==General description==

Many human activities (e.g. farming, forestry, road construction) can cause erosion in catchment areas that often cause sediment runoff. Mining operations directly or through escapes in their settling ponds often produce sediment discharges to the river.
Also, directly dredging operations on rivers release suspended sediment into the water
column by agitation of the bed and by discharging overflow slurries. There are four
reasons for undertaking dredging works: flood alleviation, land drainage improvement,
navigation and gravel and sand mining. In all cases the effect is to increase the river
channel capacity and thus its ability to convey water.
