Abstract
Floods during the rainy season has become routine events in several cities in Indonesia. Various reasons to trigger the occurrence of flooding, among other drainage network system capacity is decreased, increasing water flow, or a combination of both. The capacity of the drainage channel has been calculated based on the design criteria to accommodate the flow of water occurs so that the area is not experiencing inundation or flooding. The reduced system capacity due to, among others, many precipitates, physical damage or their network systems and illegal buildings on the system network. While the cause of the discharge increases, among others, high rainfall out of habit, changes in land-use, environmental damage to the basin in a region. Cases like mentioned above also occur in Sekanak Sub-basin, so it is necessary to study the drainage network performance evaluation system based on the concept of sustainable drainage based on community participation. One technical aspect is the frequency analysis to look at the picture unit hydrograph. Analytical results from this study may be that the maximum flow of 25 m3/sec at peak hours at the time of 4.8 hours and then slowly starting to go down at a time to 24 hours. Due to climate change impact on the water level at the mouth of the Musi river by 0.20 – 0.40 meters. Thin will also have an impact on the change of water level in the mouth of the Sekanak river. The total depth of water occurs at 15-30 meters and therefore contributes to the flow of the water fluctuation from Musi river to the Sekanak river.
