Addressing groundwater over-extraction in India: assessments, monitoring methods and interventions
(University of Waterloo, 2022-08-19)Groundwater is a vast distributed source of water that is critical for meeting the demands of various socio-environmental systems globally. However, the management of groundwater resources has proven to be challenging with ... -
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 ... -
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 ... -
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 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 ... -
The influence of winter time boreal forest tree transmissivity on tree emission and passive microwave snow observations
(University of Waterloo, 2019-05-17)Forest cover significantly attenuates natural upwelling ground microwave emission from seasonal terrestrial snow. This presents a major challenge for the accurate retrieval of snow from airborne or spaceborne passive ... -
Monitoring Ice-dammed Glacier Lake Outburst Floods in the Karakoram Using Visible-Infrared Satellite Remote Sensing Observations
(University of Waterloo, 2016-01-21)Glaciers are an important part of the hydrological cycle because they act as freshwater storage. Glacier ice contains about three-quarters of the world’s freshwater; supplying most of the base flow for rivers originating ... -
Monitoring Rainwater Harvesting Systems in India Using Satellite Remote Sensing Observations
(University of Waterloo, 2018-10-26)The building of small reservoirs is a typical measure taken by farmers to moderate the extremes of the hydrologic regime of a semiarid climate, which is characterized by the alternation of a short rainy season with long ... -
Satellite remote sensing observations of snow cover extent during the melt-out season in the Thompson-Okanagan Region, British Columbia from 2003-2019
(University of Waterloo, 2021-05-31)Snow is a critical component of the earth’s overall energy budget and it contributes significantly to water resources especially in mountainous regions, coining the term the “water towers” for downstream communities (Viviroli ... -
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, ... -
Snow Properties Retrieval Using Passive Microwave Observations
(University of Waterloo, 2019-04-30)Seasonal snow cover, the second-largest component of the cryosphere, is crucial in controlling the climate system, through its important role in modifying Earth’s albedo. The temporal variability of snow extent and its ... -
Wet Snow Mapping in Southern Ontario with Sentinel-1A Observations
(University of Waterloo, 2018-04-30)Wet snow is defined as snow with liquid water present in an ice-water mix. It can be an indicator for the onset of the snowmelt period. Knowledge about the extent of wet snow area can be of great importance for the monitoring ...
