EVALUATION OF DRAINAGE CHANNEL CAPACITY ON JALAN BUDI KARYA, PONTIANAK SELATAN SUB-DISTRICT

Drainage is one of the most critical components to be maintained and developed in a strategically healthy comfortable urban environment. There are often puddles water on Budi Karya Street, especially at Permai Reservoir Complex. In solving existing inundation problem, primary secondary data needed. Primary form longitudinal transverse sections channel, while location maps, tidal data, rainfall used analyze hydrology. Based analysis capacity Karya's drainage channel using HEC -RAS software as flow modeling tool view level profile along perspective drawing, or hydrograph, it was found that could not accommodate planned discharge for return periods 2 5 Year. Therefore, necessary improve normalization channels.
