1.	Name the process of excavation activity usually carried underwater of purpose of gathering up bottom sediments.(a) Police drag(b) Dredging(c) Auger suction(d) Anti-eutrophicationI had been asked this question during an internship interview.I'd like to ask this question from Tidal Power topic in section Ocean Energy & Geothermal Energy of Energy Engineering
Answer» Right option is (B) Dredging The explanation is: Dredging is an excavation activity usually carried out underwater, in SHALLOW seas or freshwater areas with the purpose of gathering up bottom sediments and widening. This technique is often used to KEEP waterways NAVIGABLE and creates an anti sludge PATHWAY.
