Popis: High rainfall rate in Indonesia makes the outcrop located in the upstream areas easily eroded and some rocks carried by the water flow towards the downstream areas. This research is done in order to identify the silting of Cikapundung’s River in Bandung. The method used is 2D resistivity method for mapping sedimentation of Cikapundung’s River. The data was taken in KampungPadi Residence, Cisitu, Bandung, West Java. Geological observation’s results show that top layer consists of alluvial’s sedimentation, basalt tuff, and volcanic conglomerate. Basement of river’s flow is volcanic conglomerate which has eroded and sedimentation. Discussion’s results show that Cikapundung’s river has sedimentation’s thickness until 16,4m. This sedimentation consists of top soil and conglomerate rocks. Furthermore, from data processing’s result there is an indication that ancient Cikapundung’s river, in meander section which have low energy value and then eroded resulting in a shift of the river’s flow to the south.
