STUDI DRAINASE BRATANG DAN SEKITARNYA DI KOTA SURABAYA

THE DRAINAGE STUDY OF BRATANG AND AROUND IN SURABAYA CITY

Author :
Tuti, Ika Rahayu Purwaning Tias 




ABSTRAK

Daerah Bratang yang terletak di bagian timur Kota Surabaya merupakan daerah pemukiman padat dengan perkembangan yang cukup pesat sejak tahun 1989. Walaupun daerah ini sudah dilengkapi dengan suatu sistem drainase yang menggunakan cara pengaliran gravitasi dan pompa ternyata masih selalu mengalami banjir. Hal ini menimbulkan pertanyaan dimana letak kesalahannya sehingga sistem drainase yang ada belum menunjukkan kinerja yang optimal untuk menjawab pertanyaan tersebut diperlukan studi yang mencakup kinerja tiap-tiap komponen saluran mulai saluran tersier saluran sekunder sampai dengan saluran primer yang bermuara di Kali Sumo dan kinerja boezem dan pompa yang ada mengacu pada debit banjir rencana 2 tahunan untuk saluran tersier debit rencana 5 tahunan untuk saluran sekunder dan debit rencana 10 tahunan untuk saluran primer. Disamping itu di dalam studi ini juga ditinjau pemeliharaan saluran boezem dan pompa. Dari hasil studi ternyata sistem pengaliran gravitasi saja ternyata tidak cukup sehingga diperlukan bantuan sistem pompa pada saat elevasi Kali Wonokromo lebih tinggi dari elevasi muara Kali Sumo. Dengan kombinasi aliran gravitasi dan pompa tersebut ternyata masih diperlukan normalisasa saluran.


ABSTRACT

Bratang area which located in east Surabaya city is a dense settlement with rapid development enough since 1989. Althought this area has been equipped with a drainage system which using current gravity and pump there is still having problem with floods. It makes a question where the main problem occurs hence the drainage system did not show optimal achievement Study is needed to answer those question which including the achievement of each pipeline parts beginning at tersier pipeline secunder pipeline to primer pipeline which flowing to Sumo river the work of boezem achievement and pump referred flood discharge design of two annual to tersier pipeline flood discharge design of five annual to secunder pipeline and flood discharge design of ten annual to primer pipeline. In addition this research also study about pipeline maintenance boezem and pump. As a result of study gravity current system is not enought yet hence it needs pump system when Wonokromo river elevations higher than Sumo river elevations. By combining current gravity and pump there is still needing channel normalization
