| Summary: | Flooding is a natural phenomenon that has a significant impact on urban areas and
communities. One area that frequently experiences flooding is the Cinambo River
Basin, particularly in the Pasar Gedebage area of Bandung City. This study aims
to propose solutions to reduce flood water surface elevation in the region. A
hydrological analysis was conducted to obtain the 5-year return period design
discharge using the Synthetic Unit Hydrograph (SUH) SCS method, processed
through HEC-HMS. A hydraulic analysis was then performed using HEC-RAS to
simulate water inundation during floods and to design flood control structures. The
proposed solutions include river normalization and the construction of parapet
levees along the riverbanks, with an additional alternative of a retention pond.
Stability checks were conducted, and it was found that the design meets the
minimum safety factor requirements. The total cost for the proposed flood control
plan in the study area is Rp7,808,761,000.00. |
