【 摘 要 】

Multitude numbers of bridges and barrages are being constructed across innumerable rivers in Indonesia to serve different purposes for the benefit of people. However, some of these bridges are failed due to channel bed degradation and scouring. Bridge scour is one of the main causes of bridge failure. To prevent this condition, it is very crucial to thoroughly understanding the river behavior changes at the upstream and downstream area of bridge and barrage constructions. After that, the proper operation and preventive maintenance of bridges and barrages can be formulated. In this study, we identified the indicator parameters that are associated with hydraulic channel and potentially scour the bridge. The objective of this study is to develop a scouring assessment based on the river flow regime. In the assessment, the structures is the indicators status and the performance of the bridge component which will be measured in order to assess the bridge failures performance, and recommendations are proposed to obtain the results by using visual inspection method. The assessment models is an evaluation of the river regime condition using inspection and other direct measures to determine the effect of river condition related with deterioration. The study result shows that the main component to assess the performance of bridge are hydraulic channel, riverbank, and floodplain. The assessment is conducted at the upstream and downstream area of the bridge.
