| Summary: | Analysis of Hydrology and hydraulics on the design of Kayu Tanam – Padang Panjang – Batu Tabal km 71+075 railway bridges is important. This is to determine the safety of the bridge against the flood in return period 50 years and the safety of the bridge structure to the river flow that across the bridge. The steps in this study are hydrological analysis to determine flood flow, hydraulics analysis to determine flood water level and flow velocity, and design of river control building that is retaining wall and groundsill . The area of the watershed with the outlet point bridge is 8.8 km2 and slope 23%. In this study the result of the flood water level is 2.9 m from the bottom river while the hight of the pier is 8.4 m and 9.5 m so the bridge safe from the flood plans. The retaining wall as a river bank protector is designed with width 4 m and height 3.9 m. Groundsill as sediment control designed with is designed with the height of main dam 3 m. |
