Abstract

Rivers bring organic and non-organic materials into the estuary, causing changes in the turbidity of the water. The hydrodynamic processes cause fresh water with different turbidity to be distributed towards the estuary, where it is trapped due to differences in the density of freshwater and seawater, forming a turbidity front (TF). The TF can be a trap of contaminated materials. However, it can be a reference for fishing areas due to the accumulation of nutrients. The study aims to analyze the hydrodynamic conditions and their effects on distribution patterns and turbidity front positions using 2D numerical models and remote sensing at Musi Banyuasin Estuary (MBE). Tides are dominant in controlling the flow and can determine the position of the TF. The verification value of the average relative error (MRE) of the model and in situ data is 30.74%. Landsat image analysis confirmed by the turbidity model shows that the TF formed in the turbidity range of 40-50 FTU. Model simulation results and images were directly proportional; the furthest distance where TF formed was at the lowest ebb in neap tide, 14.87 km (model) and 15.56 km (satellite). The correlation between satellite data and the turbidity model was validated with r≥0.5.
