Analisis Kapasitas Saluran Drainase Menggunakan Program SWMM 5.1 di Perumahan Tasmania Bogor, Jawa Barat

Abstract

The intensity and duration of rainfall will affect the amount of runoff. A proper drainage design is needed so that runoff from maximum rainfall would not cause a problem such as excess water or flood. The purpose of this research were to analyze the runoff volume in Tasmania Regency, Bogor and get drainage network design in accordance with the runoff that occured. Analysis was carried out using SWMM 5.1 software with designed rainfall was calculated using the Log-Person III method of 147.2 mm. Peak discharge runoff from simulation results were 0.01 -0.08 m3/s. Based on the simulation there were 20 channels overflowed during maximum runoff and 6 channels were high potentially overflowed so that repairs were also needed. The factors that influenced were the amount of runoff, channels capacity were lower than runoff volume, and the low infiltration value of subcatchment so that only a little water could be infiltrated and the rest of rainfall became runoff..

Storm water management model to evaluate urban inundation in Lowokwaru and Blimbing sub-catchments in the city of Malang

“…Hourly rainfall intensity data is crucial as input parameters for the rain gauge in SWMM [3][4][5][6][7][8][9]. The determining of this parameter utilized the Mononobe method, which is a method that is still often used for the analysis of urban flooding in Indonesia.…”

“…In these two regions, the problem of inundation exists at numerous points that have not received effective management. This effort requires analysis of inundation based on existing conditions, followed by analysis using an SWMM (storm water management model) to find out the reduction capabilities of existing drainage channels and to visualize inundation on the field, comparison with data of inundation locations as validation, and analysis of solutions for the management of inundation [2][3][4][5][6]. This research is significant because urban flooding analysis is often not completed well due to the resolution of inundation problems not having utilized the concept of a catchment area as a sub-system.…”

Analisis Kapasitas Saluran Drainase Kelurahan Kalipang Kecamatan Sutojayan Kabupaten Blitar menggunakan EPA SWMM 5.1

“…Permukaan tanah yang sebelumnya digunakan sebagai daerah tangkapan air berubah penggunaannya menjadi bangunan dan jalan, yang menyebabkan peningkatan kelebihan air di permukaan, terutama pada musim hujan. Dengan semakin sedikitnya tangkapan, maka jumlah limpasan yang tidak terserap oleh tanah semakin besar dan dapat mengakibatkan genangan genangan yang dapat menyebabkan banjir pada musim hujan [3].…”

“…SWMM adalah perangkat lunak yang dikembangkan khusus untuk mensimulasikan aliran hujan dinamis. Program ini bisa meniru dampak limpasan air hujan suatu daerah pada sistem drainase dalam jangka pendek dan jangka panjang serta memiliki banyak pilihan alternatif untuk menanggulangi masalah banjir [8]. Kelebihan dari software SWMM 5.1 dapat melihat hasil simulasi melalui kode warna, grafik dan tabel, profil, serta analisis frekuensi statistik dalam bentuk format area drainase [9].…”
