Grainsize distributions in rivers are highly variable while difficult to measure over long river reaches or entire river networks. Jordan Gilbert‘s work offers a statistical approach and numerical toolset to spatially estimate grainsize distributions.

Short summary
Characterizing the grain size of river sediments is necessary for estimating sediment transport rates in rivers. In order to understand sediment transport at large spatial scales, grain size information across river basins is needed, but methods for accomplishing this are limited. Here, I introduce a new method for using measurements of grain size in discrete locations to estimate full grain size distributions across entire watersheds.
