Identification of soil particle size distribution in different sedimentary environments at river basin scale by fractal dimension [PDF]

open access: yesScientific Reports, 2022
The geomorphology of river basin is complex, and its soil sedimentary characteristics are poorly defined. To study the spatial variability of soil structure in different sedimentary environments at the basin scale, 356 sets of soil samples were collected
