Abstract

This paper presents an example of sediment infill evaluation of navigation channel during dredging work. Matarbari Ultra Super Critical Coal-Fired power project, which includes the dredging of a 14 km long navigation channel, is currently in progress on the southeast part of Bangladesh. Due to high-turbid water on the coastal area of Bangladesh, it is concerned that the dredging volume might be extremely large. To evaluate the sedimentation of the channel before starting the work, this study investigates the characteristics of the physical systems in the project area based on data collection of wave, tidal currents, seabed materials, etc. The simulation model was developed and validated by comparing with bathymetry survey result. The validated numerical model was then applied to estimate the sedimentation volume in 3 years after the future channel dredging works. Numerical tests clarified that additional dredging volume increases due to the delay on the construction schedule of the sedimentation control bund.
