Pond dredging refers to an excavation process done partly underwater in shallow water bodies. It entails removal and disposal of sediments and other deposits at the bottom of ponds. Apart from ponds, this process can also be done on shallow seas, lakes, rivers, and dams among others. There are several benefits and reasons for doing this process once in a while.
Some of the reasons of carrying out this process include making a water body navigable. Continuous deposition of sediments at the bottom of any water body reducing its depth, making it impossible for vessels to dock or move in them. On coastal lines, erosion carries away a lot of sand every time tides rise. Sand is replaced with other sediments that are not safe for coasts. This technique can be used to replenish sand.
Dredging is also helpful for making ponds more fit for raising fish. Sediment deposition decreases pond depths therefore making them not fit for inhabiting by some fish species. Sediments can also be dangerous to fish if they are made of harmful materials like aluminium and lead metals. Then lastly, dredging may also be applied as a fishing technique for some strains of edible clams and crabs.
A dredger is a universal term used to refer to any vessel, tool, or machine used to excavate sediment from the bottom of a water mass. Dredgers vary from simple handheld equipments to sophisticated cranes utilized to remove materials. The material extracted require to be disposed far from the water to prevent them from getting back into source easily. The sediments can be important as deposits on reclaimed lands. It however is good noting that this activity can cause some serious trouble in the aquatic ecosystem.
There are various methods of dredging consisting of suction, pneumatic, water injection, bed leveler, backhoe, snagboat, air-lift, amphibious, jet-lift, and clamshell among several others. In suction process, materials get sucked through long pipes. Its functioning resembles that of vacuum cleaners with the main difference being that this is done on very large scales. These sediments are eliminated through the other open end of the tube into a truck or trailer. This is the most prevalent kind of dredging in use currently.
In water injection dredging, tiny jets are utilized to introduce water under low pressure into the floor to make materials become suspended. These sediments then become turbidity currents, which flow down slope into other designated places. This skill is more appropriate if the pond is connected to another source of moving water.
Bucket dredgers have buckets attached on them for mechanically picking up sediment. There are usually several buckets attached on a wheel or chains and move in circular motion. Some models of these dredgers are powerful enough to be able to make a shipping track through coral reefs. Grab dredgers pick materials using a clam shell bucket from the base of the water. Clam shell buckets hang from crane barges or onboard cranes.
Pond dredging should be done occasionally. It is a healthy exercise and one should look for services of experts to perform it safely. Most firms charge depending on the measurements of the water body.
