Abstract

BThis study was conducted to determine how the existing drainage system is already optimal and how the capacity of the existing channels are still adequate or not. In practical analysis of hydrology and hydraulics. Hydrological analysis using the data after the maximum rainfall was measured dispersion through the calculation of statistical parameters. Followed by choosing the type of distribution to get a way to process data rainfall measurement and calculation of rainfall intensity plan. Analissis hydraulics drainage discharge capacity of the existing form, after it created the system and the appropriate dimensions. The results based on measurements obtained dispersion suitable distribution is the distribution of Log Pearson III and precipitation values obtained plans for a return period of 2 years at 101.7983739 mm watershed drainage coefficient obtained at 0.8961 with a basin area 501.32 m2. Values rain discharge for return period of 2 years with a rational method obtained value 2.1172 m3 / sec. Qhujan value is 2.1172 m3 / sec while the value Qteoritis is 0.0833 m3 / sec. Because Qhujan larger than Qteoritis, it can be concluded that the existing drainage channels is not enough anymore to accommodate the existing flood discharge. Keywords: drainage, hydrology analysis, hydraulics analysis, distribution log pearson III, drainage coefficient, discharge.
