuable information about water supply, wildlife habitats, and climate changes. In recent years, ... -
Impacts Of Seismic Line Restoration Techniques On Nutrient Biogeochemical Processes In A Boreal Fen
(University of Waterloo, 2021-12-23)Peatlands contain 40 cm or more of partially-decomposed plant matter and sequester carbon and nutrients. The disturbance of peatlands alters these ecological functions. Seismic lines, long cutlines in the forest created ... -
Balancing Interests in Regulatory Institutions: A Comparison of the Northern Gateway and Keystone XL Pipelines
(University of Waterloo, 2021-12-20)Canada and the United States are facing crucial decisions about the future of their energy resources. The severity of climate change, increasing salience of the social impacts of fossil fuel development, and mounting calls ... -
Quantifying and Modelling Post-Wildfire Sediment Production in Waterton Lakes National Park
(University of Waterloo, 2021-12-16)High-severity wildfires can increase sediment mobility and erosion rates in burned landscapes which increase the delivery of fine sediment to receiving streams. The downstream propagation of these pyrogenic materials can ... -
Land Disturbance Extraction in Alberta Oil Sands Satellite Imagery
(University of Waterloo, 2021-12-10)Tracking and mapping land disturbances from oil and gas development are critical to environmental assessments and land reclamation. Manual extraction of land disturbances is costly, time-consuming, and requires updating ... -
Participatory Augmented and Virtual Reality: A comparative case study recognising its viability in citizen participation
(University of Waterloo, 2021-10-25)With technology’s growth in recent years, governments have begun adopting new methods of citizen participation into decision-making. New technologies require a deep analysis of their implementation, to understand and ... -
Investigating the Spatial Patterns of Income Inequality and Crime: Applications of Spatiotemporal Data Analysis Techniques
(University of Waterloo, 2021-10-25)Income inequality and crime are two social problems concerning many nations around the world. Such social issues can have detrimental effects on society and are interconnected, meaning that high crime rates may be associated ... -
Impacts of seismic line restoration on CO2, CH4, and biomass
(University of Waterloo, 2021-10-21)Oil and gas exploration has resulted in over 300,000 km of linear disturbances, known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that ... -
Measuring and modelling soil erosion in agricultural systems: Evaluating the application of UAVs and SfM-MVS for soil erosion research
