WATER INJECTION DREDGING:
dredging the natural way
The Water Injection Dredging is a simple concept and natural which eliminates the need for mechanical dredging and transport of the material with the consequential related matters of costs linked to these items. This method whereby the transport material occurs horizontally is respecting more the environmental restrictions then any other dredging technique inclusive the hydrodinamic techniques.
It is a method of dredging where a big quantity of water at low pressure is being introduced in to the sediments, utilizing pumps which inject water by means of a horizontal pipe with a range of diffusers. This water changes the density of the sediment layer in such a way that it becomes and starts to behave as a fluid . At this point the gravity and/or the currents move the material outside the dredging area without a vertical transport taking place with the sediment.
