Abstract

The Tidal wave is one of the main factors that producing sedimentary structure and agent of erosion. Study further about it can help for local people living in the coastal area and for academic learning. The tidal wave was replicated using a flume tank. The sand used is fine-grained that taken from Sawarna beach. To obtain the quantitative Digital Elevation Model (DEM) was used. The DEM data were taken using a laser distance meter after the experiment. Reynold's Rule was used for scaling down the variable that happens in nature to the experiment scale. There are 3 significant changes as a result of this experiment. First, the sediment was sorted according to the grain size of the sediment. Second, the slope of the coast has changed which is measured by DEM. Third, the sediment structure was created which has a similarity with the one created by nature. So, the result was a proof that Reynold's scaling down methods can be used to scale down a sedimentary process that happens in nature. This research explains what exactly happens in the formation of a sedimentary structure.
