Before finalizing the layout of breakwaters for a harbour, it is necessary to obtain an acceptable level of wave disturbance within the harbour basin. This is required to facilitate safe berthing of desired variety of ships in the harbour. Also, to address the problem of scarcity of land in highly populated coastal zones of India, it has been very important to mitigate the erosion at the shoreline. In view of this, it becomes necessary to predict the effect of coastal structures on shoreline and save usable land. In the present study, an attempt is made to check the effect of a proposed fishing harbour on the wave tranquillity inside the harbour and the probable effect on the shoreline due to littoral drift thereof. For this purpose, the site of Murdeshwar coast located by the side of a 500 m × 370 m normal headland at the central west coast of India is selected. The proposed fishing harbour consists of only one breakwater of length 820 m and width 120 m at the south side with an opening from westerly direction. Numerical modelling is done to arrive at erosion-accretion pattern on both sides of the proposed harbour over a period of 10 years. The wave tranquillity studies are conducted for assessment of wave tranquillity in the proposed harbour using MIKE 21 software. Littoral drift model used for the analysis of the shoreline changes determining the coastline position. According to the studies, the yearly net sediment transport is about 0.064 Mm3 from south to north direction and the gross transport is about of 0.178 Mm3. Numerical modelling revealed that the headland existing at the north of the harbour plays major role in tranquillity in the harbour basin as well as in establishing the shorelines at the site.
