[1] New space-based observations of South Florida
with interferometric SAR (InSAR) reveal spatially
detailed, quantitative images of water levels in the
Everglades. The new data capture dynamic water level
topography, providing the first detailed picture of wetland
sheet flow. We observe localized radial sheet flow in
addition to well-known southward unidirectional sheet
flow, modelled as a linear diffusive flow. We obtain
quantitative estimates of flow diffusivity (2391 m2
/s),
the first space-based estimates of such hydrologic parameter
for the Everglades. Space-based hydrologic observations can
