Estimating Energy Dissipation Due to Wave Breaking in the Surf Zone Using Infrared Imagery
Wave breaking is the largest forcing mechanism in the surf zone. Therefore, quantifying energy dissipation due to wave breaking is important for improving models that seek to predict nearshore circulation, wave-current ... -
Geometry, Kinematics & Energetics of Surf Zone Waves Near the Onset of Breaking Using Remote Sensing
The surf zone is the shallow nearshore region where waves break due to depth-limitations. These breaking waves drive important nearshore processes, including alongshore and cross-shore circulation, sediment transport, and ... -
Integrating Gravimetry Data with Thermal Infra-red Data from Satellites to Improve Efficiency of Operational Irrigation Advisory in South Asia
The rapid decline of groundwater resources in South Asia due to excessive irrigation during dry season requires awareness of optimal on-field water allocation requirements that is now being provided to farmer cellphones ... -
Long-term sediment yields from glacierized basins on Mount Baker, 1947-2015
Where glacierized watersheds are adjacent to population centers, sediment-laden rivers may catastrophically flood and the frequency of such flooding has been predicted to increase along with increased sediment supply. ... -
Mainstreaming multi-mission satellite observations in operational water resources management
Effective water management depends on the accuracy of three key components: monitoring, forecasting, and quantification of human impacts. Understanding complex hydrological processes and the vast amount of data are ... -
Mapping Snow Sensor Usability in the Northern Hemisphere with Google Earth Engine
Remote sensing provides a powerful tool for regularly observing seasonal snow properties across local, regional, and global spatial scales. Satellite Passive Microwave (PM) remote sensing provides a record of over 40 years ... -
Quantifying and Modeling Subgrid Scale Snow Depth Variability in Forested Areas Throughout Multiple Climates in the Western United States
The mountain snowpack provides natural storage of freshwater. This natural storage far exceeds the extent of manmade reservoirs. Furthermore, watersheds throughout the western United States can be predominantly covered in ... -
Quantifying seasonal snow using very-high-resolution stereo optical satellite images
Seasonal snow is one of the most dynamic components of the cryosphere. This water resource serves multiple roles in ecohydrology, climate modulation, and nutrient cycling. Measuring snow distributions is critical to ... -
Remote sensing of mountain snow surface temperatures at high temporal resolution using geostationary satellites
Remote sensing by geostationary satellites, such as by the NOAA GOES-R series with the Advanced Baseline Imager (ABI), can provide imagery of surface temperatures at high temporal resolutions due to their fixed views of ... -
Remote Sensing Surface Temperatures of Forests and Melting Snow at Different Spatial Scales
Uncooled thermal infrared (TIR) imagers, commonly used on aircraft and small unoccupied aerial systems (UAS, “drones”), can provide high-resolution surface temperature maps, but their accuracy is dependent on reliable ... -
Reservoir Assessment Tool 2.0: Stakeholder driven improvements to Satellite Remote Sensing based Reservoir Monitoring
In light of the rapidly increasing regulation of rivers due to planned and constructed reservoirs, monitoring reservoir operations has become very crucial. The Reservoir Assessment Tool (RAT) framework was developed to ... -
Reservoir Assessment Tool 3.0: An open source and user-friendly modeling platform to Mobilize the Global Water Community
Rivers, Earth's circulatory system for surface water, akin to human arteries, ensure water distribution for the planet. While these river networks are natural, human intervention has led to the construction of dams. In the ... -
Understanding the Impacts of Reservoirs in Developing Regions using Satellite Remote Sensing
Dams provide immense societal benefits in the form of hydropower generation, flood control, and water supply. However, they also cause significant negative environmental impacts by altering the timing and magnitude of ... -
Using High-resolution imaging satellite constellations to understand glacier mass balance and dynamics in High Mountain Asia
Meltwater from glaciers in High Mountain Asia (HMA) is an essential source of dischargefor major Asian rivers, which sustain one of the most densely populated regions on Earth. HMA glaciers are in a state of overall decline, ... -
Using Remote Sensing to Understand Urban Air Quality Exposures and Inequities
Outdoor air pollution is one of the leading causes of morbidity and mortality in the United States and around the world, but these impacts are not distributed equally. Countries, communities, and households that are socially ... -
Wave Breaking Dissipation in a Fetch-Limited Sea
(2013-04-17)Coupled remote sensing and <italic>in situ</italic> measurements of strongly-forced, fetch-limited waves are applied to assess the role of breaking in an evolving wavefield. Wave growth follows accepted fetch-limited ...
