Abstract
- The Dong-Sam seawater stream flows within a seaside landfill providing waterfront areas for both people and marine lives. However, sewage and pollutants from nearby residential and industrial areas are being deposited due to slow flows. To improve water qualities by increasing flow velocities, this study conducted field observations using Aquadrifter and a Computational Fluid Dynamics (CFD) analysis in a total of six scenarios. The field observations show that the maximum velocities of 0.13 and 0.11 m/s occurred at the two ends of the stream, whereas flows were weakest in the central portion of the stream. In these circumstances, the scenario (Case III-b) for emplacing two sluice gates each at either stream end performs best to achieve the goal, increasing flow velocities. Case III-b scenario results in the increase of flow velocities in all the points in the model, even at the center area of the Dong-Sam seawater stream.
