Impacts of breakwater to navigation at Sungai Terengganu river mouth

Abstract

The construction of breakwater at Sungai Terengganu river mouth has result the navigation channel to shallow and narrowed. In this study, the impacts and risks of construction of breakwater towards vessels navigation are investigated through risk management and risk assessment approaches. The risk assessment are accomplished through historical marine accident analysis and sampling to the breakwater users which the level of impacts towards navigational defects before and after the construction of breakwaters are essentially studied. The probabilistic risk assessment includes the calculation of occurrence probability of the impacts. Analyses of the impacts of breakwater construction to navigation at Sungai Terengganu river mouth has investigate the major factors contribute to the impacts upon the construction of breakwater and reviewed by diagrammatic logic of qualitative risk assessment. The preliminary results of the study expected the improvement of navigation safety with minimum impact reflected. The study also presents the recommendations for improvement of navigation safety of while reduced the possible reflected impact.
