Detecting Land Cover Change over a 20 Year Time Period in the Niagara Escarpment Plan Using Satellite Remote Sensing
(University of Waterloo, 2009-04-27)The Niagara Escarpment is one of Southern Ontario’s most important landscapes. Due to the nature of the landform and its location, the Escarpment is subject to various development pressures including urban expansion, ... -
Developing a Prototype Web-based Application for Non-Point Source Pollution Assessment in the Songtao Watershed, Hainan, China
(University of Waterloo, 2009-01-28)The Songtao reservoir, located in the center of Hainan province, is one of the ten biggest reservoirs in China. Since agriculture is the main industry in the watershed, non-point source (NPS) pollution is the primary ... -
Developing a radar-based machine learning snowfall retrieval algorithm
(University of Waterloo, 2023-01-03)As global temperatures continue to rise, snowfall patterns are expected to respond in a complex, nonlinear manner. Changes in the quantity of snowmelt-derived freshwater will impact global water-energy budgets, flood ... -
Developing a Suitability Index for Residential Land Use: A case study in Dianchi Drainage Area
(University of Waterloo, 2006)The conflict between residential land and agriculture land in China is increasingly sharpened, especially when some urban development began to sprawl to the suburban and rural areas. In order to plan land resources ... -
Developing Parameter Constraints for Radar-based SWE Retrievals
(University of Waterloo, 2021-09-28)Terrestrial snow is an important freshwater reservoir with significant influence on the climate and energy balance. It exhibits natural spatiotemporal variability which has been enhanced by climate change, thus it is ... -
Development of an Oil Spill Emergency Mapping System Using Internet GIS
(University of Waterloo, 2010-09-28)ince the 1970s, environmental monitoring in China has formed a complete web across the country with over 2000 monitoring stations. China State Environmental Protection Administration (SEPA) has published an annual report ... -
The Differing Influences of Soil Moisture and Antecedent Soil Moisture on the Timing and Magnitude of N2O Production
(University of Waterloo, 2012-10-22)Riparian soils are thought to be potential hotspots for nitrous oxide (N2O) fluxes from incomplete denitrification, with soil moisture cited as a primary controller, however, because there are multiple potential pathways ... -
Digital Terrain Models Generation from Airborne LiDAR Point Clouds Using A Multi-scale Terrain Filtering Method
(University of Waterloo, 2012-05-23)A Digital Terrain Model (DTM) is an important topographic product, required in many applications. Data needed to create a DTM was traditionally obtained via land surveying, however this method can be costly and time consuming ... -
Disabling cities
(Oxford University Press, 2017-01-13)Geographic research on disability and cities is wide-ranging and encompasses the lives of people dealing with disability, physical impairment, and issues of mental ill health. This chapter focuses on what makes cities more ... -
Disintermediating Government: The role of Open Data and Smart Infrastructure
(Hawaii International Conference on System Sciences, 2019)Governments are increasingly negotiating the adoption of civic technologies to improve government functioning and to better connect with citizens. Despite the benefits of civic technology to make government more efficient, ... -
Dissolved organic carbon concentration and character in northern hardwood-dominated headwater catchments: A paired-catchment investigation of legacy harvesting impacts
(University of Waterloo, 2023-08-01)The water quality of forested source water regions can be degraded by natural and anthropogenic landscape disturbances such as wildfires and forest harvesting, the latter an economically important primary industry in Canada ... -
Dissolved organic carbon production and transport in a constructed watershed in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2018-01-23)Within the Western Boreal Plains, a significant amount of surface cover has been removed through open-pit oil sands mining activities, which includes fen peatlands. Fen construction has been performed on the post-oil sands ... -
Downscaling Coarse Resolution Satellite Passive Microwave SWE Estimates
(University of Waterloo, 2020-05-26)The spatio-temporal heterogeneity of seasonal snow and its impact on socio-economic and environmental functionality make accurate, real-time estimates of snow water equivalent (SWE) important for hydrological and climatological ... -
Driver Response to Rainfall on the Gardiner Expressway
(University of Waterloo, 2004)Adverse weather conditions can increase travel risk. Understanding how drivers react to adverse weather, such as rainfall, can aid in the understanding of road safety patterns and traffic operations. This information ... -
Dual-polarization (HH/HV) RADARSAT-2 ScanSAR Observations of New, Young and First-year Sea Ice
(University of Waterloo, 2010-08-31)Observations of sea ice from space are routinely used to monitor sea ice extent, concentration and type to support human marine activity and climate change studies. In this study, eight dual-polarization (dual-pol) (HH/HV) ... -
The ecological effects of the cleared boundaries of Bruce Peninsula National Park
(University of Waterloo, 2009-11-19)Bruce Peninsula National Park (BPNP) clears a 2 m swath of trees on the boundary in order to make it clear when one is entering the park from any neighbouring land; this in particular aims to protect the park and its ... -
Edge of Field Phosphorus Export via Tile Drainage and Overland Flow from Reduced Tillage Systems in Ontario
(University of Waterloo, 2015-02-17)This study examined the role of tile drainage and overland flow in field-scale phosphorus (P) export from reduced tillage systems, as well as the influence of event type and antecedent conditions on P export during major ... -
Edge of Field Vegetated Buffers as a Potential Source of Dissolved Phosphorus over the Non-Growing Season in Cold Climates
(University of Waterloo, 2023-04-26)Phosphorus (P) rich runoff from agricultural landscapes are a major contributor to freshwater eutrophication issues. To intercept this runoff before it reaches waterways, vegetated buffer strips (VBS) are often employed ... -
