Operational Near Real Time Global Riverine Sediment Flux Estimates From Space
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We present global estimates of riverine sediment flux derived from an open‐source suite of algorithms using the Harmonized Landsat Sentinel (HLS) and discharge products. We estimated Sediment Concentration (suspended sediment concentration [SSC]) via neural networks, trained and tested on matchups of in situ and HLS data, obtaining a median ...
