Abstract
Saluran Kalidami berada di kawasan Surabaya bagian timur. Saluran ini memiliki panjang 7781 meter dengan lebar yang bervariasi antara 15-30 meter. Saluran Kalidami membentang dari Kelurahan Airlangga, Gubeng, Kalisari dan berakhir di Selat Madura. Saat ini 4 km dari hilir saluran Kalidami terdapat boezem yang dilengkapi dengan 4 pintu air dan 2 rumah pompa untuk pengendalian banjir. Namun, saat pompa air dihidupkan ketika hujan, daerah hilir saluran tidak mampu mengalirkan debit buangan pompa sehingga air pada saluran meluap yang diakibatkan oleh pasang air laut, sedimentasi, maupun banyaknya sampah di Kalidami. Dalam Tugas Akhir ini dilakukan perencanaan boezem yang dilengkapi dengan pintu serta pompa air pada hilir saluran Kalidami ini diharapkan air pada saluran tidak meluap sehingga tidak terjadi genangan pada DAS Kalidami. Perencanaan dalam Tugas Akhir ini menggunakan simulasi dengan program bantu Storm Water Management Model (SWMM) 5.1 yang diawali dengan mengumpulkan data hujan harian maksimum di DAS Kalidami, Peta Rencana Tata Ruang Wilayah DAS Kalidami, Peta Jenis Tanah Surabaya, Layout DAS Kalidami, Peta Topografi Surabaya, dan sistem drainase eksisting Kalidami. Data hujan didistribusikan secara statistik untuk memperkirakan probablitas yang akan digunakan, kemudian hasil distribusi tersebut diuji kecocokannya, dan didapatkan curah hujan periode ulang 20 tahun. Dari Peta Rencana Tata Ruang Wilayah dan Peta Jenis Tanah Surabaya didapatkan tata guna lahan DAS Kalidami, Manning’s N Overland Flow, dan Data Infiltrasi. Dari Layout DAS Kalidami dan Peta Topgrafi Surabaya didapatkan subcatchment area dan kontur DAS Kalidami. Dari data sistem drainase Kalidami eksisting didapatkan geometris saluran, Manning’s N for Open Channel, Pengoperasian screw pump dan pompa kalidami. Flow routing dilakukan tiga kali, pertama untuk mengecek sistem drainase Kalidami eksisting terhadap banjir dengan curah hujan periode ulang. Kedua perencanaan ulang berdasarkan evaluasi sistem drainase eksisting bila banjir. Ketiga mengecek boezem dan pengoperasian tiga pompa di sistem drainase Kalidami rencana. Hasil dari Tugas Akhir ini adalah debit limpasan air hujan maksimum pada sistem drainase Kalidami sebesar 88,36 m3/s pada waktu satu jam setelah hujan dimulai. Boezem hilir memiliki luas sebesar 40.000 m2 dengan kedalaman air sebesar 2,5 m. Pompa hilir memiliki 6 unit pompa dengan masing-masing berkapasitas 5 m3/s. Pintu air memiliki lebar 3,5 m, tinggi 2,5 m, tebal 0,03 m, dan diameter stang 3,81 cm dan hasil pengoperasian ketiga pompa adalah; (a) Screw pump mengeluarkan debit 25 m3/s pada elevasi 0,5 – 2 m. (b) Pompa Kalidami mengeluarkan debit 10 m3/s pada elevasi 0,5m, 20 m3/s pada elevasi 0,6 – 0,7 m, 25 m3/s pada elevasi 0,8 – 0,9 m, 30 m3/s pada elevasi 1 – 1,1 m, 35 m3/s pada elevasi 1,2 – 1,3 m, 40 m3/s pada elevasi 1,4 – 1,5 m, 45 m3/s pada elevasi 1,6 – 2 m. (c) Pompa hilir mengeluarkan debit 10 m3/s pada elevasi 0,5 – 0,7 m, 15 m3/s pada elevasi 0,8 – 1,1 m, 20 m3/s pada elevasi 1,2 – 1,4 m, 25 m3/s pada elevasi 1,5 – 1,7 m, 30 m3/s pada elevasi 1,8 – 2,5 m.
=================================================================================================================================
The Kalidami channel is located at eastern Surabaya. This channel is 7781 meters in length with various width of 15 to 30 meters. The Kalidami channel stretches from Airlangga village, Gubeng, Kalisari, and ends at the Madura Strait. Currently, 4 km downstream of the Kalidami channel, a boezem equipped with 4 tide gates and 2 pump houses for flood control could be located. However, if the water pump is actived during rain, the channel’s downstream is unable to drain the discharge of the pump which causes overflowing due to tides, sedimentation, or the excessive amount of garbage in Kalidami. It is expected that the water overflow which leads to inundation will stop around the Kalidami Watershed.
The Planning of this Final Project is using simulation with the support of Storm Water Management Model (SWMM) 5.1 begins with collecting maximum daily rainfall data in the Kalidami Watershed, Map of Kalidami Watershed Spatial Planning, Map of Surabaya Soil Types, Kalidami Watershed Layout, Surabaya Topographical Map, and the existing Kalidami drainage system. Rainfall data is distributed statistically to estimate probability, then the results of the distribution are tested for compabiluty. This test result a 20-year rainfall return period. From the Map of Spatial Planning and Map of Surabaya Soil Types, the land uses of the Kalidami Watershed, Manning’s N Overland Flow, and Infiltration Data are obtained. The Kalidami watershed contour and subcatchment area are obtained for the Kalidami Watershed Layout and Surabaya Topographical Map;other datas such as geometric channels, Manning’s N for Open Channel, and screw pump and kalidami pump operation are obtained from the existing Kalidami drainage system against floods with return period rainfall, second to do re-planning based in existing drainage system during flood evaluation, and third to check boezem and the operation of three pumps at the planned drainage system. The result of this final project is the maximum rainwater runoff in the Kalidami drainage system at the number of 88.36 m3/s within one hour after the rain starts. The planned boezem has the area of 40.000 m2 with the depth of water 2.5 m. There will be 6 units of pumps each with the capacity of 5 m3/s. Tide gates have a width of 3,5 m, height of 2,5 m, thickness of 0,03 m, and handlebar diameter 3,81 cm. the operation of three pumps result in (a) the screw pump releases a flow rate of 25 m3/s at the elevation between 0.5 – 2 m. (b) the Kalidami pump releases a flow rate of 10 m3/s at the elevation of 0.5 m, 20 m3/s at the elevation between 0.6 – 0.7 m, 25 m3/s at the elevation between 0.8 – 0.9 m, 30 m3/s at the elevation between 1 – 1.1 m, 35 m3/s at the elevation between 1.2 – 1.3 m, 40 m3/s at the elevation between 1.4 – 1.5 m, and 45 m3/s at the elevation between 1.6 - 2 m. (c) the downstream pump releases a flow rate between 10 m3/s at the elevation of 0.5 – 0.7 m, 15 m3/s at the elevation between 0.8 – 1.1 m, 20 m3/s at the elevation between 1.2 – 1.4 m, 25 m3/s at the elevation of 1.5 – 1.7 m, 30 m3/s at the elevation between 1.8 - 2 m.
