The city of Lhokseumawe often experiences flooding or stagnant rainwater. The Pusong Reservoir that was built could have been ineffective in overcoming the flooding problem due to siltation in the reservoir. Therefore, this study aims to review and recommend the management of the Pusong Reservoir based on suspended sediment discharge which is expected to overcome the silting problem of the reservoir. The sampling method was carried out by determining the stations for sampling based on the environmental baseline in determining the six reservation stations. Samples were analyzed for suspended sediment concentration, turbidity, and incoming sediment discharge. Analysis of suspended sediment concentrations ranged from 9.3 - 50.0 ppm, turbidity ranged from 2.17 - 14.42 NTU, and the incoming suspended sediment discharge was 0.00 - 6946.56 kg/day. Based on the analysis of suspended sediment discharge that enters the reservoir, it is necessary to control sediment transport to prevent siltation does not occur in the Pusong Reservoir. The management of the sediment transport control includes sediment traps, vegetative systems, and Spoil Bank Resulting from Sediment Dredging.Keywords: Suspended Sediment, Management, Pusong Reservoir, Turbidity

The Day estuary area is accreting relatively quickly, expanding the land area for Nam Dinh and Ninh Binh provinces. To understand the sediment accreting mechanism in this region, 42 surficial sediment samples were taken and analyzed for grain size to determine the rules of surficial sediment distribution and analyze the net sediment transport pattern. Research result shows that in the Day estuary area: sand is mainly dominated in the east and south, silty sand is distributed in front of the estuary and south of Con Noi, and sandy silt is distributed in the west and center of the study area. The coarsest-grained sediments are distributed in the North and South, while finer-grained sediments occupy the main area in the East and finest-grained sediments are spread out in the West of the study area. Well-sorted sediments are dominated throughout the region, covering the center and the East of the study area, showing that the hydrodynamic regime is relatively stable. Medium-sorted sediments are distributed in the West, North, and South, reflecting a less stable hydrodynamic regime. Poorly-sorted sediments at the Day estuary mouth represent the most complex hydrodynamic conditions here. Sediment tends to be transported from the southeast and west to the central area, causing a strong accretion process to create Con Noi and shallow mild tidal flats in the Day estuary area.
