The Effect of River Meanders on River Morphology

Abstract

Meander is a change in the flow of a river that forms a Semicircle or like the letter S whose fingers are irregular or irregular due to horizontal and centrifugal pressure. One of them that has a meander river is in citarum watershed, located in Majalaya Sub-district, Kab. Bandung. There is a change in the morphology of the river so that the geometry of the river changes from its original shape. The purpose and purpose of the Research to analyze the value of speed, meander fingers, and the morphological influence of rivers so that the problems that arise can be reduced and the benefits/potential possessed can be optimized. The research method used comparative causal methods (causal relationships). The results suggest meander river like the letter S is quite Ideal. Materials along the meander section contain clay, gravel, sand and macaques, clay stones and ash and black stones. Meander River with a length of ± 975 m is divided into five segments, namely. It was then concluded that V<, Q< → Rc > and V>, Q> → Rc < as well as morphological types A, E, G, F & DA.
