Abstract
Kawasan Surabaya Barat terutama daerah Menganti, Babatan UNESA dan Babatan Indah merupakan daerah yang sering terjadi banjir. Hal ini terjadi karena pengalihan tata guna lahan terutama untuk pembangunan pemukiman baru. Pembangunan pemukinan tersebut mengakibatkan limpasan air menuju sistem drainase meningkat dan membuat saluran eksisting tidak dapat menampung air yang mengalir. Terutama di kawasan padat sekitar Saluran Sekunder Babatan.
Untuk itu dilaksanakan perencanaan ulang sistem drainase di wilayah Saluran Sekunder Babatan. Perencanaan ulang diawali dengan pengambilan data kondisi eksisting dan data hujan disaluran. Data kondisi eksisting digunakan untuk mengetahui titik-titik genangan dan kapasitas saluran eksisiting. Data hujan digunakan untuk mendapatkan debit inflow yang masuk disaluran. Debit inflow dihitung dengan menggunakan analisa hidrologi sedangkan kapasitas eksisting dihitung menggunakan analisa hidrolika. Disaat kapasitas saluran eksisting melebihi debit yang masuk, maka saluran eksisting tidak bermasalah. Jika kapasitas eksisting kecil dari debit yang masuk, akan ada genangan dan ditanggulangi dengan pembangunan kolam tampung dan perbaikan saluran. Pada analisa awal beberapa saluran eksisting tidak dapat menampung debit yang masuk sehingga dilakukan perbaikan untuk daerah saluran tersier dan penambahan kolam tampung di kawasan sekunder. Perencanaan kolam tampung dilengkapi menggunakan tambahan pompa, dan dalam operasional kolam tampung dilengkapi dengan pintu air.
Dari hasil analisa didapatkan luas kolam tampung yang didesain sebesar 40 m x 400 m x 1.8 m. Kolam tampung juga didesain dilengkapi dengan 2 pompa dengan kecepatan 1 m3/dtk dan 1.5 m3/dtk. Pintu air direncanakan memiliki lebar 2.2 m, tinggi 1.2 m dan tinggi bukaan 0.47 m.
=================================================================
In western Surabaya area usually consists of floods
especially in Meganti, babatan unesa, and babatan indah. This happens because of the diversion of land use for the
construction of new residential. The residential construction
caused the water to the drain
age system improved and made
eksisting channel can’t accommodate the water flow,
especially around the Secondary Channel of babatan area.
To re-planning drainage systems was carried out in
Secondary Channel of babatan area. Re-planning begins with
collecting existing condition data and ra
infall data for each channel. existing condition data is used to determine the point of inundation and capacity of existing channels. Rain data is used to obtain the rate of inflow that goes in the channel.Rate of inflow is calculated by using hydrological analysis while the existing capacity is calculated using hydraulics analysis. While the existing channel capacity exceeds the incoming discharge,
the existing channel is not problematic. If the ex
isting small capacity of the incoming discharge, there will be puddles and overcome by the construction of a pool of containers and repair channels.
In the initial analysis some existing channels can not accommodate incoming discharge so that the improvement for the tertiary channel area and the addition of a container pond in the secondary area. Planning of the pool is equipped with additional pumps, and in the operation of the pond is equipped with a water gate.
From the analysis result, it is found that the designated pond area is 40 m x 400 m x 1.8 m. The storage pool is also designed with 2 pumps with a speed of 1 m3/s and 1.5 m3/s. The planned water gate has a width of 2.2 m, height 1.2 m and aperture height of 0.47 m.
