Meander is a meandering river that occurs due to erosion and deposition. Morphology Meander
rivers are formed as a result of geological processes such as erosion, transportation and
sedimentation and result in the development of fluvial landforms. River meanders continue to
develop naturally which can change the morphology of the river through the process of denudation
that occurs along the river flow followed by the process of transporting sedimentary material and
when there is a decrease in energy, a sedimentation process occurs. This process produces a series
of loops along the watershed with different shapes, sizes and areas. This test was conducted to
determine the size of the grain diameter of the sediment in the sieve analysis and the pattern of
erosion and sedimentation in meandered river flows. The sample in this study used samples from
the Musi River area, precisely in Bailangu Village, Musi Banyuasi Regency. Thistest was carried
out in various stages with the location of the test being carried out at the Hydrology and Hydraulics
Laboratory of the University of Bina Darma Palembang. The test results were obtained. Based on
the results of the sieve analysis conducted at the Bina Darma laboratory, from six sediment samples
taken directly from the Musi River in Bailangu Village, Sekayu District, Musi Banyuasin Regency,
South Sumatra Province, then analyzed the average grain diameter is: D5 = 0.00; D35 = 0.40; D50
= 1.21; D65 = 2.00; D90 = 0.00 in millimeters. The sediment grains are fine sand and medium
sand. Meanwhile, erosion and sedimentation patterns produce a distribution pattern that results in
accumulation and scouring at each point.
