Abstract The upcoming Surface Water and Ocean Topography (SWOT) satellite mission, planned to launch in 2022, is the first mission focus on measuring hydrological processes Earth's surface water. As such, SWOT will vastly expand observations of global rivers ≥100 m wide. provide a variety data products, including vector river product containing water elevation (WSE), width, slope, estimated discharge. Practical application consistency products requires prior network database divided into...
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 Rivers are among the most imperiled ecosystems globally, yet we do not have broad‐scale understanding of their changing ecology because rarely sampled. Water color, as perceived by human eye, is an integrative measure water quality directly observed satellites. We examined patterns in river color between 1984 and 2018 building a remote sensing database surface reflectance, RiverSR, extracted from 234,727 Landsat images covering 108,000 kilometers rivers > 60 m wide contiguous...
Abstract Fluctuations in water surface elevation (WSE) along rivers have important implications for resources, flood hazards, and biogeochemical cycling. However, current situ remote sensing methods exhibit key limitations characterizing spatiotemporal hydraulics of many the world's river systems. Here we analyze new measurements WSE slope from AirSWOT, an airborne analogue to Surface Water Ocean Topography (SWOT) mission aimed at addressing remotely sensed observations water. To evaluate...
Abstract To help store water, facilitate navigation, generate energy, mitigate floods, and support industrial agricultural production, people have built continue to build obstructions natural flow in rivers. However, due the long complex history of constructing removing such obstructions, we lack a globally consistent record their locations types. Here, used method visually locate classify on 2.1 million km large rivers (width ≥30 m) globally. We based our mapping Google Earth Engine’s high...
Abstract As modeling capabilities at regional and global scales improve, questions remain regarding the appropriate process representation required to accurately simulate multichannel river hydraulics. This study uses hydrodynamic model LISFLOOD‐FP patterns of water surface elevation (WSE), depth, inundation extent across a ∼90 km, anabranching reach Tanana River, Alaska. To provide boundary conditions, we collected field observations bathymetry WSE during 2 week campaign in summer 2013. For...
Abstract ArcticDEM is a collection of 2‐m resolution, repeat digital surface models created from stereoscopic satellite imagery. To demonstrate the potential for measuring river stages and discharges, we estimate heights along reach Tanana River near Fairbanks, Alaska, by precise detection shorelines mapping to land elevation. The height profiles over 15‐km agree with in situ measurements standard deviation less than 30 cm. time series ArcticDEM‐derived U.S. Geological Survey gage 32 Using...
AirSWOT, an experimental airborne Ka-band interferometric synthetic aperture radar, was developed for hydrologic research and validation of the forthcoming Surface Water Ocean Topography (SWOT) satellite mission (to be launched in 2021). AirSWOT SWOT aim to improve understanding surface water processes by mapping elevation (WSE) slope (WSS) rivers, lakes, wetlands. However, utility these purposes remains largely unexamined. We present first investigation WSE WSS surveys over complex,...
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. For example, slope breaks and knickpoints rivers can be important understanding tectonic processes, riffle-pool structures drivers of riverine ecology. More (e.g. lidar) some areas, their spatial extent limits large-scale research. The upcoming Surface Water Ocean Topography (SWOT) satellite...
Abstract In situ river discharge estimation is a critical component of studying rivers. A dominant method for establishing monitoring in temporary gauge, which uses rating curve to relate stage discharge. However, this approach constrained by cost and the time develop stage‐discharge curve, as curves rely on numerous flow measurements at high low stages. Here, we offer novel alternative traditional gauges: estimating Discharge via Arrays Pressure Transducers (DAPT). DAPT Bayesian algorithm...

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.
