Flood Hazard Mapping in Residential Area Using Hydrodynamic Model HEC-RAS 5.0

Abstract: The flood hazard rating is one of the essential variables in flood risk analysis. The identification of flood-prone areas urgently requires information about flood hazard zones. This research explains the method to develop flood hazard map by using hydrodynamic modeling in the residential areas. The hydrodynamic model used in this research is HEC-RAS 5.0, which can simulate the one- and two-dimensional flow regimes. The study area is Bukit Sejahtera and Tanjung Rawa residences located in Palembang City with a … Show more

“…Consequently, the discharge of liquid waste from these textile factories could potentially cause sedimentation in the upstream Citarum River that leads to a reduction of river capacity. The evaluation of a flood-prone area is a prior activity for mitigating flood damage [12]. This map will support the establishment of a strategy for managing the floodplain area and flood-affected areas based on current land use patterns, taking into consideration potential and natural factors.…”

“…In addition, in a 1D model, river bathymetry (bed topography) is represented by a series of cross-sections, which do not accurately depict the actual terrain. In a 2D model, however, this is represented by a continuous surface model, i.e., a finite element mesh, which more accurately depicts the actual topography [12,13]. Geoinformatics provides numerous tools for the study and visualization of temporal and spatial data.…”

“…Lebih lanjut disebutkan pula, bahwa banjir diakibatkan oleh faktor alam seperti curah hujan tinggi yang berlangsung lama, lokasi banjir terjadi pada topografi yang relatif datar, memiliki pola sungai berbelok-belok, keadaan struktur batuan yang lambat meresap, dan kapasitas sungai yang tidak dapat menampung serta mengalirkan air ke laut (Wahyuningtyas & Pratomo, 2015). Bagi daerah yang sering tergenang, kedalaman genangan banjir menentukan tingkat keparahan kerusakan struktur bangunan yang tergenang (Amin, Ilmiaty, & Marlina, 2020).…”
