Analysis of Breakwater Construction Effects on Sedimentation Pattern

A. Vaselali and S.A. Azarmsa

Sediment transport driven by current, wind and wave plays an important role in influencing the evolution of offshore and onshore bed morphologies by deposition and erosion. Correspondingly, the offshore and onshore industrial devices may be seriously damaged in some extremely cases like typhoons, hurricanes and so on. Therefore, one of the most important issues for coastal engineering is suitable structure layout. Also, the study on sediment transport phenomena under various environmental conditions is an important subject to both coastal engineers and researchers. Fishing port of Pozm located in the Northern part of the Oman Sea involved in sedimentation predicament, so that to difficult correct exploitation of this in practice. A new breakwater was constructed in the West to East direction, perpendicular to a former breakwater, in order to solve a sedimentation problem in the Pozm Fishing Port. In this study, sediment movement has been studied using a numerical model in Pozm Bay. Sediment transport caused longshore currents are simulated, before and after construction of the new breakwater, with MIKE21 non-cohesive sediment transport module (ST). The model was calibrated by use of a combination of field data and calibration parameters derived from existing literature. The model reproduced the hydrodynamics satisfactorily as well as the concentration level and variation of non-cohesive sediment transport. Results of this study anticipate that sediment settlement around the newly constructed breakwater occurs and problems like those investigated near the North-South breakwater may be repeatedly observed for the east-west breakwater, too.
