Komering river is a river with huge potential as flooded control. While definition of the estuary of the river downstream of the river is directly related to the sea , the river serves as the expenditure (Triatmodjo, 1999). The water of this river carries sediment transport which is accumulate in the estuary. The main purpose of this study is to analyze the value of sediment load in the estuary…
Siltation occurs because the river is due to several factors, among others : its High erosion in upstream, which resulted in the deposition of sediment transport in estuaries, tidal and river sedimentation due. In general, due to the silting of the river sediment occurs because sendimen transported by water is no longer carried away by the water, this occurs when the velocity of the water decre…
Gate are much used in irrigation canals to regulated distribution of water to water-using farmers and are aJso used for dnnking water processing plants.
