Abstract

Drainage is a basic facility that must be provided to meet community needs, so it’s very important in urban spatial planning. The benefit of building drainage is to prevent stagnant water so that it does not interfere with community activities. The condition of the drainage channels on Jalan Marina isn’t maintained because the dimensions of the channels are small and sedimentation occurs, causing silting of the channels. This causes floods that always occur every year. Re-dimension of the drainage channel was carried out because the initial dimensions could not accommodate the planned flood discharge. Some of data the basic for determining the re-dimensional drainage channels are rainfall data, sea tide data, and initial drainage channel dimension data. From the calculation results, the value of planned flood discharge is 172.634 mᶟ/s. So, the dimensions of the drainage channel are re-planned because the channel discharge value is smaller than the planned flood discharge value. The results of this study are that the planned flood discharge is greater than the drainage channel water discharge so that the initial channel dimensions cannot accommodate water. The results of re-planning the dimensions of the drainage channel based on the planned flood discharge value are h of 8.5 meters, b of 9.8 meters, and W of 2 meters. Re-dimensional planning of the drainage channel is fulfilled because Qs

滨海湾地区的排水管道正常化，以防止洪水

排水是满足社区需求的基础设施，在城市空间规划中占有重要地位。建筑排水系统的好处是防止积水，使其不会干扰社区活动。嘉兰码头的排水渠道状况没有得到维持，因为渠道尺寸小，泥沙淤积，导致渠道淤积。这就导致了每年都会发生的洪水。由于最初的尺寸不能适应计划的洪水流量，因此重新确定了排水通道的尺寸。降水资料、海潮资料和初始排水渠维数是确定排水渠重维数的基础资料。由计算结果可知，规划洪流量为172.634 mᶟ/s。因此，由于河道流量值小于规划的洪水流量值，重新规划了排水通道的尺寸。研究结果表明:规划洪水流量大于排水渠道水量，导致河道初始尺寸无法容纳水量。根据规划泄洪量对排水渠尺寸进行重新规划的结果为:h为8.5 m, b为9.8 m, W为2 m。由于Qs
