Description 1255-1263
A two-dimensional finite element numerical model has been developed to simulate tide and wave characteristics for Maharashtra coastal region, India. The region was divided into four zones based on water depth and the Chezy’s friction co- efficient values for each zone were determined. It was noticed that as the water depth decreases the values of friction co- efficient increases. Results are validated with observed tidal elevations, currents and significant wave height at various locations. Prediction of the amplitude and phase of tides showed good agreement in most locations. Trends of the variation of wave heights with distance from the coast appears to be similar along different sections along the coastline, however, the wave heights at any particular location is observed to be function of local water depths. Hydrodynamic modeling setup forms a base for modeling of various coastal process and man-made disaster such as oil spill, in future.
