“…Kota Cimahi memiliki sistem jaringan drainase sebagai pengendalian banjir. Pada umumnya banjir disebabkan oleh curah hujan yang tinggi di atas normal, sehingga sistem pengaliran air yang terdiri dari sungai dan anak sungai alamiah serta sistem saluran drainase dan kanal penampung banjir buatan yang ada tidak mampu menampung akumulasi air hujan tersebut sehingga meluap (Prasetyo, R. D.., et al 2019;Nusantara, D. A. D. 2020;Oktavia, M., et al, 2023). Akan tetapi, dibeberapa titik lokasi di Kota Cimahi sering tejadi banjir akibat limpasan air yang meluap.…”

The drainage system on the Cihanjuang road in Cimahi City experiences flooding problems, especially during the rainy season. Flooding factors are caused by sedimentation, clogged garbage, and rainwater runoff from each settlement that cannot be accommodated. Based on these problems, research was carried out as an effort to overcome the problems that occurred. The method in this research uses a descriptive evaluative method, namely a research method that evaluates conditions objectively/as is. Primary data in this research was obtained by surveying the condition of the drainage channel at the location to determine the dimensions and existing conditions of the channel. Secondary data in this research was obtained via the NASA website in the form of rainfall data for the last 20 years. The rainfall calculation method used in this research is the Log Normal method with a rainfall intensity value of 74.316 mm with a return period of 2 years. This research uses EPA SWMM 5.2.3 computer software as a tool to carry out hydraulic analysis. The research results showed that there were four channel locations with existing drainage channel capacity that could not accommodate water runoff, namely J_10, J_17, J_21, J_48. So that Low Impact Development (LID) planning is carried out in each water catchment area to reduce water runoff. The results obtained show that the application of LID can overcome flooding problems. Apart from that, cost calculations were also carried out in making the four types of LID used, namely Bioretention-cell, Rain Garden, Permeable Pavement and Rain Barrel.

Flooding is a problem that needs to be considered because it affects all sectors. The Bruno River in Kediri Regency often experiences flooding in the rainy season, although the overflow does not reach the settlements. But already, some levees in the Bruno river broke because they could not accommodate the discharge from the Bruno river. Such characteristics have the potential to be the cause of flooding. The core of the problem arranges various flood control efforts. The development of complementary infrastructure such as Water Resources becomes the right choice to overcome the flood event. This research aims to plan Water Resources to control the flood on the Bruno river, Kediri Regency. The analysis includes hydrological analysis and hydraulic analysis. The hydrological analysis includes rainfall calculations, match tests, and flood plans, while hydraulic analysis includes the calculation of bend dimensions. Rainfall data were obtained from kanyoran rain station for the past 10 years. From the rainfall data is done calculations and compared with estimates when re-from related agencies. So, the difference in discharge is known that is used as the basis of the analysis of Water Resources planning. The results of the study obtained flood discharge of 69,20762609 m3/s. ≈ 70 m3/s with a high bend planning bend 4.3m wide 30 m. The elevation of the water level downstream of the bend is +51.56 m so that the planning results can be used as a step to reduce flooding in the Bruno river.

Drainase berfungsi untuk mengalirkan air agar tidak terjadi genangan di permukaan jalan yang dapat mengakibatkan terganggunya aktifitas masyarakat dan rusaknya kontruksi jalan. Di Jalan Harapan Kecamatan Rumbai Pesisir sudah memiliki saluran drainase di bagian kanan dengan tinggi 1,3 m dan lebar 1,3 m, dan saluran kiri dengan tinggi 1,3 m dan lebar 1,1. Namun masih saja sering terjadi genangan air pada permukaan jalan. Kondisi saluran drainase pada jalan harapan mengalami cekungan sehingga menyebabkan tergenangnya air pada daerah tersebut. Tujuan penelitian ini untuk melakukan perencaan ulang guna memperbaiki kondisi saluran drainase yang ada sehingga dapat mengalirkan air. Metode yang digunakan ialah metode Distribusi Gumbel untuk menghitung frekuensi curah hujan, SNI 03-3424-1994 untuk menghitung intensitas curah hujan, dan metode manning untuk menghitung kecepatan aliran. Dari hasil perencanaan didapat dimensi tinggi 1,75 m dan lebar 1,5 m meter dengan elevasi hulu 99,013 dan elevasi hilir 98,8108 untuk saluran kanan dan saluran kiri tinggi 1,45 m dan lebar 1,2 m dengan elevasi hulu 98,429 dan elevasi hilir 98,227 untuk saluran kiri. Kesimpulannya dimensi saluran kanan adalah tinggi 1,75 m dan lebar 1,5 m, pada saluran kiri tinggi 1,45 m dan lebar 1,2m.
