Abstract The Surface Water and Ocean Topography (SWOT) mission will vastly expand measurements of global rivers, providing critical new data sets for both gaged ungaged basins. SWOT discharge products (available approximately 1 year after launch) provide all river that reaches wider than 100 m. In this paper, we describe how produced archived by the US French space agencies be computed from water surface elevation, width, slope ancillary data, along with expected accuracy. We present first...
Abstract. The capabilities of radar altimetry to measure inland water bodies are well established, and several river datasets available. Here we produced a globally distributed dataset, the Global River Radar Altimeter Time Series (GRRATS), using Envisat Ocean Surface Topography Mission (OSTM)/Jason-2 altimeter data spanning time period 2002–2016. We developed method that runs unsupervised, without requiring parameterization at measurement location, dubbed virtual station (VS) level, applied...
Abstract The Surface Water and Ocean Topography (SWOT) satellite has the potential to transform global hydrologic science by offering simultaneous synoptic estimates of river discharge other hydraulic variables. Discharge is estimated from SWOT observations water surface elevation, width, slope. A first assessment using just highest quality measurements, over 15 months (March 2023–July 2024) mission evaluated at 65 gauged reaches shows results consistent with pre‐launch expectations. track...
The SWOT satellite has the potential to transform global hydrologic science by offering simultaneous and synoptic estimates of river discharge other hydraulic variables. Here, we present first from during initial orbital configuration mission. A preliminary accuracy assessment April 2023 shows results consistent with pre-launch expectations: can track dynamics without any gauge information. It captures magnitude correctly in some cases but bias others. Correlations a set representative...

Flooding is represented with a 2D hydrodynamic model over reach of the Ohio river between Cannelton and Newburgh locks dams. The geometry floodplain was provided by National Oceanic Atmospheric Administration (NOAA), based on U.S. Army Corps Engineers (USACE) survey channel data merged United States Geological Survey (USGS) LiDAR in overbank regions. description hydraulic structures from USACE in-situ water depth measurements USGS stations were also used.

Abstract River channels store large volumes of water globally, critically impacting ecological and biogeochemical processes. Despite the importance river channel storage, there is not yet an observational constraint on this quantity. We introduce a 26‐year record entirely remotely sensed volumetric storage (CWS) change 26 major world rivers. find mainstem CWS climatology amplitude (CA) represents appreciable amount basin‐wide terrestrial variability (median 2.78%, range 0.04%–12.54% across...

The forthcoming Surface Water and Ocean Topography (SWOT) mission will vastly expand measurements of global rivers, providing critical new datasets for both gaged ungaged basins. SWOT discharge products provide all river reaches wider than 100 m, but at lower accuracy temporal resolution what is possible in situ. In this paper, we describe how produced archived by the US French space agencies be computed from water surface elevation, width, slope ancillary data, along with expected accuracy....
