Turbidity currents are underwater density flows driven by the gravity-induced movement of sediment-laden water, which can reshape the seafloor and create geological features like submarine canyons and sedimentary deposits. These currents play a crucial role in sediment transport and deposition in marine environments, influencing both natural processes and human activities such as underwater cable placement and resource exploration.
Concept
Granular filtration is a water treatment process that involves passing water through a bed of granular material, such as sand or anthracite, to remove suspended solids and impurities. It is widely used in both drinking water and wastewater treatment due to its effectiveness in reducing turbidity and improving water quality.
