If humans do it, then it's not natural and therefore evil (some people say).
Of course soil deposited in lowland areas is used for agriculture, and some civilizations like ancient Egypt depended on the annual fertilization carried in the sediment.
However, sediment can fill up reservoirs, interfere with water collection for cities, etc.. Don't know if this is a problem with this washout.
