INFLUENCE OF SALINITY LEVELS ANALYSIS ON SETTLING VELOCITY OF FINE SEDIMENT GRAINS IN CILIWUNG ESTUARY

Transport of estuarine sediment have a highly complex method, which is the combined effects result periodically reciprocating flow, ocean waves, and electrochemical characteristic sea water [1]. Settling velocity (SV) such parameter fundamental for researchers so that its accurate resolution has been regarded as top priority in correcting modelling numerical conceptual understanding fine dynamics [2] [3]. The goal this study to analyze effect salinity levels on settling grains Ciliwung estuary, Jakarta. method used direct measurement using hydrometer analysis method. experiment shows affect estuary. higher salinity, more faster grains. average at distilled 0 ppt 1.083 mm/minute, with 0.3 1.537 0.6 1.561 mm/minute.
