Coastal regions are among the most important places for urban development and industrial expansion.However, the system is active and it must be well examined before any infrastructure is planned, to avoidharm from natural processes like degradation, sedimentation, and sometimes sea-generated naturaldisasters. Numerical modelling of the coast to forecast the area’s natural parameters is an importanttechnique for assessing these systems. Coastal regions are of critical importance to most of the world’scitizens with a significant bearing on economic activities. In the present study, a well-calibratedmathematical model of Vengurla, Maharashtra, has been developed using MIKE 21 flexible meshsoftware, with the latest prototype data and also carried out 2-D hydrodynamic studies for the proposed500m breakwater and approach channel. The simulated model will be tangled with the sediment transportmodel to ascertain the likely pattern of siltation in the area. After studying the Hydrodynamic model, itwas observed that in existing conditions, currents varied in the range of 0-0.02 m/sec inside the Vengurlacreek and 0-0.15 m/sec in the seawater and currents under the proposed condition varied in the range of 0-0.029 m/sec inside the Vengurla creek and 0-0.22 m/sec in the seawater. No severe circulation or eddieswere observed near the beach area in the existing condition as well as in the proposed condition, hence nosiltation has occurred in that area. From the sediment model, it was observed that there is not muchsiltation/erosion after the construction of the proposed breakwater and deepening of the approach channel.
