Analisis Profil Muka Air Sungai Daik Menggunakan Hec Ras
ABSTRACT
Daik River in Lingga Regency is one of the rivers prone to floods. To overcome
the flooding problem, information is needed about the depth of the flood and the
points where the location is prone to flooding. Therefore simulating a water level
profile aims to provide information about the depth of floods and flood-prone
points on the Daik River in Lingga Regency. Water level profile simulation
modeling uses HEC-RAS software. The design flood discharge is calculated with
a return period of 2 years, 5 years, 10 years, 20 years, 25 years, 50 years and 100
years using the methode HSS Nakayasu. The boundary condition in the upstream
part is the design discharge and in the downstream part is the Known Water
Surfaces with a water level of 3,55 m. The simulation results show that in most
parts of the Daik River at the time of the return of 10 years there has been a flood
inundation with an flood discharge of 64,995 m3/s
Keywords:Daik River, Water level profile simulation, HEC-RAS.
