There are different sources that cause pollution which are sewer overflows, municipal and industrial discharges, and spills. Dredging helps to correct the damage caused by adverse weather conditions and increasing climate changes. Many cities affected by exposure to rising sea levels and storm damages require dredging for reclamation. Dredges are vital to port maintenance.
