Abstract

This paper describes the 3D physical model for the proposed Hambantota harbour. The main objective of the physical model study is to assess the harbour tranquillity for different incident wave conditions which are expected to prevail at the site during harbour operations. It encompasses the assessment of wave disturbance within the harbour basin especially near the quay walls for assuring of safer ship motion and convenient ship operations and there by, to verify the adequacy and effectiveness of the harbour layout proposed for Hambantota harbour. The proposed harbour layout was subjected to several representative wave conditions in order to examine the wave penetration into the harbour basin and disturbance in front of the quay walls. In addition, movements of fully loaded ships were measured by mooring at various berth locations. Results for wave penetration were checked with mathematical model results. Ship motion results were compared with PIANC criteria. Both wave disturbance and ship motion results were within the acceptable limits.
