Evaluating Aerial Ku-Band Radar Altimetry over Landfast First-Year Sea Ice
(University of Waterloo, 2020-01-17)Recent studies have challenged the assumption that Ku-band radar, used by the CryoSat-2 satellite altimetry platform, fully penetrates the dry snow cover of Arctic sea ice in the winter. There is also uncertainty around ... -
Evaluating flood risk governance with geospatial technologies
(University of Waterloo, 2023-05-02)The concept of governance for flood resilience has gained traction in scholarship and practice over the last 15 years. Governance is distinct from government as it recognizes that flood risk management (FRM) is carried out ... -
Evaluating Multi-Temporal DInSAR Measurements of Ground Surface Deformation Around the Rhenish Coalfields in Germany Using Sentinel-1 SAR Imagery
(University of Waterloo, 2021-06-01)Ground surface deformation caused by land subsidence is a critical aspect when assessing safety and environmental impacts of open-pit mining operations. These mining-induced deformations can cause severe damage to local ... -
Evaluating parameter fitting and model design for unsaturated processes in peatlands
(University of Waterloo, 2019-04-08)Growing Sphagnum moss for peatland restoration and fibre farming requires the proper moisture regime be maintained; thus, there is a desire to optimize growth by creating ideal hydrological conditions. Sphagnum mosses have ... -
Evaluating remotely piloted aircraft estimates of crop height and LAI against satellite and crop model outputs
(University of Waterloo, 2021-02-17)Crop simulation models (CSM) have been a method for decision makers to study the effects of crop management activities for predicting, planning, and improving crop growth for the past several decades. While the applicability ... -
Evaluating Tailored Feedback for Re-Engaging Residential Smart Grid Users: A Case Study in Milton, Ontario
(University of Waterloo, 2016-04-01)A rapidly changing climate, predominantly caused by carbon-intensive human activities, has stimulated policies and programs to reduce greenhouse gas emissions (GHG’s). One area in which GHG reductions are being made is in ... -
Evaluation of a Soil Radar Backscatter Model with Applicability to Radar Observations of a sub-Arctic Environment
(University of Waterloo, 2013-10-11)This research explores the applicability of a soil backscatter model for estimating X-band (9.35-9.85 GHz) backscatter from snow covered sub-Arctic terrain in the Hudson Bay Lowlands, Manitoba, Canada. The studied radar ... -
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 ... -
An evaluation of engineered media for phosphorus removal from greenroof stormwater runoff
(University of Waterloo, 2011-04-08)Greenroofs are increasingly being recognized as an effective site level best management practice (BMP) to reduce the volume of stormwater runoff in urban environments. For some water quality constituents, greenroofs can ... -
An evaluation of high-resolution land cover and land use classification accuracy by thematic, spatial, and algorithm parameters
(University of Waterloo, 2017-09-29)High resolution land cover and land use classifications have applications in many fields of study such as land use and cover change, carbon storage measurements and environmental impact assessments. The wide range of ... -
Evaluation of Machine Learning Algorithms for Lake Ice Classification from Optical Remote Sensing Data
(University of Waterloo, 2020-06-02)The topic of lake ice cover mapping from satellite remote sensing data has gained interest in recent years since it allows the extent of lake ice and the dynamics of ice phenology over large areas to be monitored. Mapping ... -
Evaluation of Machine Learning Algorithms for the Classification of Lake Ice and Open Water from Sentinel-3 SAR Altimetry Waveforms
(University of Waterloo, 2023-01-18)Lakes cover a significant fraction of the landscape in many northern countries. They play a key role in regulating weather and climate and also have a significant impact on northern communities since the presence (or ... -
An evaluation of moisture dynamics and productivity of Sphagnum and Tomenthypnum mosses in western boreal peatlands, Canada
(University of Waterloo, 2014-05-22)Western boreal peatlands have diverse ground covers of Sphagnum and brown mosses that have important hydrological controls on peatland-atmosphere interactions. Since peatland mosses are non-vascular, their shoot structural ... -
Evaluation of safety effects of roundabouts in the Region of Waterloo: inclement weather and conversion
(University of Waterloo, 2017-05-19)Roundabouts, as a form of intersection traffic control, significantly improve safety and efficiency. In Canada, the benefits of roundabouts have drawn growing interest, and roundabouts are being constructed increasingly ... -
Evaluation of soil chemical and physical characteristics in a complex agroecosystem in the Argentine Pampa
(University of Waterloo, 2010-12-16)The Argentine Pampa is a global producer of maize (Zea mays L.) and soybean [Glycine max L. (Merr.), however agricultural practices have caused severe soil degradation and amplified greenhouse gas (GHG) production rates. ... -
Evaluation of the albedo parameterization of the Canadian Lake Ice Model and MODIS albedo products during the ice cover season
(University of Waterloo, 2013-06-21)Snow and lake ice have very high albedos compared to other surfaces found in nature. Surface albedo is an important component of the surface energy budget especially when albedos are high since albedo governs how much ... -
An evaluation of the water balance and moisture dynamics within Sphagnum mosses following the restoration (rewetting) of an abandoned block-cut bog
(University of Waterloo, 2011-09-30)Artificial drainage networks established throughout peatlands during the peat extraction process often remain active following abandonment, maintaining a water table relatively far from the surface of the peat and hindering ... -
An Evaluation of Trend and Anomalies of Arctic Sea Ice Concentration, 1979-2006
(University of Waterloo, 2013-05-23)As a part of the Cyrosphere ecosystem, Arctic sea ice is one of the focal points when studying Arctic climate change. Arctic sea ice image has been documented by remotely sensed data since the 1970s. By examining these ... -
