Analisis Sistem Drainase di Kawasan Pemukiman pada SubDAS Aur Palembang (Studi Kasus : Pemukiman 9/10 Ulu)
Abstrak: One of the area in
Palembang City that often floods is 9/10 ulu residential on sub DAS Aur.
Existing drainage channels have dimensions that are not sufficient to flow peak
dischange caused by storm and tides. Therefore, it is necessary to study the
drainage channels in the residential areas. The first stage in the analysis
begins with hydrologic analysis to calculate the distribution of rainfall using
maximum daily rainfall data for 20 years from 1993 to 2012. The next step
calculates the design rainfall intensity, then calculate the design rainfall
hyetograph using ABM method (Alternating Block Method). By using SWMM 5.0
(Storm Water Management Model 5.0) program can analyze the available drainage
system in the residence, then the input data was complete. Floods simulation
about the improper water drainage can be achieved after inputting the data.
Redesigning the rational method and simulated by SWMM 5.0 program to replace
the previous channel dimensions and dimensional data input channels planned,
then the simulation results with good water flow in the channel was ideal.
