Abstract

Sudetan Sungai Ciiwung ke Kanal Banjir Timur (KBT) merupakan salah satu cara untuk mengurangi banjir pada Sungai Ciliwung. Bangunan ini diharapkan mampu mengalihkan debit banjir sungai Sungai Ciliwung ke KBT sebesar 60 m3/detik. Penelitian ini bertujuan untuk mengevaluasi hasil model fisik dengan melakukan perbandingan aliran pada model fisik terhadap perhitungan secara teoritis dan analisa satu dimensi menggunakan HEC-RAS. Perhitungan teoritis dilakukan dengan metode De Marchi, side weir, percabangan anak sungai dan aliran melalui pulau. Perhitungan melalui 4 metode dan hasil simulasi HEC-RAS didapatkan beberapa perbedaan terhadap debit, kecepatan dan tinggi muka air pada inlet floodway (sudetan) Sungai Ciliwung ke KBT namun tidak terlalu signifikan. Baik hasil uji model fisik maupun perhitungan teoritis dan simulasi HEC-RAS debit 60 m3/detik dapat terjadi apabila elevasi muka air di Sungai Ciliwung diatas +12,342 m.
