Evaluasi Rancangan Elevasi Tinggi Muka Air pada Jembatan Tol Sei Batang Serangan di Kawasan Sungai Sei Batang Serangan

Abstract

Hydrological analysis was carried out to determine the rain discharge that can be accommodated by the river with certain return periods and hydraulic analysis to determine the water level elevation which has an impact on the Toll Bridge that crosses the Sei Batang Panggang River. Therefore, this research was carried out to calculate the design flood discharge for return periods of 2, 5, 10, 25 and 50 years as well as the water level elevation on the Sei Batang Panggang Toll Bridge in the Sei Batang Panggang River Area. Based on hydraulic analysis using the HEC-RAS 5.0 program from steady flow data, the maximum water level elevation is 4.33 meters and the minimum water level elevation is 2.53 meters. In this way, the Sei Batang Panggang Toll Bridge area will not experience flooding because the water level elevation value does not exceed the flood water level
