Type of dredging projects - maintaining navigation channels and harbours

What are the types of dredging projects? This section are going to show four main types of dredging project which are also conducted on the dredging sites. Dredging activities do sometimes fall into more than one of the categories described.China Do Pump is a maunufacturer of dredging equipment, including sand dredge pump, cutter suction dredger, jet suction dredger, TSHD, dredger cutter, floater and pipe in China. The purpose of types of dredging projects is not to give an exhaustive classification of projects, dredging projects characteristics and ralated problems. 

Type of dredging projects - maintaining navigation channels and harbours

Most harbours and navigation channels are quiescent artificial depressions. The maintaining navigation channels and harbours project involves the removal of relatively recent, generally fine-grained sediment, coarser mateirlas, such as sand, gravel in shipping channel. Suspended solids settle there and tend to restore the original profile of the riverbed. The purpose of maintenance dredging is to remove such sediment to ensure safe depths for navigation. 

The maintenance dredging generally poses the greatest risks for the environment because of its periodic nature and the risks of pollution, the sediment removed must also be disposed of. 

On the other hand, maintenance dredging is performed at sites with a well-defined purpose, sites where navigational activities generally prohibit maintenance or exploitation of biological or recreational potential. Maintenance dredging is therefore unlikely to interfere with other uses of the dredging site, and environment impacts are mainly related to the disposal of dredged material.
