One of the reasons that encourage individuals to invest in homes next to shores near lakes, rivers, and ponds is the view and environment. But due to constant rainstorms the loose top soil is washed into the nearest big body of water which then starts filling slowly with sediment making waters unsafe for use for swimming, sailing and a myriad of other activities. Weeds can also cause clogging up of water rendering it to look more like a swamp this can seriously affect the aquatic life making it no longer sustainable and in the end will require lake dredging.
Some of the stuff that make for unhealthy waterways include sludge, sand, sediment, and muck that can be quite hazardous to the surrounding community. Sitting on the bed of water body, these materials slowly lose oxygen that was locked in the end beneficial microorganisms eventually die. This makes the waters to produce a smell akin to a rotten egg as well as an unpleasant discoloration.
Two main types of buildup affect all categories of waterways these are vegetation and sediment. Vegetation grows to clog up the area in the form of weeds one of the most common is the hyacinth that slowly allows sediment to build up. Sediment on the other hand starts at one or more entry points and slowly seeping into the water body downstream containing soil, rocks and other materials washed off the land.
There are three types of dredge techniques and these are hydraulic, diver assisted and mechanical methods. Diver assisted methods require an individual to go to the bottom of the lakes with a special suction pump while the hydraulic uses a temporary pipe line to an offshore location. Mechanical uses excavators or draglines that have a long reach and best suited shallow water.
Before carrying out the process, it is vital that a study of the bed is carried out through a method name bathymetry. It uses a three dimensional mapping system that can accurately helps the expert to understand the setup of the bottom of a pond. Identification of the deep and shallow points is achieved easily aiding in the calculation of rate of sedimentation.
The process is also particularly helpful in creating waterways to allow big boats to go through easily and especially now that there is a huge demand for alternative transportation. Other applications include capturing aquatic life forms from the bottom of lakes like squid, fish, and crabs. Some companies and individuals use the process to get minerals from the seabeds and shallow ends of the waters.
Nevertheless, the numerous advantages of this process have a negative effect on the ecosystem that has been established by marine life disrupting it in a large part. It is also during the process that heavy metals are unsettled from the safe positions to unsafe locations. It has also been observed that it acts as a disruption of the migratory paths and schedules of aquatic life forms.
If considering lake dredging it is important that one should consult with the local authorities for further information. In the United States, a clean water act was implemented to control the use of this process in an effort to reduce the damage caused to the environment by it. At the same time, many firms are working together with communities to create improved machinery and methods of carrying out the process.
