Coastal Water Properties and Hydrodynamic Processes in the Malacca Strait: Case Study Northeastern Coast of Sumatra, Indonesia

Dynamic processes in the coastal waters play an important role in regulating marine pollution distribution caused by riverine inputs and are relevant for coastal management. Here we investigate the coastal water properties from field measurements and modeling hydrodynamic processes in the northeaste...
