Global riverbed median grain-size (D50) estimates for 8.5 million HydroRIVERS reaches

资源简介：
We develop a new global map of riverbed median grain size (D50) for more than 8.5 million HydroRIVERS reaches. This map is derived by combining measured and measurement-derived riverbed sediment D50 observations from the USGS, USACE, and published studies, global river-network geometry from HydroRIVERS, hydro-environmental watershed and reach characteristics from HydroATLAS/RiverATLAS, and state-of-the-art machine learning techniques.
