River Dredging Machines

Every year the need for river dredging increases around the world. Communities that surround the natural flow of a river are susceptible to annual flooding during the rainy season. If the river is not properly maintained, silt, sand, and debris can accumulate and form a bottleneck. If a major rain event occurs, the bottleneck will restrict flow and the river will rise above its banks and flood local businesses and dwellings, causing millions of dollars in property damage and possible loss of life. River dredging equipment is necessary to maintain the natural flow of rivers and limit the potential for disaster. Using a river dredging machine ensures that the riverbed is clear of obstructions, reducing the risk of flooding.

Versi-Dredge Capabilities

The Versi-Dredge has been utilized for various river dredging activities around the globe, including flood mitigation, sand mining, navigation channel deepening, and environmental dredging. The Versi-Dredge’s one-truck transportable design allows municipal governments and contractors to quickly deploy the dredge to a trouble spot and open it up to maintain proper depth and hydraulic flow. The dredge can then easily be removed by a single crane and stored off site until it is needed for river maintenance again.

In the case of environmental dredging, the Versi-Dredge can be outfitted with a customized pump that can cut and pump cans, bottles, plastic bags, ropes, rice sacks, etc. without clogging like normal hydraulic dredges do. This allows operators to remove silt and mud from rivers where dense populations have used the river as a trash can.

In the case of pollution clean-up, the Versi-Dredge can be put into cable drive mode and a GPS system and environmental cutterhead can perform surgical dredging in a precision grid format to remove layers of contaminated materials from rivers and pump them to a water treatment plant on shore.

Brunei Receives A Dredger To Control Flooding

Brunei might have just found a solution to “better control” flood situations, as a new, efficient and economical dredge has arrived in the Sultanate to deepen and de-silt rivers, lakes, coastal areas and marinas.

Frequently Asked Questions

Why is river dredging necessary for flood control?

River dredging is essential for flood control because silt, sand and debris build up over time and narrow the channel, reducing its capacity to carry high flows. Removing that sediment restores the river’s cross-section so floodwaters pass safely instead of overtopping banks and damaging property. IMS Versi-Dredges are used in flood-mitigation programs worldwide, from the Philippines Department of Public Works and Highways to FEMA-funded channel work in Iowa. Regular maintenance dredging is a proven way to reduce flood risk.

What machine is used to dredge a river or channel?

Rivers and channels are dredged with a hydraulic dredge that cuts and pumps sediment as a slurry to a disposal or reuse area. IMS one-truck transportable, self-propelled Versi-Dredges are widely used for channel maintenance and flood prevention — commonly the high-production 7012 HP on larger rivers, with the 5012 LP and 5012 HP on smaller ones. IMS units work on rivers including the Tigris and Euphrates in Iraq, the Niger, the Thames and the Marikina in the Philippines. The model is matched to the river’s depth, flow and material.

How does river dredging remove silt, sand and debris?

A hydraulic river dredge uses a rotating SolidsMaster® horizontal auger cutterhead to loosen compacted silt, sand and debris, which the ladder-mounted pump then lifts and moves through a pipeline as a slurry to a spoil area. The enclosed auger removes material continuously and cleanly with low turbidity compared with mechanical methods. The cutterhead is selected for the river’s material.

Can a river dredge operate in high-flow or very shallow rivers?

Yes. IMS self-propelled dredges are designed for challenging rivers — patented Starwheel Drive® with TractionMaster® technology gives traction and control in current, and shallow-draft configurations let them work in low water. A secondary cable-drive system is included as standard for situations where it is preferred. For high-flow conditions IMS typically recommends the powerful 7012 HP. The configuration is matched to your river’s flow and depth.

What size river dredge do I need for my channel maintenance project?

The right river dredge depends on channel width and depth, flow conditions, the material (silt, sand or gravel) and how far you must pump. For higher-flow rivers and channel maintenance IMS commonly recommends the high-production 7012 HP, while smaller rivers and canals suit the 5012 LP or 5012 HP. Share your river’s depth, flow and length and IMS will match the right model and cutterhead.

How is dredged river material disposed of or beneficially reused?

Dredged river material is pumped to a designated spoil or containment area where it dewaters — often into geotextile tubes — and clean sand and sediment can frequently be beneficially reused for fill, bank building or aggregate, while unsuitable material is disposed of per permit. IMS supplies discharge accessories such as the Broadcaster attachment to place material where you need it. Planning the spoil area and reuse options early keeps the project efficient and compliant.
