Abstract

This study uses the Duboy's method and the Englund -Hunsen method to calculate bed load transport which aims to determine the volume of sedimentation in the Cileueur River, Ciamis Regency as a form of early anticipation of disaster risk.This research was carried out with stages starting from hydrological analysis, determining the planned rainfall, analyzing the design discharge, and analyzing the average velocity of the river.This research is based on considerations to anticipate disaster risks, especially in the Cileueur River, Ciamis Regency, this river has a length of 25,000 m and an area of 13,660.7 ha of watershed. In the Cileueur River there are several problems including silting of the river which results in frequent occurrence of large enough water overflows exceeding the cross-sectional area capacity of the river during the rainy season. Seeing the impact of the occurrence of these problems, it is necessary to conduct research in order to anticipate risks before a disaster occurs.Based on the results of the analysis and discussion, it can be concluded that the results of bed load transport calculations in the Cileueur river, Ciamis Regency using the Duboy's method obtained an average of 357.5619 tonnes/year and the Englund and Hunsen method of 317.379 tonnes/year. Then the comparison of the results of calculating the amount of bottom sediment from the two methods is 6%.
