Nutrient buildup describes the accumulation of certain nutrients such as Phosphorus (P) and Nitrogen (N). As a result, dredging is used to remove the excess sediment in order to restore the natural beauty of the lake. Siltation is typically caused by soil erosion or sediment spill. Siltation is when there is an excess amount of sediment buildup which can cause discolored, cloudy water. Lake dredging is typically performed due to siltation, nutrient buildup, and toxic contaminant problems found in the lake. Lake dredging is the process of removing sediment from freshwater lakes. Since large container ships carry the bulk of the world’s trade goods, marine dredging is widely considered a critical cog in the global economy. GPS positioning systems and slurry flow meters are typically used to ensure accuracy and optimal production rates. Canal management involves dredging sand from the ocean floor which ensures large ships can get pass safely without contacting the floor sediment. Over time, sediment builds up in harbors, canals, rivers, and lakes. Marine dredging also refers to harbor and canal management. Marine dredging is the most common way to excavate underwater. To be successful at marine construction, it requires the use of heavy-duty dredge pumps to efficiently remove sediment to ensure operation has a solid, even foundation on which to build from. Marine construction can describe a wide variety of structures that are typically built on the shore such as piers or seawalls or offshore as with oil rigs and cofferdams.
