Abstract:

The phenomenon of erosion and sedimentation have been classical issues for over a decade in the Bobuatan river. The two parameters that give a significant effect to the river morphology are river course and sediment. The last one has been the cause and effect of aggradation and degradation of the river bed, which leads to the catastrophe of construction along the Bobuatan river and its surroundings. This situation becomes an important thing to perform a study about the utilization of sediment material for morphology stability of Bobuaten river in East BolaangMongondow regency, Indonesia. This study aims to produce a method or recommendation to minimize the negative effects of sediment transport and inundation on geology and ecology disasters in the Bobuatan river. The procedures to perform analysis are begun with a survey to verify which method of analysis meets the existing condition in the Bobuatan river, followed by measurement and mapping of the Bobuatan river. With the collected data from surveying, analysis was conducted manually and with the aid of HEC-HMS and HEC-RAS to generate a real-time simulation of actual conditions in the study location. From the result of the analysis, the effect of utilization of sediment transport on the morphology stability of the Bobuatan river is predicted. Furthermore, the result will be a piece of vital information and basis to define the mechanism of water resource and environment management, as well as a recommendation to disaster mitigation.
