High-Resolution Seismic Reflection Survey of Young Sediment at Can Gio Coast, Ho Chi Minh City, Vietnam

Young river sediment layers and seabed can be investigated by application of high-resolution seismic method supplied with a sub-bottom profiler. Contrast between different acoustic impedance leads to reflection of seismic waveform propagation that can image the interest geological targets. Soai Rap River is one of the two most important water gates in Ho Chi Minh city, Vietnam to the outside world. Studying its seabed and young sedimentology plays a vital in developing transportation and sea-ward economic Vietnamese policy. We have collected, processed, and interpreted ten of 2D high-resolution seismic profiles and two prior drill holes in the survey area, Can Gio district, Ho Chi Minh city. Its 3D seabed and 3D Holocene shallow sediment representations are interpolated different 2D boundaries which can be achieved by analysis of conventionally processed seismic data and seismic textural attributes (i.e., energy and entropy). Four resulted layers consists of water and young Holocene sediments and one trough channel in the middle of the river can be interpreted.
