Field measurements and numerical modeling of nearshore processes at an open coast port on the east coast of India

Port development and associated constructions such as groins, jetties, breakwaters along the shore front alter the coastal environment considerably. Gopalpur (19°18′13″ N : 84°57′ 52″ E), a seasonal port along east coast of India is under phases of development to an all weather open coast port and has a significant impact on the coast. Field data collected on beach morphology, waves, tides and currents at seasonal and annual basis for two years are analyzed. Numerical modeling of hydrodynamic, wave, sediment transport and shoreline evolution using DHI-Mike models are carried out. Present study describes the field data, the hydrodynamics, wave induced sediment transport and the nearshore circulation pattern suggesting an appropriate management plan.
