TL;DR: In this paper, the authors examined the river sediment discharge of the four major rivers in the upper Chao Phraya River basin in Thailand and found that the amount of total sediment discharge in each river caused by the 2011 flooding varied between 0.3 and 1.6 mt.

TL;DR: In this paper, a study was carried out on the velocity profile of sediment-laden flows in open channels using a two phase mixture model for two-phase flows, where the drift velocity was derived from the equation of momentum conservation for the solid phase and the inertia of flow, particle turbulence and collisions effect contributed to the dispersion of the sediment particles in turbulent flows.
