  abstract = {{F}luctuations in water surface elevation ({WSE}) along rivers have important implications for water resources, flood hazards, and biogeochemical cycling. {H}owever, current in situ and remote sensing methods exhibit key limitations in characterizing spatiotemporal hydraulics of many of the world's river systems. {H}ere we analyze new measurements of river {WSE} and slope from {A}ir{SWOT}, an airborne analogue to the {S}urface {W}ater and {O}cean {T}opography ({SWOT}) mission aimed at addressing limitations in current remotely sensed observations of surface water. {T}o evaluate its capabilities, we compare {A}ir{SWOT} {WSE}s and slopes to in situ measurements along the {T}anana {R}iver, {A}laska. {R}oot-mean-square error is 9.0cm for {WSE}s averaged over 1km(2) areas and 1.0cm/km for slopes along 10km reaches. {R}esults indicate that {A}ir{SWOT} can accurately reproduce the spatial variations in slope critical for characterizing reach-scale hydraulics. {A}ir{SWOT}'s high-precision measurements are valuable for hydrologic analysis, flood modeling studies, and for validating future {SWOT} measurements.},
