Abstract
The Wedung waters exhibit a relatively elevated sedimentation rate. This occurrence can be attributed to the substantial quantity of sediment deposited in these waters by various river estuaries, such as the Jajar, Gojoyo, and Saklenting Rivers. The estuarine environment, serving as a transitional zone between fluvial and marine systems, exhibits a propensity for sediment accumulation due to the confluence of riverine and marine sediment, leading to the phenomenon of siltation. The objective of this investigation was to ascertain the properties and spatial arrangement of sedimentary deposits located at Wedung Waters, Demak. The parameters that were examined encompassed bed load sediment, currents, tides, and bathymetry. The employed techniques encompass dry and wet sieving methodologies, cartographic representation through ArcGIS 10.3, and simulation via MIKE 21. The findings of this investigation suggest that the sediment distribution comprises a combination of silt and sand. The present velocity spectrum, including tidal currents, spans from 0.000029 to 0.086279 meters per second. The bathymetry conditions exhibit a sloping topography, characterized by a depth range of 0 to 30 meters.
