TL;DR: In this article, the seasonal and tidal changes in flow and suspended matter dynamics in the tropical and macrotidal Van Uc River estuary (North Vietnam) were explored, among others, the sediment delivery to the ocean and the processes behind the estuarine siltation.

TL;DR: Wang et al. as discussed by the authors developed a 3D numerical model of multifraction sediment transport based on the coupling of modified EFDC model and SWAN model to investigate the sediment transport.
Abstract: Huanghua Harbor, located in the south-west coast of Bohai Bay, China, has frequently encountered severe channel siltation with sorting sedimentation along the channel during storm events since its construction. For prediction of channel siltation, a 3D numerical model of multi-fraction sediment transport based on the coupling of modified EFDC model and SWAN model is developed to investigate the sediment transport. It is shown from simulated results that the sorted sedimentation in the channel was well simulated in storm events, and the high sediment concentration near sea bed for silty coast during storm process can also be basically reflected by the model.

TL;DR: In this article, the ebb water and sediment diversion ratios and the net discharge water/sediment diversion ratios in the Changjiang River estuary area were calculated by using the hydrographic data observed in the area in September, 2002 and the standard hydrodynamic method.

TL;DR: In this article , the authors collected hydrographic survey charts of Pussur River from Mongla Port Authority (MPA) and analyzed to assess the trends of morphological changes at the potential sites.
Abstract: Mongla Port is the second gateway of Bangladesh, situated at the bank of the Pussur River some 131 km upstream from the Bay of Bengal. In this study, the available hydrographic survey charts of Pussur River were collected from Mongla Port Authority (MPA) and analyzed to assess the trends of morphological changes at the potential sites. The causes of navigation problems, previous interventions of MPA, dredging history of the river, and effectiveness of dredging was analyzed. It is found that in the upstream portion of the navigation route at the MPA jetty area and its approaches was slightly scour-prone from 2010 to 2013; however, after capital dredging in 2014, the channel was found highly siltation-prone, having a rate of 0.1–0.6 m/year between 2015 and 2017. Before dredging the channel, the Inner bar area (downstream of Mongla Port) did not show any significant change in the bed topography between 2010 and 2013, however, a high backfilling rate (up to 1.5 m/year) was observed after the capital dredging. The channel was sufficiently deep and quite stable from Joymonirgol to Hiron point. The current navigational channel at the outer bar (at the mouth of the river) is silted by 0.1–0.25 m/year. Reduction of upstream flow, numerous shipwrecks at different positions, and human disturbances were identified as the causes behind the navigational problems in the river route.
