What is dredging?
excavating is a process that includes water excavations of water beds to remove sediments, pollutants, molluscs and other materials. Methods and machines used in dredging are very different. Most excavations are done by ships that pull the excavator along the water bed. For routine tasks, separate excavating and petrol stations are used. A excavator, which is a catch of the whole term for different types of machines that perform excavating, can cut off the sediment, recruit materials such as the rear hoes, or suck them through a large tube to be placed in a boat, boats or other containment system. Pass. Over time, the waterway is filled with mud and sediment that require relatively general maintenance to be effective. There is also a demand for constantly expanding markets for the creation of new waterways.
2) is used to excavate seafood . This type of dredging involves dragging a metal net along the bottom of the ocean DNA or other large watersy to catch animals like crabs, fish and octopus. In this way, the removal of pollutants often causes other environmental problems, such as the destruction of habitats of important plant and animals.
4) Dredging can be used to remove the desired water bed materials such as minerals. It can also be used to restore land by throwing out dredged sediments on the ground that was lost at sea, as in the case of the Gulf Coast in the United States. Similarly, some beaches are maintained in this way by collecting coastal sand and redistribution along beach.
Bagriing represents many environmental problems. A problem where the mined material will be destroyed. The material is often thrown into the mouth of rivers, which are shallow entrances of the sea or mouth of the river. The ejection at the mouth of the rivers can lead to floods and destruction of rich habitats. In the United States were according to the lawAnd the net water developed by laws to keep dredging activities under control and minimize environmental consequences. Since the environmental effects are obvious, the excavator industry works to improve machines and excavating processes using alternative methods, if possible.
