Analisis Muka Air Banjir Sungai Tande Kabupaten Lingga Dengan Menggunakan Aplikasi Hec-Ras

---

ABSTRACT
Tande River is a river that flows in the Tande watershed which passes through
Daik Lingga Village, with a sub-watershed area of 765 ha. In general, the rivers
in Lingga Regency flow in hilly areas so that they are covered with forest plants
and during the rainy season there are frequent overflows of several rivers. For
this reason, as a river that has the potential to overflow, an analysis is carried out
regarding the capacity of the Tande River in various return times. The analysis of
the planned rainfall was calculated using the Pearson Log III method, with
rainfall data obtained from the Dabo Meteorological Station for a period of 11
years, starting from 2010 to 2020. The calculation of the planned discharge was
carried out at the return times of 1,0101, 1,25, 2, 5, 10, 25, 50, and 100 years with
the Synthetic Unit Hydrograph of Nakayasu method. Simulation of the water level
profile was carried out using the HEC-RAS application, and the calibration was
based on annual water level data obtained from BWSS4 at a flood discharge of
16,191 m3/s at a return period of 1,0101 years. From the results of running the
HEC-RAS version 4.1.0 program, it was found that the river overflowed at 1 point
cross section-D38-in the 1,25 year return period with 14 cm height, and increased
at other cross section with changes in the return period.
Keywords: Surface Profile, Tande River, Flood Discharge Plan, Surface Height, HEC-RAS.
