ANALISA KELAYAKAN DRAINASE DIDEPAN CITI MALL KECAMATAN BATURAJA TIMUR KABUPATEN OGAN KOMERING ULU

Abstract

In solving an existing inundation problem, maximum rainfall data, population data, and hydraulics data (observation) are needed. The following is the maximum daily rainfall data followed by the calculation of the rainfall intensity. Next with the calculation of the standard deviation to obtain the calculation of the birthday period using the Pearson Type III method. From the results of the calculation of the anniversary period, it is necessary to calculate the discharge of existing waterways. That is to know the ability of existing waterways. It is possible to calculate the discharge of rainwater and household wastewater discharge. The calculation results. From the results of the calculations that have been carried out, the results of the channel discharge are Q = 0.665533 m3/second. For the results of the calculation of the maximum channel discharge from household wastewater and rainwater for the next 50 years, namely Q = 0.054320 m3/second. So the dimensions of the existing drainage channels in the field are still capable of flowing rainwater discharge and household waste. The cause of the puddle in front of Citi Mall is because there is a damaged drainage in the Citi Mall parking area and there are weeds and garbage in the drainage in front. Drainage checks are carried out regularly and maintain cleanliness around the canal to avoid negative impacts.
