[[category:Characteristic Numbers (independent of the presence of tides)]]

==Motivation==

Computation as well as visualization of the tide independent characteristic numbers of suspended [[sediment transport]] gives some insight into the
* local (rate of change) of suspended sediments (mass), 
* mean (horizontal) suspended [[sediment transport]] due to advection,
* mean (horizontal) suspended [[sediment transport]] due to diffusion, 
* strength of sources and sinks, as well as
* sediment exchange between water body and bottom (deposition and [[erosion]])
within the [[period of data analysis]].

From these, conclusions can be drawn on the mean (residual) transport of suspended sediments, and i. e. the relative significance of advection versus diffusion. Also the significance of deposition and [[erosion]] can be elaborated. For estuaries, fresh water flow, bathymetry, as well as wind shear are considered to be the main influencing factors.
