SWOT Water Surface Elevation in Herbaceous Wetlands of Florida's Everglades

Geophysical Research Letters
Observing water level variations in wetlands is important for tracking global water and carbon cycles. The Surface Water and Ocean Topography (SWOT) mission was launched to measure Earth's surface waters, but its performance in vegetated wetlands was ...

Anticipated Improvements to River Surface Elevation Profiles From the Surface Water and Ocean Topography Mission [PDF]

Frontiers in Earth Science, 2019
Existing publicly available digital elevation models (DEMs) provide global-scale data but are often not precise enough for studying processes that depend on small-scale topographic features in rivers.

Estimation of Small-Stream Water Surface Elevation Using UAV Photogrammetry and Deep Learning

Remote Sensing
Unmanned aerial vehicle (UAV) photogrammetry allows the generation of orthophoto and digital surface model (DSM) rasters of terrain. However, DSMs of water bodies mapped using this technique often reveal distortions in the water surface, thereby impeding

The Value of Distributed High-Resolution UAV-Borne Observations of Water Surface Elevation for River Management and Hydrodynamic Modeling

Remote Sensing, 2020
Water level or water surface elevation (WSE) is an important state variable of rivers, lakes, and wetlands. Hydrodynamic models of rivers and streams simulate WSE and can benefit from spatially distributed WSE observations, to increase model reliability ...

Experimental Investigation of Blowouts, Characterization of Fountain Effect Consequences at the Sea Surface

Chemical Engineering Transactions, 2020
The objective of this work was to quantify the consequences at the water surface of an underwater gas release. In particular the experimental tests were performed in two experimental basins, investigating the effect of gas nature, injection diameter and ...
