You mention sediment transport capacity (gsd) at the end of the filter; how do you calculate sediment transport capacity?
In fact gsd is also called sediment load in the manual. This is calculated depending of the region of the filter. The basic idea is to compare the calculated value of gsd with the incoming sediment concentration. If gsd> sediment concentration, the difference is allowed to deposit in whatever section of the filter is being calculated (coarse sediment at wedge, or fine sediment at the lower section of the filter). Return to top The equations have a dp or median particle size, but it seems that some particle size distribution must be implicit in the equations. I am a bit confused how dp or d50 can simulate the deposition realistically if it is a single particle size. Clearly different sized particles settle at different rates and a single particle size specification must be implying some distribution. This is a good question. Although this clearly assumes a certain type of distribution, or at least the d50 can represent realistically the population of sediment particles entering the filt
