Dredging effects on marine environment

Ovaj rad opisuje postupak jaružanja, njegov utjecaj i načine za smanjenje utjecaja na morska staništa. Jaružanje je postupak kojim se iskopava nataloženi pijesak, šljunak, i mulj s dna rijeka, jezera ili mora, kao i transport i iskrcaj tog materijala na drugu lokaciju. Podvodni iskopi važan su aspekt kod izgradnje određenih ključnih elemenata infrastrukture određene luke. Jaružanje karakteriziraju tri operacije, to je uklanjanje materijala iz postojećeg okoliša, način uklanjanja materijala i bacanje neželjenog materijala u drugo okruženje. Jaružanje ima korisne, ali i štetne učinke. Kako bi se smanjila štetnost jaružanja potrebno je poduzimati sve preventivne mjere kako bi se smanjio utjecaj na morski okoliš. Primjenom odgovarajućih metoda u postupcima jaružanja može se dati prilično značajan doprinos zaustavljanju negativnih utjecaja na morski okoliš.This paper describes dredging process, its impact and ways to reduce impact on marine habitats. Dredging is the process of digging up deposited sand, gravel, and sludge from the bottom of a river, lake, or sea, as well as transporting and unloading that material to another location. Underwater excavations are an important aspect in the construction of certain key infrastructure elements of a particular port. Dredging is characterized by three operations, namely the removal of material from the existing environment, the method of removing material and throwing unwanted material into another environment. Dredging has beneficial but also harmful effects. In order to reduce the harmfulness of dredging, it is necessary to take all preventive measures to assure the least possible pollution. The application of appropriate methods in dredging procedures can make a significant contribution to stopping negative environmental impacts
