Abstract
Salah satu kawasan kota Surabaya yang sering terjadi
banjir adalah pada DAS Gunungsari yang berada pada wilayah
Surabaya Barat yang terbagi menjadi tiga sub DAS, yaitu sub
DAS Kali Balong, sub DAS Kali Kandangan, dan sub DAS Kali
Sememi. Kondisi topografi wilayahnya merupakan dataran
rendah dan kondisi geografis yang berbatasan dengan laut
menjadikan saluran ini dipengaruhi oleh pasang surut air laut.
Oleh sebab itu perlu direncanakan dimensi saluran yang
mampu menampung debit yang mengalir agar tidak terjadi
limpasan (banjir). Dalam studi ini untuk analisa hidrologi
menggunakan program bantu HEC-HMS.. Sedangkan untuk
analisa hidrolika menggunakan program bantu HEC-RAS.
Berdasarkan hasil analisa didapatkan bahwa lebar saluran
primer Margomulyo bagian hulu sebesar 10 m dan bagian hilir
sebesar 15 m. Untuk lebar bagian hulu Kali Balong sebesar 20 m,
dan 48 m pada bagian hilir. Untuk lebar Kali Kandangan bagian
hulu sebesar 20 m, dan 30 m pada bagian hilir. Sedangkan untuk
Kali Sememi lebar pada bagain hulu sebesar 20 m dan bagian
hilir sebesar 38 m.

One of the areas in Surabaya which frequent flooding in
the watershed Gunungsari is located in West Surabaya which is
devided into three sub-basins which Balong river sub-basins,
Kandangan river sub-basins, and Sememi river sub-basins. The
topography of Surabaya is lowland and geographical conditions
bordering the sea to make this channel is affected by the tide.
Therefore it is necessary to plan the dimensions of the
channel that can accommodate the discharge that flows to
prevent runoff (flood). In this study for the hydrological analysis
using HEC-HMS program. As for the hydraulics analysis using
HEC-RAS program.
Based on the analysis results showed that the
Margomulyo primary channel the width of upstream section of 10
m and downstream sections of 15 m. On Balong River the width
of upstream section of 20 m, and 48 m for downstream section.
For the time width Kandangan upstream part of 20 m, and 30 m
downstream. As for Kali Sememi width at any part of 20 m
upstream and downstream sections of 38 m.
