Near Field Physical Modelling of Malabar Deepwater Outfall

Ed Couriel

Open publisher page 0 citations

Abstract

Near field physical modelling of the Malabar deep water ocean outfall was undertaken because existing numerical models are unable to simulate the complex geometric and hydrodynamic detail of the outfall. Physical modelling was carried out at two different scales. A detailed local model was used to investigate the momentum dominant region, while a less detailed global model was used to study the buoyancy dominant region. The results of the study have shown effective behaviour of the outfalls with initial dilutions ranging from 200 to 800, depending on ambient conditions.
